Xiaoping Li · Journal of Jiangxi Normal University · 2004
We present a measure for generating entangled state of atom-cavity field, which is prepared based on the two-photon Jaynes-Cummings model of atom-cavity field interaction. Through changing the interaction time, the degree of entanglement of the atom-cavity field hasa periodic change. It is shown that the quantum entanglement state will stay in the maximally entangled state for a long time when the detuning is equal to Rabi frequency.
