arXiv admin note: text overlap with arXiv:1404.0821, arXiv:1205.0979 by other authors<br/>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 $C_{1}$, the transition photon number $N$, the quantum discord $��$ 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.<br/>
