Random Number Generation from a Quantum Tunnelling Diode.

Random number generation is important in many activities such as communication, encryption, science, gambling, finance, and decision-making. Quality of random numbers is critical in some applications, especially in cryptography, which require true randomness. In this work, we propose exploitation of a commercially-available quantum tunnelling diode as a source of true randomness. This off-the-shelf device is inexpensive and has a promising capability for future electronic integration at large-scale production.
