Smart Utility Meter Security Takes a Quantum Leap

Quantum computing has found perhaps a surprising new use: utility meters. Quantinuum, a merger between Honeywell Quantum Solutions and Cambridge Quantum that specializes in quantum computing, is helping build quantum-hardened cryptographic keys to secure Honeywell’s smart utility meters. The service, called Quantum Origin, uses quantum computers to generate large random numbers that can protect private information or sensitive grid infrastructure.
