Momentum entanglement and disentanglement between an atom and a photon
Rui Guo, Hong Mei Guo · Physical Review A · 2007
With the quantum interference between two transition pathways, we demonstrate a scheme to coherently control the momentum entanglement between a single atom and a single photon. The unavoidable disentanglement is also studied from the first principle, which indicates that the stably entangled atom-photon system with superhigh degree of entanglement may be realized with this scheme under certain conditions.
