The linear and nonlinear Jaynes-Cummings model for the multiphoton transition
Abstract
With the Jaynes-Cummings model, we have studied the atom and light field quantum entanglement of multiphoton transition, and researched the effect of initial state superposition coefficient C1, the transition photon number N, the quantum discord δ and the nonlinear coefficient on the quantum entanglement degrees. We have given the quantum entanglement degrees curves with time evolution, and obtained some results, which should have been used in quantum computing and quantum information.
