Entanglement preservation on two coupled cavities

Abstract

The dynamics of two coupled modes sharing one excitation is considered. A scheme to inhibit the evolution of any initial state in subspace $\{|1_a,0_b>,|0_a,1_b>\}$ is presented. The scheme is based on the unitary interactions with an auxiliary subsystem, and it can be used to preserve the initial entanglement of the system.
