Quantum Randomness Beacon

Definition

A quantum randomness beacon is a system that publicly broadcasts unpredictable random numbers generated from quantum processes. This beacon uses genuine quantum phenomena, such as photon polarization or radioactive decay, to produce sequences of bits that are inherently unpredictable and verifiable. It provides a shared, unbiased source of randomness that multiple parties can independently access and verify for integrity. Such systems are critical for applications requiring strong, auditable randomness.
