INFORMATION TRANSFER IN LEAKY ATOM–CAVITY SYSTEMS
Biplab Ghosh, A. S. Majumdar, N. Nayak · International Journal of Quantum Information · 2006
We consider a system of two enatangled cavities and a single two-level atom passing through one of them. A "monogamy" inequality for this tripartite system is quantitatively studied and verified in the presence of cavity leakage. Next, we consider the simultaneous passage of two-level atoms through both the cavities. Entanglement swapping is observed between the the two-cavity and the two-atom system. Cavity dissipation leads to the quantitative reduction of information transfer though preserving the basic swapping property.
