Momentum entanglement and disentanglement between atom and photon
arXiv:quant-ph/0611205 · doi:10.1103/PhysRevA.76.012112
Abstract
With the quantum interference between two transition pathways, we demonstrate a novel 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.
