论文摘要
我们考虑干扰单个光子以旋转巨大物体的Kerr度量相反的时间延迟。从经典上讲，时间延迟显示为相干光源之间的相位差。在量子力学中，由于干扰光子没有区别性而导致的可见性丧失与时间延迟直接相关。因此，我们可以使用Hong-Ou-Mandel（HOM）DIP（纯粹的量子机械效应）观察Kerr框架拖拉效应。根据爱因斯坦的等效原理，我们可以类似地考虑旋转转盘来模拟Kerr公制。我们查看使用光纤的实验的可行性，并注意二阶分散体中的取消，但在组速度上依赖方向依赖性差异。但是，对于所选的实验参数，我们可以有效地假设通过真空传播的光。
We consider the time delay of interfering single photons oppositely traveling in the Kerr metric of a rotating massive object. Classically, the time delay shows up as a phase difference between coherent sources of light. In quantum mechanics, the loss in visibility due to the indistinguishability of interfering photons is directly related to the time delay. We can thus observe the Kerr frame-dragging effect using the Hong-Ou-Mandel (HOM) dip, a purely quantum mechanical effect. By Einstein's equivalence principle, we can analogously consider a rotating turntable to simulate the Kerr metric. We look at the feasibility of such an experiment using optical fibre, and note a cancellation in the second-order dispersion but a direction-dependent difference in group velocity. However, for the chosen experimental parameters, we can effectively assume light propagating through a vacuum.
