Oh, my. IBM is way lower than I thought. Thank you for setting my perception straight; I amended GP accordingly. I would almost qualify that as intellectual self-subjection (and perhaps ethical, in the way of science). Aiming so low that it's trolling, for lack of a better word. Wikipedia's "Quantum supremacy"[1] article: > The term was originally popularized by John Preskill[2] but the concept of a quantum computational advantage, specifically for simulating quantum systems, dates back to Yuri Manin's (1980) and Richard Feynman's (1981) proposals of quantum computing. [1]…

> however, despite other interesting finds in the paper (such as being able to collapse state and read output from multiple qubits at once), claiming quantum supremacy feels to me to be somewhat aggrandising and disingenuous, given what the quantum circuit was actually computing As the person says, they have been out of the field. For better or for worse, this is the term the field settled on years ago to mean showing that a quantum computer can sample from the Porter-Thomas distribution more quickly than a classical computer, “beyond reasonable doubt.” (What I mean by the last bit is that it…

Referring to the point where quantum computers are better at one esoteric thing that's not even useful as a "singularity" is laughably atrociously ridiculous. The actual relevant technical term is "quantum supremacy" [1], which is already misleading (implies complete dominance but actually refers to not being completely dominated). There's no need to make it worse! Also, the theorists didn't "pinpoint" anything. They showed that quantum supremacy via boson sampling was harder than previously thought. They improved the classical simulation algorithm, raising the bar quantum computers will have…
