虽然量子物理学在惯性参照系（平坦时空）中已经被很好地理解，但目前的挑战是寻找非惯性系中量子系统的非平凡或意外行为的实验证据。在这里，我们提出了一个新的测试量子力学在一个非惯性参考系：我们考虑Hong-Ou-Mandel（HOM）干涉在一个旋转的平台上，并研究均匀旋转的影响的光子的可分辨性。理论和实验都表明，旋转运动引起的光子到达时间在出口分束器的相对延迟，并观察到这种延迟作为一个移动的HOM倾角的位置。这个实验可以扩展到使用地球轨道上的卫星对量子物理进行全面的广义相对论测试，并指出了一条使用光子技术在相对论界面上研究量子力学的新途径。
Although quantum physics is well understood in inertial reference frames (flat spacetime), a current challenge is the search for experimental evidence of nontrivial or unexpected behavior of quantum systems in noninertial frames. Here, we present a novel test of quantum mechanics in a noninertial reference frame: we consider Hong-Ou-Mandel (HOM) interference on a rotating platform and study the effect of uniform rotation on the distinguishability of the photons. Both theory and experiments show that the rotational motion induces a relative delay in the photon arrival times at the exit beam splitter and that this delay is observed as a shift in the position of the HOM dip. This experiment can be extended to a full general relativistic test of quantum physics using satellites in Earth's orbit and indicates a new route toward the use of photonic technologies for investigating quantum mechanics at the interface with relativity.
