Optimal teleportation based on bell measurements

Sergio Albeverio, Shao-Ming Fei, Wen‐Li Yang

Abstract

We study optimal teleportation based on Bell measurements. An explicit expression for the quantum channel associated with the optimal teleportation with an arbitrary mixed state resource is presented. The optimal transmission fidelity of the corresponding quantum channel is calculated and shown to be related to the fully entangled fraction of the quantum resource, rather than the singlet fraction as in the standard teleportation protocol.
