You’re describing how ancient magnetic core memory works, that’s not how modern DRAM (Dynamic RAM) works. DRAM uses a constant pulsing refresh cycle to recharge the micro capacitors of each cell.
And on top of that, SRAM (Static RAM) doesn’t even need the refresh circuitry, it just works and holds it’s data as long as it remains powered. It only takes 2 discreet transistors, 2 resistors, 2 buttons and 2 LEDs to demonstrate this on a simple breadboard.
I’m taking a wild guess that you’ve never built any circuits yourself.
Do you really trust the results of any computing system, no matter how it’s designed, when it has pathetic memory integrity compared to ancient technology?
And you would have been there shitting on magnetic core memory when it came out. But without that we wouldn’t have the more advanced successors we have now.
Core memory loses information on read and DRAM is only good while power is applied. Your street dime will be readable practically forever and your abacus is stable until someone kicks it over.
You’re not the arbiter of what technology is “good enough” to warrant spending money on.
Core memory is also designed to accomodate for that and almost instantly rewrite the data back to memory. That in itself might be a crude form of ‘error’ correction, but it still lasts way longer than an hour.
Granted that quantum computers are a different beast of their own, how much digital data does a qbit actually store? And how does that stack up in price per bit comparison?
If they already know quantum computers are more prone to memory errors, why not just use reliable conventional RAM to store the intermediate data and just let the quantum side of things just be the ‘CPU’, or QPU if you like?
I dunno, it just makes absolutely no sense to me to utilitze any sort of memory technology that even with error correction still manages to lose information faster than a jumping spider’s memory?
Must be the dumbest take on QC I’ve seen yet. You expect a lot of people to focus on how it’ll break crypto. There’s a great deal of nuance around that and people should probably shut up about it. But “dime stuck in the road is a stable datapoint” sounds like a late 19th century op-ed about how airplanes are impossible.
Welp, quantum computers have certain advantages (finding elements in O(sqrt(n)) time complexity, factorizing primes, etc). The difficulty is actually making everything stable because these machines are pretty complex.
As stable as that dime is, it’s utterly useless for all practical purposes.
What Google is talking about it making a stable qbit - the basic unit of a quantum computer. It’s extremely difficult to make a qbit stable - and as it underpins how a quantum computer would work instability introduces noise and errors into the calculations a quantum computer would make.
Stabilising a qbit in the way Google’s researchers have done shows that in principle if you scale up a quantum computer it will get more stable and accurate. It’s been a major aim in the development of quantum computing for some time.
Current quantum computers are small and error prone. The researchers have added another stepping stone on the way to useful quantum computers in the real world.
Do you have any idea the amount of error correction needed to get a regular desktop computer to do its thing? Between the peripheral bus and the CPU, inside your RAM if you have ECC, between the USB host controller and your printer, between your network card and your network switch/router, and so on and so forth. It’s amazing that something as complex and using such fast signalling as a modern PC does can function at all. At the frequencies that are being used to transfer data around the system, the copper traces behave more like radio frequency waveguides than they do wires. They are just “suggestions” for the signals to follow. So there’s tons of crosstalk/bleed over and external interference that must be taken into account.
Basically, if you want to send high speed signals more than a couple centimeters and have them arrive in a way that makes sense to the receiving entity, you’re going to need error correction. Having “error correction” doesn’t mean something is bad. We use it all the time. CRC, checksums, parity bits, and many other techniques exist to detect and correct for errors in data.
I’m well aware. I’m also aware that the various levels of error correction in a typical computer manage to retain the data integrity potentially for years or even decades.
Google bragging about an hour, regardless of it being a different type of computer, just sounds pathetic, especially given all the money being invested in the technology.
Traditional bits only have to be 0 or 1. Not a coherent superposition.
Managing to maintain a stable qubit for a meaningful amount of time is an important step. The final output from quantum computation is likely going to end up being traditional bits, stored traditionally, but superpositions allow qubits to be much more powerful during computation.
