Just to point it out this isn’t a jab at QC but rather a jab at project 11 and possibly the submission author, basically they failed to validate the submission properly and the code proves that the solution is classical.

Recovering a 17bit ecc key isn’t a challenge for current classical computers via brute force.

[dead]

if the solution is faster than random it could still be a real solution on a quantum computer.

well, it's slower than random

“recovers every reported private key at statistically indistinguishable rates from the IBM hardware runs.”

Did that mean success rate from multiple runs or speed for a single run?
