Optimal schemes for quantum teleportation of N-particle generalized Bell-type states

Abstract

An optimal scheme is presented for the quantum teleportation of an arbitrary [Formula: see text]-particle generalized Bell-type state. In this paper, we have discussed three examples of two-particle, three-particle, and four-particle generalized Bell-type state in detail. Not only that, we have also analyzed the specific optimization process of quantum teleportation. Compared with previous schemes, our scheme has less quantum cost and transmission complexity due to the optimized quantum channel and operations.
