Abstract

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).

Deng-Yu Zhang

The coherence of two-level atom in a thermal radiation field without rotating wave approximation through an external controllable driving field was investigated. The time evolution properties of non-opposite angle element of two-level atom's reducible density rectangular array was discussed.
