The Evolution Of Multi-partite Quantum Entanglement In The Cavity QED And Its Applications

Entanglement plays a crucial role in quantum information processing and quantumcomputation. Thus, the dynamics of quantum entanglement in quantum systems attractedmuch attention. Based on the previous results, we will investigate the dynamics of quantumentanglement in several situations. Then, we will discuss some applications of quantumentanglement in quantum information processing.This article can be divided into three chapters. In the first chapter, we review the historyof quantum entanglement concisely; in the second chapter, we review some basic concepts ofquantum entanglement and the applications of the entanglement. In the third chapter, we willdiscuss the multi-partite quantum entanglement in rotating wave approximation, and thendiscuss the evolution of the multi-partite quantum entanglement when the noise and Starkeffect are taken into account.
