Quantum Teleportation and Beam Splitting

چکیده
Following the previous paper in which quantum teleportation is rigorously discussed with coherent entangled states given by beam splittings, we further discuss two types of models, perfect teleportation model and non-perfect teleportation model, in general scheme. Then the difference among several models, i.e., the perfect models and the non-perfect models, is studied. Our teleportation models are constructed by means of coherent states in some Fock space with counting measures, so that our model can be treated in the frame of usual optical communication.

Quantum Teleportation with Entangled States given by Beam Splittings
Quantum teleportation is rigorously discussed with coherent entangled states given by beam splittings. The mathematical scheme of beam splitting has been used to study quantum communication [2] and quantum stochastic [8]. We discuss the teleportation process by means of coherent states in this scheme for the following two cases: (1) Delete the vacuum part from coherent states, whose compensatio...
متن کاملOptimizing Teleportation Cost in Multi-Partition Distributed Quantum Circuits
There are many obstacles in quantum circuits implementation with large scales, so distributed quantum systems are appropriate solution for these quantum circuits. Therefore, reducing the number of quantum teleportation leads to improve the cost of implementing a quantum circuit. The minimum number of teleportations can be considered as a measure of the efficiency of distributed quantum systems....

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 ...
متن کاملA Generalization of Quantum Teleportation and Splitting of Entanglement via Local Cloning
In the original one-to-one teleportation protocol of Bennett et al. [1], an observer Alice transmits the information of a d-level system to another observer Bob with perfect ˇdelity, by using a maximally entangled state. We introduce a generalization called the many-to-many teleportation, where the information is sent from N observers to M receivers situated at different locations. One of the m...
متن کاملQuantum teleportation of entangled coherent states
We propose a simple scheme for the quantum teleportation of both bipartite and multipartite entangled coherent states with the success probability 1/2. The scheme is based only on linear optical devices such as beam splitters and phase shifters, and two-mode photon number measurements. The quantum channels described by the multipartite maximally entangled coherent states, are readily made by th...
