Can’t say I’ve programmed it (even with an emulator) but I find it interesting (studied Physics at uni so we covered quantum mechanics but not within the concept of computing).

One cool description I heard once was that quantum computers “borrow processing power from the multiverse” - although I don’t buy the multiverse theory tbh - far too inefficient with processing power.

I can see how people might say that, due to the number of quantum states that seem to dwarf the number of particles in our universe.

When should we worry away SHA-256 being solved by quantum computers? Bearing in mind the quantum tech is probably more advanced than publicly announced.

its weird to me that this is always brought up, we should be worried about ecdsa (maybe), not sha2

🤚 excruse prease ser, why?

Shor’s algorithm speedup can in theory calculate private keys from public keys. I don’t see how grovers search would help much with sha2, and thats not even an interesting attack.

Yeah, that would suck. Didn’t realise that was more susceptible.

Remember Q* and “What did Ilya see?”? With speculation that somehow the maths improvements with AI had somehow worked out P = NP. That would have also sucked.