Being able to maintain a cached superposition seems like it would be an important step.
It can be useful if they build enough of these that they can run programs that regular computers can’t run at this scale, in less than an hour.
Quantum computers aren’t a replacement for regular computers because they’re much slower and can’t do normal calculations, but they can do the type of problem where you have to guess-and-check too many answers to be feasible with regular computers in many fewer steps.
I took a random wild guess, and found that if they quit blowing billions of dollars on over-complicated technology, they could do a lot more to take care of real world problems, like food, clothes and shelter for the homeless.
By simulating molecules, quantum computers have a huge promise of creating new medicines that are more effective, have fewer side effects, and are more likely to get through FDA trials on the first try.
So what you’re saying is we should never make any scientific advancement until we make the world a paradise?
You know what would be at more effective, and just as realistic? Setting a limit that no one person or entity should have more than a half a billion dollars. The rest goes to charity to take care of all the problems we have now.
I totally get you there, yes no one person should have over half a billion dollars while so many others plus the environment are suffering.
As far as scientific advancement, I think humanity is already reaching the peak of that mountain. Sure there’s still more to be discovered, but at what cost?
How much does it cost in research and design, manufacturing and programming a quantum computer? I dunno what their finances look like, but if I had to spot a wild guess, that already sounds like over half a billion dollars…
Interesting you get downvoted for this when I mocked someone for saying the opposite who claimed that $0.5m was some enormous amount of money we shouldn’t be wasting, and I simply pointed out that we waste literally billions around the world on endless wars killing random people for now reason, so it is silly to come after small bean quantum computing if budgeting is your actual concern. People seemed to really hate me for saying that, or maybe it was because they just actually like wasting moneys on bombs to drop on children and so they want to cut everything but that.
Because quantum physics. A qubit isn’t 0 or 1, it’s both and everything in between. You get a result as a distribution, not as distinct values.
Qubits are represented as (for example) quantumly entangled electron spins. And due to the nature of quantum physics, they are not very stable, and you cannot measure a value without influencing it.
Granted, my knowledge of quantum computing is very hand-wavy.
I do get that, yes it’s more complicated than I can fully wrap my brain around as well. But it also starts to beg the question, how many billions of dollars does it take to reinvent the abacus?
Again, I realize there’s a bit of a stark difference between the technologies, but when does the pursuit of over-complicated technology stop being worth it?
Shit, look at how much energy these AI datacenters consume, enough to power a city or more. Look at how much money is getting pumped into these projects…
Ask the AI how to deal with the energy crisis, I’ll only believe it’s actually intelligent when it answers “Shut me and all the other AI datacenters off, and recycle our parts for actual useful purposes.”
Blowing billions on quantum computing ain’t helping feed, clothe and house the homeless…
Contrarian much, you have multiple answers for exactly the answer you asked for.
As a species, the one thing that defines us is the pursuit of technology to overcome our natural physical ability. We are currently hitting a wall in regard to electron based computing.
I think you’re confusing technology with politics to the point you’re just making a point unrelated to the topic.
All tech raises the standard if that’s then used by people to horde resources and have an unbalance in quality of life that’s a policy issue not one of the technology.
What a sad view of humanity to think that our one defining characteristic should be pursuit of technology rather than the ability to intelligently collaborate and thereby form communities with a shared purpose.
I can assure you that the success of human survival throughout the history of our species has had far more to do with community and resourcefulness than with technological advancement. In fact it should be clear by now technological advancement devoid of communal spirit will be the very thing that brings an untimely end to our entire species. Our technology is destroying the climate we depend on and depleting the soil that we need for growing food, to say nothing of the nuclear bombs that could wipe us out with the wrong individuals in positions of power.
