Quantum Mechanics Delivers Truly Random Numbers On Demand
2025-06-16
Researchers at NIST and the University of Colorado Boulder have created CURBy, a public randomness beacon leveraging quantum entanglement. This system uses a Bell test to measure entangled photons, generating unpredictable, truly random numbers. Unlike classical pseudorandom number generators, CURBy's randomness is traceable and verifiable, secured by the Twine protocol for transparency and security. It provides a reliable source of randomness for applications like audits and lotteries. This breakthrough represents significant progress in applying quantum mechanics, establishing the first public random number service based on quantum nonlocality.
