Abstract

We present the theory, architecture, and performance characteristics of a quantum random number generator (QRNG) which operates in a PCI express form factor-compatible plug-and-play design. The QRNG relies on a thermal light source (in this case, amplified spontaneous emission), which exhibits photon bunching according to the Bose-Einstein (BE) statistics. We demonstrate that 98.7% of the unprocessed random bit stream min-entropy is traceable to the BE (quantum) signal. The classical component is then removed using a non-reuse shift-XOR protocol, and the final random numbers are generated at a 200 Mbps rate and shown to pass the statistical randomness test suites FIPS 140-2, Alphabit, SmallCrush, DIEHARD, and Rabbit of the TestU01 library.

摘要

我们介绍了一种量子随机数发生器（QRNG）的理论、架构和性能特征，该发生器采用与PCI Express外形尺寸兼容的即插即用设计。该QRNG依赖于热光源（在这种情况下为放大自发辐射），根据玻色 - 爱因斯坦（BE）统计呈现光子聚束现象。我们证明，未处理的随机比特流中98.7%的最小熵可追溯到BE（量子）信号。然后使用非重用移位异或协议去除经典分量，最终以200 Mbps的速率生成随机数，并显示通过了TestU01库的统计随机性测试套件FIPS 140 - 2、Alphabit、SmallCrush、DIEHARD和Rabbit。
