Influence of entanglement degree on squeezing and photon antibunching in the two-photon Jaynes-Cummings model

摘要

We study the interaction of two entangled two-energy-level atoms interacts with a single-mode and two-photon cavity field. The atom state is detected after exiting the cavity, and it is found that the nonclassical properties of the field states depend strongly on the entanglement degree between the two atoms. Meanwhile it is shown that squeezing of field and photon antibunching can be greatly enhanced via selective atomic measurements. [References: 6]
