Abstract

The problem of the decoherence of two-level atom being put in a thermal reservoir through an external controllable driving field is studied in high -intensity cavity.The non-opposite angle element of two-level atom's reducible density rectangular array is obtained in three photon processes.We discuss the properties of an external driving field when atom's decoherence vanish from sight.

The elimination of the quantum bit's decoherence in a thermal reservoir

Tang Zhi-xiang, Deng-Yu Zhang

Using a two-level atom as a quantum bit, We have studied the decoherent properties of the single quantum bit model in a thermal reservoir and the intensity dependent coupling Jaynes-Cummings model by calculating the non-oposite angle elements of the reduced density matrix of the intraction system,respectively. We also work out the restriction equation that must be satisfied by the external controllable driving field when the decoherence is to be eliminated.
