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.
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 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.
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.
The point here is that the quantum computer component of the original solution is not doing anything - that the algorithm being run overall is not actually a quantum algorithm, but a classical probabilistic algorithm.
If the quantum computer were a key component of the solution, replacing it with an RNG would have either no longer yielded the right result, or at least would have taken longer to converge to the right result. Instead, the author shows that it runs exactly the same, proving all of the relevant logic was in the classical side and the QC was only contributing noise.
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.
You know you're blowing your reputation when such claims are met by scientific articles with the headline, "Google claims 'quantum advantage' again." [1]
Dont they report an advantage based on simulating quantum effects every other year? I was promissed a quick way to decrypt my old harddrives decades ago, can we have that at some point before the sun burns out?
I expect they're just banking on getting their investment back with some fat returns by licensing it to the NSA to decrypt their hoovered up encrypted coms, with their data storage now reaching up to the yottabyte level. That's a lotta byte.
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.
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.
QC relies on the observed output being statistically significant. This rebuttal is pointing out that Project Eleven only ran the algorithm once. At this point, there is no proof the IBM QC platform is generating anything statistically significant, especially more significant than the performance of feeding it /dev/urandom.
Basically, there is no proof this was real quantum computing instead of random noise picked up by the hardware inside the QC.
Now to show that the QC is doing anything against this rebuttal, they have it run it a significant number of times and show that it breaks the key a larger amount of times than feeding it a uniform distributed random noise source like /dev/urandom.
Imagine investing trillions of dollars on slightly worse random numbers. I suppose it's a better use of money than DEI hiring and political correctness initiatives. At least random numbers don't destroy society systematically.

but does the quantum hardware do it any faster?
> The author's own CLI recovers every reported private key at statistically indistinguishable rates from the IBM hardware runs.
I think that means success rate, not speed.

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?
Truly an unfortunate thumbnail crop for this story: https://image.non.io/b3f69546-aeb3-48c3-a76d-723f29b28f48.we...
Not sure if we're looking at the same thing, but surely that's the 't' in 'quan(tumslop)'?
Yes, but the t looks like a c, making it read like a "slop" of a sexual bodily fluid.

But if the QC’s contribution is indistinguishable from that of a random number generator, then what is being demonstrated?
Perhaps I'm ignorant, but isn't the idea that you can do it faster than brute force?
If the results are statistically identical to guessing then it seems like you've just built a Rube Goldberg contraption.
does the number of calls to "QM" match between the implementations?

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).
Didn't Google recently report a verifiable quantum advantage?

Are your old hard drives encrypted using asymmetric cryptography? If not, I'm not sure who made you that promise.
The funny thing is we already have PQC so even if quantum computing works, it will be immediately irrelevant.
At least for breaking crypto, which seems to be its headline feature. Maybe there are other useful things it can do?

On what? They can't run it against anything real
