Non-Gaussian entanglement in gravitating masses: the role of cumulants
arXiv:2108.00662 · doi:10.1103/PhysRevD.105.026011
Abstract
We develop an entanglement criterion with third- and fourth-order cumulants to detect the entanglement of non-Gaussian states. The efficiency of the entanglement criterion is investigated for gravitating mirrors in optomechanical systems. We show that the entangled regime of the mirrors is enlarged by the third- and fourth-order cumulants. We also discuss the limitations of the entanglement criterion for mirrors in a highly non-Gaussian state.
