I have absolutely no clue about quantum computing, but I remember this from two years ago. Haven't heard anything since. Is this relevant? Does anyone have tho

  Quantum encryption as in the IEEE Spectrum article is not the same thing as quantum computing, which is what the original post is about. So no, not relevant Even so, HN is all about the non-relevant stuff, so I'll give my two bits on quantum encryption, which is that it is dramatically easier than quantum computing for short distances, yet even so its not practical to replace our entire internet such as to enable its use. And until the quantum computers are built, there's no need for it

    > And until the quantum computers are built, there's no need for it. Disagree. One of the coolest things about quantum encryption is that any attempt to eavesdrop a communication is instantly detectable. This is extremely useful for communication between conventional computers.
