    So does this mean that asymmetric encryption is officially breakable?

      For the coming years I doubt it. These research systems so far can only demonstrate some benchmarks according to which “Quantum Supremacy” is achievable in principle. I think a popular science article would mention the encryption breaking part explicitly. I don’t know what the current state of the art is, but if an article mentions something in relation to “Shor’s algorithm” then pre quantum encryption would be pretty much about to die.

        You wouldn’t know at all. The point of having an encryption breaker is that you don’t tell everyone you have it and simply read all their secrets at your leisure.

        What you would do is tell someone that your latest record is actually something you can do with ease and appear weaker than you are.

        Because there is always someone on the internet looking to sound intelligent by supporting the narrative that sounds like the one most will accept.

        Superiority of thought through popularity of opinion.

        All encryption has been broken for years. P v. NP has been solved.
