摘要：
We study entanglement swapping and quantum communication in the context of cavity QED. We first present an entanglement swapping scheme in cavities where two atoms without interacting previously can be entangled with the success probability unity. Then, conditioned on a novel property of entanglement swapping, we propose a secure direct communication protocol, in which two legitimate users can communicate deterministically.
