Interesting news for quantum doom clock, Craig Kidney, the 2019 author of "How to factor 2048 bit rsa integers in 8 hours using 20 million noisy qubits" just published an update of "with less than a million noisy qubits", on arxiv - That is close to my estimate from January!

Kidney's treatment is, of course, substantially more thorough than the estimates on https://quantumdoomclock.com - but this convergence on estimates is key evidence that the progress is real and accelerating!

Kidney's full article, "How to factor 2048 bit RSA integers with less than a million noisy qubits" is here: https://arxiv.org/pdf/2505.15917

We'll be updating and linking it on quantum doom clock shortly!

Factor of twenty improvement for cracking RSA 2048 over the previous state of the art 🤯😱
