标题： Complementarity-Entanglement Tradeoff in Quantum Gravity

摘要： 引力的量子化仍然是现代物理学中最重要且极其 elusive 的挑战之一。 任何试图解决这个长期存在的问题的努力似乎都注定会失败，因为获得直接实验证据（即探测引力子）以揭示引力的量子特性的方式远远超出了当前的能力。 最近，人们发现，在干涉框架下精心设计的引力诱导纠缠可以用来见证引力的量子性质。 尽管这些方案提供了研究量子引力的有希望的工具，但这些方案的许多基本和经验方面仍有待发现。 考虑到除了量子纠缠之外，量子不确定性原理和互补性原理是量子物理的另外两个基础方面，引力的量子性质需要表现出所有这些特征。 在这里，我们提出了一种干涉平台，用于测试量子引力背景下的这三个非经典方面，从而在更广泛和更深的背景下连接引力和量子物理。 正如我们在本文中所展示的，量子引力的这三种基本特性都可以在干涉方案中构建并进行全面分析。 显示英文摘要

摘要： Quantization of the gravity remains one of the most important, yet extremely illusive, challenges at the heart of modern physics. Any attempt to resolve this long-standing problem seems to be doomed, as the route to any direct empirical evidence (i.e., detecting gravitons) for shedding light on the quantum aspect of the gravity is far beyond the current capabilities. Recently, it has been discovered that gravitationally-induced entanglement, tailored in the interferometric frameworks, can be used to witness the quantum nature of the gravity. Even though these schemes offer promising tools for investigating quantum gravity, many fundamental and empirical aspects of the schemes are yet to be discovered. Considering the fact that, beside quantum entanglement, quantum uncertainty and complementarity principles are the two other foundational aspects of quantum physics, the quantum nature of the gravity needs to manifest all of these features. Here, we lay out an interferometric platform for testing these three nonclassical aspects of quantum mechanics in quantum gravity setting, which connects gravity and quantum physics in a broader and deeper context. As we show in this work, all of these three fundamental features of quantum gravity can be framed and fully analyzed in an interferometric scheme.
