In recent weeks, the same rumor has reached me from unconnected directions: that at least a couple of the companies at the center of quantum cryptanalysis are sitting on results they have chosen not to publish. Nobody offered proof. Nobody could have, for reasons that will become clear. I want to be upfront that this is corridor talk, that I cannot verify a word of it, and that nothing in the argument below depends on it being true. What the whispers did was send me back through the public record of the past few months, looking for whether the story they tell is even plausible. It is, and the verifiable record points in the same direction.

Start with what is public. On March 31, 2026, the two most consequential quantum cryptanalysis papers of the year appeared within hours of each other, and both teams did something that nobody bothered to do for the landmark resource estimates of 2019, 2021, or 2025: they explained why they were publishing at all. Oratomic paired its 10,000-qubit Shor’s paper with a formal responsible disclosure statement. Google consulted the US government before releasing its resource estimates for the 256-bit elliptic curve discrete logarithm problem (ECDLP-256) and locked the underlying circuits inside a zero-knowledge proof. When researchers start justifying the act of publication, the default has already moved.

Both teams acted in good faith, I think, and I covered both results in depth at the time: the Google paper here and the Oratomic paper here. But I read their disclosure statements less as p…
