摘要:

我们通过实验演示了一种全光随机数生成器,其基础是相干驱动 Kerr 谐振器中的自发对称性破缺。通过反复调节控制参数,使其越过对称性破缺分岔,系统会在两个可能的稳态之间进行随机选择,由此生成随机比特序列。实验在光纤环形谐振器中进行,其中两个对称性破缺后的稳态与正交偏振模式相关联。借助最近发现的自对称化现象,由系统不对称导致的有害偏置被完全抑制;该现象确保对称性破缺像无偏掷硬币一样,在两个可用稳态之间作出真正随机的选择。我们在不进行后处理的情况下,以超过 3 MHz 的速率通过光学方式生成比特,并使用美国国家标准与技术研究院(NIST)和 Dieharder 统计测试套件验证了其随机性。

英文摘要:

We experimentally demonstrate an all-optical random number generator based on spontaneous symmetry breaking in a coherently-driven Kerr resonator. Random bit sequences are generated by repeatedly tuning a control parameter across a symmetry-breaking bifurcation that enacts random selection between two possible steady-states of the system. Experiments are performed in a fibre ring resonator, where the two symmetry-broken steady-states are associated with orthogonal polarization modes. Detrimental biases due to system asymmetries are completely suppressed by leveraging a recently-discovered self-symmetrization phenomenon that ensures the symmetry breaking acts as an unbiased coin toss, with a genuinely random selection between the two available steady-states. We optically generate bits at a rate of over 3~MHz without post-processing and verify their randomness using the National Institute of Standards and Technology and Dieharder statistical test suites.
