Patent families ordered by priority date.
My patent work focuses on making quantum randomness usable as infrastructure: generation of random numbers from compact photonic devices, transformation of bit streams into usable formats, distribution and metrics of entropy, workload acceleration, and application-level integration for cryptography and computing. Co-inventor across 8 families, with jurisdictions spanning US, EP, CN, and JP.
