论文摘要
我们重新审视Bose-Marletto-dedral（BMV）桌面实验提案 - 旨在使用重力介导的纠缠见证量子重力 - 分析位置在实验中的作用。我们首先对物质和重力的相互作用进行完全量子建模，然后在BMV实验中的重力介导的纠缠范围内显示，而无需吸引重力场的量子自由度。我们讨论需要采取哪些假设来将当前的BMV实验提案解释为量子重力的证明，并确定了类似BMV的实验可以作为量子重力的证明而不必假设重力场中存在局部介体的修改。
We revisit the Bose-Marletto-Vedral (BMV) table-top experimental proposal - which aims to witness quantum gravity using gravity mediated entanglement - analyzing the role of locality in the experiment. We first carry out a fully quantum modelling of the interaction of matter and gravity and then show in what way gravity mediated entanglement in the BMV experiment could be accounted for without appealing to quantum degrees of freedom of the gravitational field. We discuss what assumptions are needed in order to interpret the current BMV experiment proposals as a proof of quantum gravity, and also identify the modifications that a BMV-like experiment could have in order to serve as proof of quantum gravity without having to assume the existence of a local mediators in the gravitational field.
