back to article IBM asks UChicago, UTokyo for help building a 100K qubit quantum supercomputer

IBM plans spend $100 million to build a 100,000 qubit "quantum-centric supercomputer" allegedly capable of solving the world's most intractable problems by 2033 and it's tapped the Universities of Tokyo and Chicago for help. Quantum computing today is a bit of a catch-22. The jury is still out as to whether the tech will ever …

      Err ... we have quantum computing today. We might have quantum advantage today, e.g. in Google's quantum-circuit experiments.

      If you had written "useful quantum computing to be 10 years away..." you might have been right, though there's a decent chance that one or another of the systems under development will eventually scale up to a number of error-corrected qubits that is actually useful for physical-simulation tasks.

    ...whether the tech will ever amount to anything more than a curiosity...

    It's in a superposition of just a curiosity and more than a curiosity.

      "It's in a superposition of just a curiosity and more than a curiosity."

      more like:

      A superposition of 'Almost impossible to achieve' and 'Almost possible to achieve' ..... that is an awful lot of 'Almost' by any measure !!!

    Let's band all the current hype together then

    What with qbits being so small and quantumish

    They do seem to need an awful lot of infrastructure around them.

    Well, this bit is nonsense

    From the article: a 100,000 qubit "quantum-centric supercomputer" allegedly capable of solving the world's most intractable problems

    Did IBM actually claim that? Because it's prima facie bullshit.

    There are only a handful of areas in which we know of algorithms that have a quantum advantage – i.e. are in complexity class BQP (or possibly some related classes; see the Complexity Zoo). They most certainly do not cover most of "the world's most intractable problems".
