Abstract
We propose protocols for the entanglement swapping of distant atomic Bose-Einstein condensates using the photon entanglement states as the quantum channel. Two protocols are introduced: one is a single-photon scheme in which an entangled single-photon state serves as the quantum channel, and the other is a multi-photon scheme where an entangled coherent state of the probe lasers is used as the quantum channel.
