Quantum Entanglement And Entropy Squeezing Of The Atoms In The T-C Model

Quantum entanglement and entropy squeezing of theory are contents of quan-tum optics and quantum information science. Preparation of atomic entangled states and squeezed states is an important application subject in quantum optics and quantum information processing. In this thesis, dynamics of two-atom en-tanglement and of properties of one-atom squeezing in the T-C model are studied by using the theory of quantum entanglement and entropy squeezing, which has great theoric significance and reference value for application. The main points of this thesis are as follows:In the first chapter, we introduce the basic theories associated with this article, including theory of quantum entanglement, and theory of entropy squeezing.In the second chapter. The T-C model is introduced and exact solutions in different conditions in obtained. We also obtained the evolution operator matrix,which made lays the groundwork for subsequent work.In the third chapter, we study dynamical behavior of entanglement of two atoms and entropy squeezing of single-atom in the T-C model。the results that both entanglement dynamics between two atoms and single-atom entropy squeez-ing depend on the initial state of two atoms and the photon number of field stateThe article is ended with a concluding remark and open questions in the fourth chapter.
