Entanglement and disentanglement between single atom and photon in the momentum space
Rui Guo, Hong Chen Guo · arXiv (Cornell University) · 2006
With the quantum interference between two transition pathways, we demonstrate a novel scheme to coherently control the momentum entanglement between a single atom and photon. The unavoidable disentanglement is also studied from the first principle, which indicates that the stably entangled system with superhigh degree of entanglement may be realized with this scheme under certain conditions.
