Entanglement and decoherence of massive particles due to gravity

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.

Automated summary

The research focuses on the gravity-induced entanglement dynamics of N massive particles, showing that with an increase in particle number, specific particle pairs decohere more easily. The timescale of gravity-induced decoherence and the monogamy of entangled particles were also discussed.
