Single-atom as a macroscopic entanglement source
We discuss the generation of a macroscopic entangled state in a single atom cavity-QED system. The three-level atom in a cascade configuration interacts dispersively with two classical coherent fields inside a doubly resonant cavity. We show that a macroscopic entangled state between these two cavity modes can be generated under large detuning conditions. The entanglement persists even under the presence of cavity losses
Generating an entangled coherent state of two cavity modes in a three-level \Lambda - type atomic system
In this paper, we present a scheme to generate an entangled coherent state by
considering a three-level \Lambda - type atom interacting with a two-mode
cavity driven by classical fields. The two-mode entangled coherent state can be
obtained under large detuning conditions. Considering the cavity decay, an
analytical solution is deduced.Comment: 3 figure
