Probabilistic teleportation of two - particle entangled state

In this report, two different probabilistic teleportations of a two-particle entangled state by pure entangled three-particle state are shown. Their successful probabilities are different. 03.65.Bz, 03.67.-a Typeset using REVTEX ∗E-mail: [email protected] †E-Mail: [email protected] 1 Quantum teleportation, proposed by Bennett et.al [1], is the process that transmits an unknown two-state particl...

Teleportation of a two - particle entangled state via W class states

A scheme for teleporting an unknown two-particle entangled state via W class states is proposed. In this scheme, the W class entangled states are considered as quantum channels. It is shown that by means of optimal discrimination between two nonorthogonal quantum states, probabilistic teleportation of the two-particle entangled state can be achieved. PACS: 03.67.Hk; 03.65.Bz

Quantum probabilistic teleportation via entangled coherent states

We study the entanglement of entangled coherent states in vacuum environment by employing the entanglement of formation and propose a scheme to probabilistically teleport a coherent superposition state via entangled coherent states, in which the amount of classical information sent by Alice is restricted to one bit. The influence of decoherence due to photon absorpation is considered. It is sho...

Teleportation via an Entangled Coherent Channel and Decoherence Effect on This Channel

We study an entangled two-mode coherent state within the framework of2×2-dimensional Hilbert space. We investigate the problem of quantum teleportation ofa superposition coherent state via an entangled coherent channel. By three differentmeasures with the titles ``minimum assured fidelity (MASF)”, ``average teleportationfidelity” and ``optimal fidelity (f)” we study the ...
