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.
I think there is potential in it but it is absolutely going to become the next stock market slop after AI goes bust. You'll see everyone and their mom significantly overpaying for $10 billion random noise generators.
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.
You wrote that? Nice piece of work! Came here to post exactly this, that's the sigbovik paper in practice.
I'm still waiting for the Quantum Bogosort version of this "factorisation". For those not familiar with the algorithm, it relies on the many-worlds interpretation and is:
Shuffle the list randomly
If the list is sorted, stop
If it isn’t sorted, destroy the entire universe
Adaptation of this algorithm to factorisation is left as a homework exercise for the student.
Pasting my comment from the other article here - curious to understand the degree to which I'm understanding this.

The article itself is maddeningly vague on exactly what happened here.
At first blush, it looks like the quantum computer was just used to generate random noise? Which was then checked to see if it was the private key? Surely that can't be.
The github README [0] is quite extensive, and I'm not able to parse the particulars of all the sections myself without more research. One thing that caught my eye: "The key insight is that Shor's post-processing is robust to noise in a way that raw bitstring analysis is not."
"This result sits between the classical noise floor and the theoretical quantum advantage regime. At larger curve sizes where n >> shots, the noise baseline drops below 1% and any successful key recovery becomes strong evidence of quantum computation."
So... is one of the main assertions here simply that quantum noise fed into Shor's algorithm results in requiring meaningfully fewer "shots" (this is the word used in the README) to find the secret?
Someone help me understand all this. Unless I'm missing something big, I'm not sure I'm ready to call this an advancement toward Q-Day in any real-world sense.
"quantum grifting" has hit the cryptocurrency space brutally.
Scammers can take an old defunct coin or create a new one, buy up/create supply, strap ML-DSA on to it, and pump their shitcoin claiming it's quantum safe, then they can unload.
Eventually low information retail will get wise to this, I honestly don't know who this even works on right now.
They are missing the point though. The point is not even to be faster but to show that the QC is QCing. It can be slower than random search, and in fact might be expected to be. It’s kind of like early fusion plasma experiments that required vastly more energy than you got from fusion.
We are still doing science and engineering experiments, not making production anything.
"dequantization" is a thing and it's a very legitimate part of quantum information research. It's useful to probe if something was truly quantum or just smokes and mirrors, because it helps us understand where the boundary between quantum and classical lies. Another dequantized result from the past days: https://arxiv.org/abs/2604.21908
The person who won the challenge with this apparently misleading code seems to have absolutely no quantum computing background. He writes this as background about himself:
