Applications of quantum technologies are rapidly progressing in communications systems implementations. In particular, quantum key distribution (QKD) and quantum random number generation have become key applications for cryptography and physical layer security. Unlike classical cryptography and network security, in QKD, security is ensured by the laws of physics and is, in principle, unbreachable by an interceptor. In particular, peculiar properties and postulates of quantum physics, such as superposition, entanglement, and quantum measurement uncertainty, are exploited to achieve system security. Quantum random number generator (QRNG) is also an important component in the implementation of QKD protocols. Likewise, in QRNG, true randomness (unpredictability using past data and uniformity of statistical distribution) is guaranteed by the laws of quantum physics. In this study, we review prominent aspects of QKD and QRNG, related standards, protocols, and hardware components. Moreover, a comprehensive review of the current QKD protocols and quantum random number generation methods is also presented.
