Project Eleven just awarded 1 BTC for "the largest quantum attack on ECC to date", a 17-bit elliptic curve key recovered on IBM Quantum hardware. Yuval Adam replaced the quantum computer with /dev/urandom. It still recovers the key.

but does the quantum hardware do it any faster?

Judging by the fact the original code does more classical work than the prg solution, and in more practical terms, the fact it makes network calls, I'd say the quantum-integrated code is a lot slower for this set of problems.

I think that means success rate, not speed.
