Quantum teleportation and beam splitting. (Q5961021)

This paper is a sequel to the earlier work by the authors on quantum teleportation with entangled states [Commun. Math. Phys. 222, No. 2, 229--247 (2001; Zbl 0986.81011)]. In this work the models of perfect teleportation and non-perfect teleportation are discussed in a general scheme. For completeness the meaning of teleportation and some basic notions of Fock space are discussed. The notion of perfect teleportation was discussed in a very general scheme and the main theorems for non-perfect teleportation are obtained. The main results of this paper are the differences among the three models viz., the perfect model, the non-perfect model discussed earlier and the one in the present paper.
