相对论和量子力学的统一是当代物理学长期面临的挑战。量子光学的实验技术直到最近才达到研究非惯性运动影响下的量子系统所需的成熟度，例如在引力场中保持静止，或受到均匀加速度。在这里，我们报告的实验中，一个真正的量子态的纠缠光子对暴露于一系列不同的加速度。我们测量的纠缠见证的g值范围从30毫克到高达30克自由落体以及在旋转离心机，从而得出了一个上限的均匀加速度对光子纠缠的影响。相对论和量子力学的统一是物理学中一个长期存在的挑战。在这里，作者研究了大范围的加速度对纠缠光子对的影响，为非惯性系对量子系统的影响提供了一个上限。
The unification of the theory of relativity and quantum mechanics is a long-standing challenge in contemporary physics. Experimental techniques in quantum optics have only recently reached the maturity required for the investigation of quantum systems under the influence of non-inertial motion, such as being held at rest in gravitational fields, or subjected to uniform accelerations. Here, we report on experiments in which a genuine quantum state of an entangled photon pair is exposed to a series of different accelerations. We measure an entanglement witness for g-values ranging from 30 mg to up to 30 g—under free-fall as well on a spinning centrifuge—and have thus derived an upper bound on the effects of uniform acceleration on photonic entanglement. The unification of the theory of relativity and quantum mechanics is a long-standing challenge in physics. Here the authors investigate the effects of a wide range of accelerations on an entangled photon pair, providing an upper bound for the effects of non-inertial frames on quantum systems.