You’ve kind of whiffed what I said, at no point did I talk about tech over all else like some kind of Adeptus Mechanicus :D
My take here is that our grasp of tech is what allowed us to surpass other animals. Again, looking at “technology” in some really shallow one dimensional way. There are tons of environmental and communal benefits we’ve gained through our technological pursuits, the sad view is maybe thinking all tech things are bad and viewing that part of our world only in its moral inferiorities. Our domestication of fire being a prime example of a technology benefitting our social and communal enrichment.
Good job moving the conversation further away from the post
I’m directing my criticism specifically on the technological advancement which is devoid of communal spirit, not on all technological advancement categorically.
Crediting human achievement to technological advancement is a mistake in my opinion. Technological advancement is not inherently good or bad. Communal spirit is what determines whether technology yields positive or negative outcomes. That’s the real ingredient behind everything humans have achieved throughout history.
Sadly techno-optimism has become a prevailing mindset in today’s world where people and institutions don’t want to take responsibility for the consequences of their actions because of belief that as-yet-unknown technological advancement will bail us out in the future, even when there’s no evidence that it will even be physically possible.
But what I said is that your view is a sad one, not an incorrect one. The truth is, technological advancement may truly end up being the defining characteristic of humanity. After all, when we think about extinct species, we tend to associate them most strongly with what made them extinct. Just as we associate the dinosaurs most strongly with a meteor, maybe an outside observer will some day associate humanity most strongly with the technology that sent us out in a blaze of glory.
The Voyager 1 is still (mostly) ticking after almost 50 years with basically ancient technology by today’s standards, and it’s been through the hell of deep space, radiation and shit all that time.
What’s wrong with old technology if it still works? I don’t care what all magical computations a quantum computer can do, a mere hour of data retention just sounds pathetic in comparison.
You know we’re going to lose contact with V1 this decade, and as of last year the data stopped making sense? Which tied into my criticism of your other comment, we’re getting close (in the grand scheme) to how small we can make a transistor so we just make clusters of electron based compute models each running its own resources or do we invest in finding a better more efficient way?
Yes, I’m aware. ~50 years is a little over ~438,000 hours of service time, with no ability to even perform physical hands on maintenance.
How is a pathetic one hour memory of any sort somehow progress? By the time it cures cancer or whatever, the data is still that much more likely to be corrupt by the time they check it and try to save it.
I tend to agree with this. It’s why I’ve become less and less interested in the advancement of technology and more interested in ways to use the tech we have to build community.
No, they both very much share something in common. Money and resources, that could otherwise be invested in trying to actually fix the world’s problems.
What are they gonna do with a quantum computer, cure cancer? Then by the time the scientists get to check out the results, the results done got corrupted because of pathetic memory integrity, and it somehow managed to create a new type of cancer with the corrupted results…
Ya know, as much hype as there has been for the idea of quantum computing, I haven’t even so much as seen a snippet of source code for it to even say Hello World.
Even if that’s not exactly what these machines are meant for, seriously, where’s even a snippet of code for people to even get a clue how (and if) they even work as they’re hyped to be?
Nobody sees what they don’t look for. This is seven seconds of using duckduckgo with the following query : “what does code for a quantum computer look like?”
I don’t pretend to understand this, as I’m not a computer scientist, even less so a quantum scientist. Quite honestly, if you allow me a bit of criticism, I think you’re interacting with this whole topic in bad faith. Moving goalposts, obviously not doing any kind of documentation effort before criticizing an entire field of research, claiming that development efforts should go towards some vaguely defined “fixing the world problems”…
Pulling a serious comment from your third link only reinforces practically everything I’ve been getting at…
“The problem of showing a ‘hello world’ of quantum computing is that we’re basically still as far from quantum computers as Leibnitz or Babbage were from your current computer. While we know how they should operate theoretically, there is no standard way of actually building a physical quantum computer. A side-effect of that is that there is no single programming model of quantum computing. Textbooks such as Nielsen et al. will show you a ‘quantum circuit’ diagram, but those are far from formal programming languages: they get a little ‘hand-waving’ on the details such as classical control or dealing with input/output/measurement results.”
