我们展示了一种在氮化硅微谐振器中使用双抽运简并光学参量振荡器的全光量子随机数发生器。在两个非简并泵浦的正常群速度色散范围内，利用参数四波混频实现了频率简并的双相态输出。我们实现了2 MHz的随机数生成率，并使用国家标准与技术研究所统计测试套件验证了我们输出的随机性。该方案为芯片规模的随机数发生器提供了潜在的机会，产生速率为千兆赫，无需后处理。
We demonstrate an all-optical quantum random number generator using a dual-pumped degenerate optical parametric oscillator in a silicon nitride microresonator. The frequency-degenerate bi-phase state output is realized using parametric four-wave mixing in the normal group-velocity dispersion regime with two nondegenerate pumps. We achieve a random number generation rate of 2 MHz and verify the randomness of our output using the National Institute of Standards and Technology Statistical Test Suite. The scheme offers potential for a chip-scale random number generator with gigahertz generation rates and no postprocessing.
