The ability to generate random numbers is essential to encrypting data. However, any classical method of producing randomness will fundamentally be deterministic – and theoretically predictable. This creates an opportunity for non-deterministic, high entropy quantum random number generators (QRNGs). In this article, IDTechEx explores the opportunities and challenges for QRNG in the growing connected devices and quantum communications markets. High volume deployment needs chip-scale solutions  Quantum technology is often associated with large-scale bulky laboratory equipment, supported...
