Turning VCSELs' 'nuisance noise' into truly random quantum encryption

Quantum entropy source from Quside

Quside says its quantum entropy source shows that fast, verifiable quantum entropy can be mass manufactured and embedded at scale (Image: Quside)

By deliberately exploiting the polarisation instability of commercial-grade VCSELs, Quside and Coherent have developed a quantum random number generator that verifies entropy quality from first principles, opening a scalable path to hardware-level cryptographic security