The computers we have today help to do logistics to “feed, clothe and house the homeless”. They also help you to advocate to do more. How much of that would be comprehensible to someone living in 1900?
I’m not sure that homelessness is a problem quantum computing or AI are suitable for. However, AI has already contributed in helping to solve protein folding problems that are critical in modern medicine.
Solving homelessness and many other problems isn’t resource constrained as you think. It’s more about the will to solve them, and who profits from leaving them unsolved. We have known for decades that providing homes for the homeless in a large city actually saves the city money, but we’re still not doing it. Renewable energy has been cheaper than fossil fuels for almost as long. Medicare for all would cost significantly less than the US private healthcare system, and would lead to better results, but we aren’t doing that either.
The output of a quantum computer is read by a classical computer and can then be transferred or stored as long as you liked use traditional means.
The lifetime of the error corrected qubit mentioned here is a limitation of how complex of a quantum calculation the quantum computer can fix. And an hour is a really, really long time by that standard.
Breaking RSA or other exciting things still requires a bunch of these error corrected qubits connected together. But this is still a pretty significant step.
Well riddle me this, if a computer of any sort has to constantly keep correcting itself, whether in processing or memory, well doesn’t that seem unreliable to you?
Hell, with quantum computers, if the temperature ain’t right and you fart in the wrong direction, the computations get corrupted. Even when you introduce error correction, if it only lasts an hour, that still doesn’t sound very reliable to me.
On the other hand, I have ECC ChipKill RAM in my computer, I can literally destroy a memory chip while the computer is still running, and the system is literally designed to keep running with no memory corruption as if nothing happened.
That sort of RAM ain’t exactly cheap either, but it’s way cheaper than a super expensive quantum computer with still unreliable memory.
Well riddle me this, if a computer of any sort has to constantly keep correcting itself, whether in processing or memory, well doesn’t that seem unreliable to you?
Error correction is the study of the mathematical techniques that let you make something reliable out of something unreliable. Much of classical computing heavily relies on error correction. You even pointed out error correction applied in your classical computer.
That sort of RAM ain’t exactly cheap either, but it’s way cheaper than a super expensive quantum computer with still unreliable memory.
The reason so much money is being invested in the development of quantum computers is mathematical work that suggests a sufficiently big enough quantum computer will be able to solve useful problems in an hour that would take the worlds biggest classical computer thousands of years to solve.
Why do we humans even think we need to solve these extravagantly over-complicated formulas in the first place? Shit, we’re in a world today where kids are forgetting how to spell and do basic math on their own, no thanks to modern technology.
Don’t get me wrong, human curiosity is an amazing thing. But that’s a two edged sword, especially when we’re augmenting genuine human intelligence with the processing power of modern technology and algorithms.
Just because we can, doesn’t necessarily mean we should. We’re gonna end up with a new generation of kids growing up half dumb as a stump, expecting the computers to give us all the right answers.
Why do we humans even think we need to solve these extravagantly over-complicated formulas in the first place?
Because those questions could do things like cure disease or help us better understand the universe or a million other things
Shit, we’re in a world today where kids are forgetting how to spell and do basic math on their own, no thanks to modern technology.
Not because of it, either. This research isn’t really related to that kind of tech, either
Just because we can, doesn’t necessarily mean we should. We’re gonna end up with a new generation of kids growing up half dumb as a stump, expecting the computers to give us all the right answers.
This isn’t going to be for daily normal use, you’re projecting fear at the wrong tech
Ask a quantum chip how to cure a disease? Sure, let’s accept that as a possible future…
You really think the chips actually understand diseases? We’re gonna end up with a whole new generation of people that have no clue how the shit works to begin with.
Eventually it’ll be like “How do I trim my toenails?”, while the ‘intelligent’ system responds to cut your appendages off.
