Abstract
We study the evolution of the squeezing quantified by entropy squeezing in an amplitude damping model consisting of N noninteracting qubits coupled to a common reservoir. We demonstrate that even in the Markovian regime the squeezing of considered qubit system can be effectively protected by selecting the number of qubits in reservoir. Especially, the steady squeezing of a qubit system can be obtained for the Markivan and non-Markovian regimes. The corresponding physical mechanism for enhancing the squeezing is also given. We also compare the differences between the considered amplitude damping model and other two types of amplitude damping models for the conditions of squeezing-protection, and find that although one use different methods to improve the squeezing they can be explained by a unified physical mechanism.
