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…
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.”
Yea, fuck paywalls, except there isn’t one here. Not sure what you’re on about.

See, this is an example of the bad faith I mentioned above : cherrypicking examples that suit your preconceived ideas, ignoring the truckload of examples, frameworks and code snippets (which you asked for) I provided with a brief search on a free search engine. You have shown no will to communicate in good faith, so I am ending my interaction with you here. Just for the record, this is disrespectful of my time, as well as yours.
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.

Which, to me, kinda defeats the whole purpose. I’m yet to wrap my head around this whole quantum thing.
It’s important to how they operate. The idea is that when you measure the value, it collapses into the right answer.

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

Well yes, quite possibly, through protein behavior modeling. Do some reading !

Your first link is paywalled, fuck that.
