Spectrum of Entanglement Fluctuations from the Two-Mode Squeezed Cavity Photons

Abstract

We analyze the spectrum of entanglement fluctuations and local entanglement that holds true for the two-mode photon system. We also present a definition for the degree of local entanglement. In order to carry out our analysis, we consider a quantum system with a Gaussian variable with zero mean. It is found that 50% maximum degree of entanglement as well as 75% maximum degree of squeezing occurs at steadystate and threshold in the given frequency interval.
