A Quantum Random Number Generator (QRNG) is a device that generates truly random numbers by leveraging the fundamental principles of quantum mechanics. Unlike classical random number generators (RNGs), which rely on deterministic algorithms or chaotic physical processes, QRNGs extract randomness from inherently unpredictable quantum phenomena.
Random numbers and random number generators find applications in variety of fields starting from pure sciences for modelling statistical processes to social sciences for fair sampling, cryptography or the gaming industry that may be gambling or video games. QRNG provides random numbers which are private to the parties, no one else can have a copy or generate a copy. They are true random number generators which use quantum mechanical processes to generate the sequence of random numbers.
They have future until we have a global quantum information network of connected quantum computers and quantum communication devices. However, they can be easily upgraded to quantum secure communication devices by utilizing physical variables associated with a quantum system.
