论文摘要
爱因斯坦等效原理基于引力质量和惯性质量的平等,这导致了自由陷入概念的普遍性。到目前为止,该原则经过了很好的测试,并以非常精确的方式进行了测试。但是,所有这些测试和相应的参数均基于经典设置,在该设置中,质量的位置和速度概念与经典价值相关,而不是量子实体。在这里,我们将提供一个简单的协议,基于在实验室中创建大型空间叠加状态,以测试等效原理的完全量子制度,在该原理中,物质和重力都在PAR处于量子实体。我们将认为,这种量子方案在测试方面是独一无二的,特别是通过见证量子纠缠对弱等效原理的概括。
The Einstein equivalence principle is based on the equality of gravitational mass and inertial mass, which has led to the universality of a free-fall concept. The principle has been extremely well tested so far and has been tested with a great precision. However, all these tests and the corresponding arguments are based on a classical setup where the notion of position and velocity of the mass is associated with a classical value as opposed to the quantum entities. Here, we will provide a simple protocol based on creating large spatial superposition states in a laboratory to test the fully quantum regime of the equivalence principle where both matter and gravity are treated at par as a quantum entity. We will argue that such a quantum protocol is unique with regard to testing especially the generalization of the weak equivalence principle via witnessing quantum entanglement.
