Decoherence Properties of a Two-level Atom in Degenerate Two-photon Processes with a Kerr-like Medium

两能级原子被嵌制在充满类 Kerr介质的热辐射场 (热库 )中 ,通过分析两能级原子约化密度算符非对角元的时间演化 ,研究简并双光子过程中原子在类

The two level atom is put in a thermal radiation field with a Kerr like medium.The time evolution properties of non opposite angle element of two level atoms reducible density rectangular array is discussed.Decoherence properties of two level atoms quantum bit is studied in degenerate two photon processes when the two level atom interacts with the external environment (Kerr like medium and thermal reservoir).
