We present a high-speed random number generation scheme based on measuring the quantum phase noise of a single-mode laser operating at a low intensity level near the lasing threshold. A delayed self-heterodyning system has been developed to measure the random phase fluctuation. By actively stabilizing the phase of the interferometer, a random number generation rate of 500 Mbit/s has been demonstrated and the generated random numbers have passed all the DIEHARD tests.
我们提出了一种基于测量单模激光在接近激光阈值的低强度水平下的量子相位噪声的高速随机数生成方案。已经开发了延迟自外差系统来测量随机相位波动。通过主动稳定干涉仪的相位，已经演示了 500 Mbit/s 的随机数生成速率，并且生成的随机数通过了所有 DIEHARD 测试。
