摘要：

We study entanglement swapping through nonmaximally entangled states. The combination of the standard protocol with an optimal scheme for quantum state discrimination leads to a reliable protocol for the conclusive probabilistic generation of maximally entangled states. A possible setup based on cold trapped ions is proposed.
