时空曲率在单量子系统的波函数上引起潮汐力。利用双光脉冲原子干涉仪，我们测量了与这种潮汐力相关的相移。每个干涉仪中的宏观空间叠加态（延伸超过16厘米）充当时空流形的非定域探测器。此外，我们利用双原子干涉仪作为重力梯度计进行精确的重力测量。
Spacetime curvature induces tidal forces on the wave function of a single quantum system. Using a dual light-pulse atom interferometer, we measure a phase shift associated with such tidal forces. The macroscopic spatial superposition state in each interferometer (extending over 16 cm) acts as a nonlocal probe of the spacetime manifold. Additionally, we utilize the dual atom interferometer as a gradiometer for precise gravitational measurements.
