    Or asked differently.

    What speed-up could a N-qubit quantum computer give
    to this problem, find a positive integer tripple (x,y,z) such that:

    x^3 + y^3 + 42 = z^3

    classical = non-quantum
    non-classical = quantum

    Lets say you don't trust what a quantum computer
    finds as a tripple for (x,y,z) to satisfy:

    x^3 + y^3 + 42 = z^3

    You could then view it as a candidate triple
    only, and still feed it into a normal computer

    and see whether it is a solution. Kind of combining
    approximate search with exact verification.

    And? Who cares? As long as the wave function collapse is
    inside a certain error range, you can read off your qubit.

    Scaling Qubit Readout with Hardware Efficient Machine Learning Architectures >> Reading a qubit is a fundamental operation in quantum computing.
    It translates quantum information into classical information
    enabling subsequent classification to assign the qubit states ‘0’ or
    ‘1’. Unfortunately, qubit readout is one of the most error-prone
    and slowest operations on a superconducting quantum processor.
    On state-of-the-art superconducting quantum processors, readout
    errors can range from 1-10%. These errors occur for various reasons
    – crosstalk, spontaneous state transitions, and excitation caused by
    the readout pulse. The error-prone nature of readout has resulted
    in significant research to design better discriminators to achieve
    higher qubit-readout accuracies. High readout accuracy is essential
    for enabling high fidelity for near-term noisy quantum computers
    and error-corrected quantum computers of the future

    Ernst Specker was very creative. Did he create
    the word “Infuturabilien”? It seems so:

    “In a certain sense the scholastic speculations
    about the “Infuturabilien” [this term invented by
    Specker is to be translated as something like
    ‘future contingencies’] also belong here, that is,
    the question whether the omniscience of God
    also extends to events that would have occurred
    in case something would have happened that
    did not happen. (cf. e.g. [3], Vol. 3, p. 363.)” https://ar5iv.labs.arxiv.org/html/1712.06448

    I guess he was just once again fooling around.
    But the above arxiv link is interesting,
    since one finds his famous riddle, that he

    used in class to motivate young students,
    not behind a paywall, but as a HTML:

    P.S.: But later I was reading a little bit about
    wave function collapse and at the same time generative
    AI, such as scribble diffusion started to blossom:

    Guess whats behind it? But recently wave function collapse
