Generation of atomic entangled states with selective resonant interaction in cavity quantum electrodynamics
Yun‐Feng Xiao, Xu‐Bo Zou, Guang‐Can Guo · Physical Review A · 2007
We present a simple scheme to realize a highly controlled and selective atom-field interaction in cavity quantum electrodynamics system. It is shown that, based on such a selective interaction, nontrivial Dicke states of $N$ trapped neutral atoms can be produced step by step in an optical cavity with a very high fidelity in the presence of the cavity decay. The scheme does not need a single-photon source and its injection into an optical cavity, and the atomic spontaneous emission is strongly suppressed due to a large atom-field detuning.
