论文摘要
我们提出了一个普遍的论点,以表明如果物理系统可以在两个量子系统之间进行局部产生,那么它本身必须是非古典的。值得注意的是,我们不假设任何古典或量子形式主义来描述介导的物理系统:我们的结果取决于一般信息理论原理,源自最近提出的构造者信息理论。该论点为最近提出的重力测试提供了必不可少的理论基础,这是基于量子探针中重力诱导的纠缠的重力测试。
We propose a general argument to show that if a physical system can mediate locally the generation of entanglement between two quantum systems, then it itself must be non-classical. Remarkably, we do not assume any classical or quantum formalism to describe the mediating physical system: our result follows from general information-theoretic principles, drawn from the recently proposed constructor theory of information. This argument provides the indispensable theoretical basis for recently proposed tests of non-classicality in gravity, based on witnessing gravitationally-induced entanglement in quantum probes.
