论文摘要
提出了基于真空波动的测量的无偏见与无源的量子随机数发生器方案，以实现局部振荡器引入的有效消除系统偏置和共同模式噪声。得出最佳参数设置，以避免系统在每个测量中同时记录两个规范共轭二次。特别是，它提供了一种新的方法来研究测量两个相等和不平等强度的四倍体之间的性能差异。实验证明，该系统支持4.2 Gbps无偏差的无源随机数生成，其共同模式拒绝率达到61.17 dB。此外，该方案提供了一种全光学方法，促进了将源无关的量子随机数发生器整合到紧凑的芯片中。
A bias-free source-independent quantum random number generator scheme based on the measurement of vacuum fluctuation is proposed to realize the effective elimination of system bias and common mode noise introduced by the local oscillator. Optimal parameter settings are derived to avoid the system recording two canonically conjugate quadratures simultaneously in each measurement. In particular, it provides a new approach to investigate the performance difference between measuring two quadratures of equal and unequal intensity. It is experimentally demonstrated that the system supports 4.2 Gbps bias-free source-independent random number generation, where its common mode rejection ratio reaches 61.17 dB. Furthermore, the scheme offers an all-optical method facilitating the integration of source-independent quantum random number generators into compact chips.
