Entanglement and decoherence of massive particles due to gravity
Daisuke Miki, Akira Matsumura, Kazuhiro Yamamoto
Abstract
We analyze the dynamics of a gravity-induced entanglement for $N$ massive particles. Considering the linear configuration of these particles, we investigate the entanglement between a specific pair of particles under the influence of the gravitational interaction between the massive particles. As the particle number increases, the specific particle pair decoheres more easily due to the gravitational interaction with other particles. The timescale of the gravity-induced decoherence is analytically determined. We also discuss the entanglement dynamics of initially entangled particles, which exemplify the monogamy of the gravity-induced entanglement.
