Quantum Random Number Generator

Primary definition

A Quantum Random Number Generator (QRNG) is a device that produces truly random numbers by measuring unpredictable quantum mechanical processes, such as photon arrival times or vacuum fluctuations, rather than using algorithms. Unlike pseudo-random generators, QRNGs provide foundational, non-deterministic security for cryptography, IoT devices, and simulations, ensuring keys are fundamentally unpredictable.
