QSMU: Quantum Statistics, Milestones & Updates

A slanted three-dimensional grid of white dots with two points marked by large dots. A bright path joins them in three steps from point to point, and a dim path wanders between them the long way round.

Are you already using post-quantum encryption?

Which browsers and apps already protect you from future quantum computers, how much of the web uses that protection, what is still missing, and why you probably don't need to do anything.

How well does a real quantum computer work?On October 11, 2026 we ran small programs on a real quantum computer. The shortest ones came out right at least 98.8% of the time. Factoring 15 the long way came out right 27.1% of the time, when random guessing would get 25%.We rerun them every month

Q-Day

How close are quantum computers to breaking encryption?Still a long way off, judging by every published estimate of the machine it would take, compared with the machines actually built.
