A 2-Gbps low-SWaP quantum random number generator with photonic integrated circuits for satellite applications [PDF]

npj Quantum Information
We introduce a low size, weight and power quantum random number generator (QRNG) utilizing compact integrated photonic asymmetric Mach-Zehnder interferometers (AMZIs). Our QRNG is based on phase-diffusion in two gain-switched lasers interfered within two

6 Gbps real-time optical quantum random number generator based on vacuum fluctuation

Review of Scientific Instruments, 2019
We demonstrate a 6 Gbps real-time optical quantum random number generator by measuring vacuum fluctuation. To address the common problem that speed gap exists between fast randomness generation and slow randomness extraction in most high-speed real-time ...

Self-Testing Quantum Random Number Generator [PDF]

Physical Review Letters, 2015
The generation of random numbers is a task of paramount importance in modern science. A central problem for both classical and quantum randomness generation is to estimate the entropy of the data generated by a given device. Here we present a protocol for self-testing quantum random number generation, in which the user can monitor the entropy in real ...
