IBM Claims Quantum Computing Breakthrough (axios.com) 79

Axios reports: IBM has created a quantum processor able to process information so complex the work can't be done or simulated on a traditional computer, CEO Arvind Krishna told "Axios on HBO" ahead of a planned announcement.

Why it matters: Quantum computing could help address problems that are too challenging for even today's most powerful supercomputers, such as figuring out how to make better batteries or sequester carbon emissions.

Driving the news: IBM says its new Eagle processor can handle 127 qubits, a measure of quantum computing power. In topping 100 qubits, IBM says it has reached a milestone that allows quantum to surpass the power of a traditional computer. "It is impossible to simulate it on something else, which implies it's more powerful than anything else," Krishna told "Axios on HBO...."

Krishna says the quantum computing push is one part of his approach to return the company to growth.

"Some people think of it as science fiction," Krishna says of quantum computing in a preview clip from the Axios interview. "I think of it now as a feat of engineering."

    This is the third Quantum Computing BS story today. IBM literally "simulates" a quantum circuit and then claims it is superior to classical. Well, no shit sherlock. As I said before this is the equivalent of claiming a pebble tossed in water is super to a classical computer because it accurately and instantly shows the interference and refraction patterns. There you go, call it "pebble supremacy." Or a camera and flash photography setup is superior to a classical computer in rendering photorealistic ray-tracing. Technically yes, but in reality bullshit.

      There is a very easy way to prove actual quantum supremacy on a true quantum computer (ie, one without faux-qubits) .. factorize the product of two large randomly chosen prime numbers faster than GFNS. Someone call me when they do that.

          Maybe they already did, and we're only seeing the BS stuff...

        • There haven't been any meaningful achievements yet, why worry about more meaningless achievements?

      • But quantum supremacy must already be here, it's been announced at least a dozen times already just this year alone. Next year I expect at least two dozen announcements.

        And you can tell it's quantum because all of those announcements claimed that they were the first to achieve quantum supremacy, and all the future ones will also all be the first to achieve quantum supremacy. Something to do with quantum superposition of quantum supremacy announcements I believe.

        Not going to happen for bit-length that matter anytime soon and maybe never. QCs do not scale. Even the claimed 127 qbits (probably ~50 or so after error correction) took excessive effort and 50 years of research. If things continue to scale this badly, they will maybe be at 256 qbits (and 80 effective or so) in another 50 years. My programmable pocket calculator from 30 years back has more computing power.

        For a little perspective, executing Shor's algorithm to do the task you're requesting requires 2n + 3 qubits for every bit of the large semi-prime to be factored. For the 2048 bit modulus commonly used today in RSA-2048, the machine requires 4099 qubits to perform the factorization in "push the button, get the answer" time. And not just any 4099 qubits. All 4099 of them must be successfully generated fully coherently. That is, every single bit must be quantumly entangled. (Although now I'm reading that

      Huh, I'd always wondered how it worked, I think you've finally made me understand. Thanks, because the news items have all been entirely useless for all these years.

      I presume then the idea is it's like an analogue computer of old where they electrically simulated the desired maths with intertwined op-amps and passive tuning elements (resistors/capacitors/inductors), and the results could be viewed with an oscilloscope.

      • Here is the link to the paper on how their previous quantum supremacy claim worked (with 53 bits instead of 127): https://www.nature.com/article... [nature.com]

      • If you think it's obvious now then you definitely don't know what's going on. It's superposition and other weird magical quantum shit that pretty much defies understanding but appears to be the way the universe works.

          Quantum behaviour wasn't the question. The question answered is one of how it applies to computing. Something I'd never seen answered in a single sentence like that before. For that, I thank backslashdot's comment.

          • You can't separate "quantum behavior" from quantum computing. If you think you've got it straight, or that OP described it accurately, you're probably wrong.

              Analogue computers are nothing like a digital computer. Maybe that's where the disconnect in this conversation is. I guess there are so very few in the media that would know what one is that they'd never use it as the reference. That adds up.

      But the summary says it will help to sequester carbon. That must be true because IBM would never spew BS about something as important as sequestering carbon and the relevance of quantum computing to carbon sequestration is totally obvious to everyone.

          Well, it sorta is, and sorta isn't. It highlights the problem of cross domain language and reporting. Domain specific terms can have precise meaning, but through reporting it hits the popular meaning and people forget that the two domains are not using it the same way. I guess the key word here is languages, rather than language.. we are talking about what are essentially two dialects of english and people reading a story written in one and read in another.

      Not really. Take a linear algebra course first. There is no way to simplify it without making it wrong -- but I will try. Do you know what an interference pattern is? Well in a quantum computer, you create a circuit through which a special kind of interference pattern occurs. The magic is that you create parallel interference patterns (think of it as the same computation occurring with slightly different settings across multiple universes in parallel ultimately affecting the interference pattern in your universe.) The resulting pattern will tell you the answer to certain types of problems. Problems that can be mapped such that they affect the interference pattern. Specifically, ones that can utilize quantum Fourier transform or amplitude amplification.
