标题： Quantum effects in rotating reference frames

摘要： 我们考虑在旋转大质量物体的Kerr度规中相反方向传播的干扰单光子的时间延迟。 经典上，时间延迟表现为相干光源之间的相位差。 在量子力学中，由于干扰光子的不可区分性导致的可见度损失与时间延迟直接相关。 因此，我们可以使用Hong-Ou-Mandel（HOM）凹陷这一纯粹的量子力学效应来观察Kerr框架拖拽效应。 根据爱因斯坦的等效原理，我们可以类比地考虑一个旋转的转盘来模拟Kerr度规。 我们考察了使用光纤进行此类实验的可行性，并注意到二阶色散中的抵消，但群速度存在方向依赖性差异。 然而，对于所选的实验参数，我们可以有效地假设光在真空中传播。 显示英文摘要

摘要： 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.