Granted that AI and quantum computing aren’t quite the same thing. Does it matter? Future generations will have the ability to just ask a computer how to generate cure a disease…
The machine gives no fucks about us, it’ll just as easily destroy us if someone asks the wrong question or enters the wrong formula.
Why do we humans even think we need to solve these extravagantly over-complicated formulas in the first place? Shit, we’re in a world today where kids are forgetting how to spell and do basic math on their own, no thanks to modern technology.
lol.
All of modern technology boils down to math. Curing diseases, building our buildings, roads, cars, even how we do farming these days is all heavily driven by science and math.
Sure, some of modern technology has made people lazy or had other negative impacts, but it’s not a serious argument to say continuing math and science research in general is worthless.
Specifically relating to quantum computing, the first real problems to be solved by quantum computers are likely to be chemistry simulations which can have impact in discovering new medicines or new industrial processes.
There’s a dime stuck in the road behind our local store, tails side up, for over 15 years. And that doesn’t even need error correction.
Why does it sound like technology is going backwards more and more each day?
Someone please explain to me how anything implementing error correction is even useful if it only lasts about an hour?
I mean, that’s literally how research works. You make small discoveries and use them to move forward.
What’s to research? A fucking abacus can hold data longer than a goddamn hour.
Are you really comparing a fucking abacus to quantum mechanics and computing?
they are baiting honest people with absurd statements
Russian election interference money dried up and now they’re bored
They are shaking some informative answers out of literate people so I’m getting something out of it :D
True
Absurdly ignorant questions that, when answered, will likely result in people knowing more about quantum computing than they did before.
And if it stopped there, we’d all be the better for it :)
Don’t feed the trolls.
Yes, as far as memory integrity goes anyways. Hell, even without an abacus, the wet noodle in my head still has better memory integrity.
Are you aware that RAM in your Computing devices looses information if you read the bit?
Why don’t you switch from smartphone to abacus and dwell in the anti science reality of medieval times?
And that it looses data after merely a few milliseconds if left alone, that to account for that, DDR5 reads and rewrites unused data every 32ms.
You’re describing how ancient magnetic core memory works, that’s not how modern DRAM (Dynamic RAM) works. DRAM uses a constant pulsing refresh cycle to recharge the micro capacitors of each cell.
And on top of that, SRAM (Static RAM) doesn’t even need the refresh circuitry, it just works and holds it’s data as long as it remains powered. It only takes 2 discreet transistors, 2 resistors, 2 buttons and 2 LEDs to demonstrate this on a simple breadboard.
I’m taking a wild guess that you’ve never built any circuits yourself.
I’m taking a wild guess that you completely ignored the subject of the thread to start an electronics engineering pissing contest?
Do you really trust the results of any computing system, no matter how it’s designed, when it has pathetic memory integrity compared to ancient technology?
That is not a product. This is research.
And you would have been there shitting on magnetic core memory when it came out. But without that we wouldn’t have the more advanced successors we have now.
Nah, core memory is alright in my book, considering the era of technology anyways. I would have been shitting on the William’s Tube CRT Memory system…
https://youtube.com/watch?v=SpqayTc_Gcw
Though in all fairness, at the time even that was something of progress.
Doubt.
Core memory loses information on read and DRAM is only good while power is applied. Your street dime will be readable practically forever and your abacus is stable until someone kicks it over.
You’re not the arbiter of what technology is “good enough” to warrant spending money on.

But “dime stuck in the road is a stable datapoint” sounds like a late 19th century op-ed about how airplanes are impossible.
The internet is pointless, because you can transmit information by shouting. /s
AND I can shout while the power is out. So there!
Not to mention that quantum cryptography has found ways to prevent that already.
Welp, quantum computers have certain advantages (finding elements in O(sqrt(n)) time complexity, factorizing primes, etc). The difficulty is actually making everything stable because these machines are pretty complex.
https://en.wikipedia.org/wiki/Quantum_supremacy

You disrespect the meaning of based
He meant base

It sounds like your saying a large quantum computer is easier to make than a small quantum computer?
