• Abstract: In spite or the large astronomical evidence for its existence, 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 in 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 consider a protocol utilizing Josephson junctions.

  The purpose of this study is to deepen our understanding of the phenomenon of quantum superposition of gravitational fields. We consider a trade-off relation of entanglement in a tripartite system consisting of two massive particles and a gravitational field that may be entangled with each other. Our results may help understand the relationship between the quantization of the gravitational field and the meaning of the quantum superposition of the gravitational field.
