Generation of maximally entangled state from a single-photon state in fiber-connected cavities

Starting from the physical model consisting of two remotely located atoms trapped in high finesse fiber-connected cavities, generation of maximally entangled state is firstly realized theoretically from a initial single-photon state. Result shows that under the regime of strong atom-cavity coupling strength, the averaged fidelity can remarkably exceed 0.9980. The distant creation of maximally entangled state may provides certain opportunities and be helpful in the accomplishment of scalable quantum networks.
