Researchers certify randomness from a 56-qubit ion processor

Mar 26, 2025

Minzhao Liu and colleagues use Quantinuum's H2-1 processor and supercomputer verification to certify 71,313 bits of entropy. The security analysis covers a restricted class of adversaries and relies on additional assumptions.

Why it matters

The experiment connects random-circuit sampling to a potential application, while its security assumptions and verification cost limit immediate deployment.
