Optimizing 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....

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 ...

Complete quantum teleportation by nuclear magnetic resonance

Quantum mechanics provides spectacular new information processing abilities . One of the most unexpected is a procedure called quantum teleportation 3 that allows the quantum state of a system to be transported from one location to another, without moving through the intervening space. Partial implementations of teleportation 4,5 over macroscopic distances have been achieved using optical systems,

Quantum teleportation between particlelike and fieldlike qubits using hybrid entanglement under decoherence effects

We study quantum teleportation between two different types of optical qubits, one of which is “particlelike” and the other “fieldlike,” via hybrid entangled states under the effects of decoherence. We find that teleportation from particlelike to fieldlike qubits can be achieved with a higher fidelity than that in the opposite direction. However, teleportation from fieldlike to particlelike qubi...

Characterization of quantum teleportation processes by nonlinear quantum channel and quantum mutual entropy

The quantum mutual entropy was introduced by one of the present authors in 1983 as a quantum extension of the Shannon mutual information. It has been used for several studies such as quantum information transmission in optical communication and quantum irreversible processes. In this paper, a nonlinear channel for a quantum teleportation process is rigorously constructed and the quantum mutual ...
