Replace IBM Quantum back end with /dev/urandom

pigeons

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.

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.

Quantum computing is 3 decades old scam. Not even Google was able to prove that their quantum computer works LOL. weakened algorithms to the extreme (17 bits in 2026 LOL).

A 17 bit key has 131072 possibilities, which is trivially easy to brute force. Defeating it with a quantum computer is still very much a physics demonstration, and not at all attempting to be a useful computing task.

This was exactly the premise of my sigbovik April Fool's paper in 2025 [1]: for small numbers, Shor's algorithm succeeds quickly when fed random samples. And when your circuit is too long (given the error rate of the quantum computer), the quantum computer imitates a random number generator. So it's trivial to "do the right thing" and succeed for the wrong reason. It's one of the many things that make small factoring/ecdlp cases bad benchmarks for progress in quantum computing. I warned the project11 people that this would happen. That they'd be awarding the bitcoin to whoever best obfuscated that the quantum computer was not contributing (likely including the submitter fooling themselves). I guess they didn't take it to heart. [1]: https://sigbovik.org/2025/proceedings.pdf#page=146
