Scheme for entangled-mesoscopic-state generation in weakly dissipative cavities
Changyong Chen, Shaohua Li, Mang Feng · Journal of Physics B Atomic Molecular and Optical Physics · 2007
We analytically investigate the generation of mesoscopic entanglement between deformed coherent states which result from the action of the non-standard displacement (displacement-like) operator on the cavity mode vacuum state, and between deformed coherent states and Fock states, based on a dissipative one-photon interaction of a two-level atom with single-mode cavities under strong driving fields. By using the quantum trajectory method and displacement-like operators, we analytically present the detrimental effect of the cavity decay on the generated states and briefly discuss the feasibility of experimental preparation of those states in cavity QED.
