论文摘要
最近，人们对桌面实验引起了极大的兴趣，该实验旨在通过证明可以诱导纠缠来表现出重力的量子性质。 We argue that these experiments also provide new information about the interpretation of quantum mechanics: under appropriate assumptions, $ψ$-complete interpretations will generally predict that these experiments will have a positive result, $ψ$-nonphysical interpretations predict that these experiments will not have a positive result, and for $ψ$-supplemented models there may be arguments for either outcome.我们建议这些实验的积极结果将排除一类量子重力模型，这些模型我们称为$ψ$分配的量子重力（PIQG） - 即量子力学与重力之间相互作用的模型，其中重力与非量子偶联而不是量子。我们回顾了一些现有的PIQG模型，并考虑需要做些什么才能使这类方法更具吸引力，最后我们讨论了一种宇宙学现象，该现象可以被视为为PIQG模型提供证据。
Recently there has been a great deal of interest in tabletop experiments intended to exhibit the quantum nature of gravity by demonstrating that it can induce entanglement. We argue that these experiments also provide new information about the interpretation of quantum mechanics: under appropriate assumptions, $ψ$-complete interpretations will generally predict that these experiments will have a positive result, $ψ$-nonphysical interpretations predict that these experiments will not have a positive result, and for $ψ$-supplemented models there may be arguments for either outcome. We suggest that a positive outcome to these experimenst would rule out a class of quantum gravity models that we refer to as $ψ$-incomplete quantum gravity (PIQG) - i.e. models of the interaction between quantum mechanics and gravity in which gravity is coupled to non-quantum beables rather than quantum beables. We review some existing PIQG models and consider what more needs to be done to make these sorts of approaches more appealing, and finally we discuss a cosmological phenomenon which could be regarded as providing evidence for PIQG models.
