The study investigated the effects of noise on quantum coherence and quantum entanglement in quantum information through the interaction between an atomic system described by a two or three-level particle and quantized radiation field, which can have one or two modes and that system is coupled to reservoir. The entanglement in the interacting system of a single mode thermal field and a single qubit with dissipation in the dispersive limit was investigated. The effects of thermal photons on entanglement and coherence loss were investigated. It has been found that, the field is inhibited from...
