The entanglement evolution of the quantum optical systems
Abstract
Abstract In this paper, we apply the Thermofield Dynamics (TFD) method to transform a quantum optical master equation into a Schrödinger-like equation for an arbitrary initial condition, making it a preferred approach for solving open quantum system problems. Entanglement and quantum mutual information are analyzed for each case using the symplectic eigenvalues of the corresponding covariance matrix, followed by two-mode and single-mode squeezed states.
