论文摘要
我们在球形质量的重力场中引入了用于量子开关的方案，并确定其在地球重力中实现所需的时间间隔。用无限顺序进行操作的代理之一是路径叠加态的量子系统。将其适当时间和位置之间的纠缠作为实现量子开关的资源。所提出的协议的实现将探测量子力学对弯曲空间上描述的物理状态，尚未通过实验探索。
We introduce a protocol for a quantum switch in the gravitational field of a spherical mass and determine the time interval required for its realization in the gravity of Earth. One of the agents that perform operations with indefinite order is a quantum system in a path superposition state. Entanglement between its proper time and position is explored as a resource for the implementation of the quantum switch. The realization of the proposed protocol would probe the physical regime described by quantum mechanics on curved spacetimes, which has not yet been explored experimentally.
