Source-device-independent heterodyne-based quantum random number generator at 17 Gbps.

摘要: Random numbers are commonly used in many different fields, ranging from simulations fundamental science to security applications. In some critical cases, as Bell’s tests and cryptography, the random required be both private provided at an ultra-fast rate. However, practical generators usually considered trusted, but their can compromised case of imperfections or malicious external actions. this work we introduce efficient protocol which guarantees speed generation. We propose a source-device-independent based on generic Positive Operator Valued Measurements then specialize result heterodyne measurements. Furthermore, experimentally implemented protocol, reaching secure generation rate 17.42 Gbit/s, without need initial source randomness. The has been proven for general attacks finite key scenario.