That is one of the things the article says. That making certain parts of the processor bigger reduces error rates.
I think that means the current quantum computers made using photonics, right? Those are really big though.
Do you have any idea the amount of error correction needed to get a regular desktop computer to do its thing?

You think that’s wasteful? Wait until you hear about the military or prisons.
Or the consumerist world in general
Don’t forget crypto currencies.
Boomer-ass take
Uhhh…boomers made NASA
But… you know even if they didn’t use the money for this, they wouldn’t use it for those things, right? It’s Google…
Just think of how many messaging apps they could launch and then kill with that money.
I’d forgotten all about Google+ until you made this observation

Yes, I’m aware. ~50 years is a little over ~438,000 hours of service time, with no ability to even perform physical hands on maintenance.
How is a pathetic one hour memory of any sort somehow progress? By the time it cures cancer or whatever, the data is still that much more likely to be corrupt by the time they check it and try to save it.
1 hour < 438,290 hours
I tend to agree with this. It’s why I’ve become less and less interested in the advancement of technology and more interested in ways to use the tech we have to build community.
Thank you, at least someone gets the gist of what I mean 👍
Your problem is capitalism, not QC.
But this is not just any abacus, it’s one that calculates all the results at once. That is a disruptive leap forward in computing power.
“AI” as it stands now is unrelated to quantum computing
No, they both very much share something in common. Money and resources, that could otherwise be invested in trying to actually fix the world’s problems.
What are they gonna do with a quantum computer, cure cancer? Then by the time the scientists get to check out the results, the results done got corrupted because of pathetic memory integrity, and it somehow managed to create a new type of cancer with the corrupted results…
Well yes, quite possibly, through protein behavior modeling. Do some reading !

Ya know, as much hype as there has been for the idea of quantum computing, I haven’t even so much as seen a snippet of source code for it to even say Hello World.
Even if that’s not exactly what these machines are meant for, seriously, where’s even a snippet of code for people to even get a clue how (and if) they even work as they’re hyped to be?
Nobody sees what they don’t look for. This is seven seconds of using duckduckgo with the following query : “what does code for a quantum computer look like?”

I don’t pretend to understand this, as I’m not a computer scientist, even less so a quantum scientist. Quite honestly, if you allow me a bit of criticism, I think you’re interacting with this whole topic in bad faith. Moving goalposts, obviously not doing any kind of documentation effort before criticizing an entire field of research, claiming that development efforts should go towards some vaguely defined “fixing the world problems”…
Your first link is paywalled, fuck that.
Pulling a serious comment from your third link only reinforces practically everything I’ve been getting at…
“The problem of showing a ‘hello world’ of quantum computing is that we’re basically still as far from quantum computers as Leibnitz or Babbage were from your current computer. While we know how they should operate theoretically, there is no standard way of actually building a physical quantum computer. A side-effect of that is that there is no single programming model of quantum computing. Textbooks such as Nielsen et al. will show you a ‘quantum circuit’ diagram, but those are far from formal programming languages: they get a little ‘hand-waving’ on the details such as classical control or dealing with input/output/measurement results.”
The computers we have today help to do logistics to “feed, clothe and house the homeless”. They also help you to advocate to do more. How much of that would be comprehensible to someone living in 1900?
I’m not sure that homelessness is a problem quantum computing or AI are suitable for. However, AI has already contributed in helping to solve protein folding problems that are critical in modern medicine.
Solving homelessness and many other problems isn’t resource constrained as you think. It’s more about the will to solve them, and who profits from leaving them unsolved. We have known for decades that providing homes for the homeless in a large city actually saves the city money, but we’re still not doing it. Renewable energy has been cheaper than fossil fuels for almost as long. Medicare for all would cost significantly less than the US private healthcare system, and would lead to better results, but we aren’t doing that either.
