In spite of the large astronomical evidence for its effects, the nature of dark matter remains enigmatic. Particles that interact only, or almost only, gravitationally, in particular with masses around the Planck mass—the fundamental scale of quantum gravity—are intriguing candidates. Here, we show that there is a theoretical possibility to directly detect such particles using highly sensitive gravity-mediated quantum phase shifts. In particular, we illustrate a protocol utilizing Josephson junctions.

利用量子干涉检测普朗克尺度暗物质

尽管有大量天文学证据证明暗物质的影响，但暗物质的本质仍然是个谜。仅或几乎仅通过引力相互作用的粒子，特别是与普朗克质量（量子引力的基本尺度）周围的质量相互作用的粒子是有趣的候选者。在这里，我们表明，理论上有可能利用高度灵敏的重力介导的量子相移来直接检测此类粒子。我们特别说明了利用约瑟夫森结的协议。