“Only”? The “industry standard” is less than a millisecond.
Show the academic world how many computational tasks the physical structure of that coin has solved in the 15 years.
You’re forgetting the difference between processing and memory. The posted article is about memory.
If the memory sucks compared to standards of half a century ago, then they just suck.
How many calculations can your computer do in an hour? The answer is a lot.
Indeed, you’re very correct. It can also remember those results for over an hour. Hell, a jumping spider has better memory than that.
The output of a quantum computer is read by a classical computer and can then be transferred or stored as long as you liked use traditional means.
The lifetime of the error corrected qubit mentioned here is a limitation of how complex of a quantum calculation the quantum computer can fix. And an hour is a really, really long time by that standard.
Breaking RSA or other exciting things still requires a bunch of these error corrected qubits connected together. But this is still a pretty significant step.
Well riddle me this, if a computer of any sort has to constantly keep correcting itself, whether in processing or memory, well doesn’t that seem unreliable to you?
Hell, with quantum computers, if the temperature ain’t right and you fart in the wrong direction, the computations get corrupted. Even when you introduce error correction, if it only lasts an hour, that still doesn’t sound very reliable to me.
On the other hand, I have ECC ChipKill RAM in my computer, I can literally destroy a memory chip while the computer is still running, and the system is literally designed to keep running with no memory corruption as if nothing happened.
That sort of RAM ain’t exactly cheap either, but it’s way cheaper than a super expensive quantum computer with still unreliable memory.
Error correction is the study of the mathematical techniques that let you make something reliable out of something unreliable. Much of classical computing heavily relies on error correction. You even pointed out error correction applied in your classical computer.
The reason so much money is being invested in the development of quantum computers is mathematical work that suggests a sufficiently big enough quantum computer will be able to solve useful problems in an hour that would take the worlds biggest classical computer thousands of years to solve.
Why do we humans even think we need to solve these extravagantly over-complicated formulas in the first place? Shit, we’re in a world today where kids are forgetting how to spell and do basic math on their own, no thanks to modern technology.
Don’t get me wrong, human curiosity is an amazing thing. But that’s a two edged sword, especially when we’re augmenting genuine human intelligence with the processing power of modern technology and algorithms.
Just because we can, doesn’t necessarily mean we should. We’re gonna end up with a new generation of kids growing up half dumb as a stump, expecting the computers to give us all the right answers.
Smart technology for dumb people…
Because those questions could do things like cure disease or help us better understand the universe or a million other things
Not because of it, either. This research isn’t really related to that kind of tech, either
This isn’t going to be for daily normal use, you’re projecting fear at the wrong tech
Ask a quantum chip how to cure a disease? Sure, let’s accept that as a possible future…
You really think the chips actually understand diseases? We’re gonna end up with a whole new generation of people that have no clue how the shit works to begin with.
Eventually it’ll be like “How do I trim my toenails?”, while the ‘intelligent’ system responds to cut your appendages off.
Granted that AI and quantum computing aren’t quite the same thing. Does it matter? Future generations will have the ability to just ask a computer how to
generatecure a disease…The machine gives no fucks about us, it’ll just as easily destroy us if someone asks the wrong question or enters the wrong formula.
lol.
All of modern technology boils down to math. Curing diseases, building our buildings, roads, cars, even how we do farming these days is all heavily driven by science and math.
Sure, some of modern technology has made people lazy or had other negative impacts, but it’s not a serious argument to say continuing math and science research in general is worthless.
Specifically relating to quantum computing, the first real problems to be solved by quantum computers are likely to be chemistry simulations which can have impact in discovering new medicines or new industrial processes.
Your responses to Herr Dunning-Kruger here were very patient and succinct. I learned from them so thanks for making that effort.
“Let’s use deuterium (stable) instead of tritium (t½ = 12.3y) so our nukes don’t expire in a few years.”
“Will it work?”
“No but it will be stable.”
