Quantum Teleportation

چکیده
Teleportation the transmission and reconstruction of objects over arbitrary distances is a spectacular process, which actually has been invented by science fiction authors some decades ago. Unbelievable as it seems in 1993 a theoretical scheme has been found by Charles Bennett et al. that predicts the existence of teleportation in reality at least for quantum systems. This scheme exploits some of the most essential and most fascinating features of quantum theory, such as the existence of entangled quantum states. Only four years after its prediction, for the first time quantum teleportation has been experimentally realized by Anton Zeilinger et al., who succeeded in teleporting the polarization state of photons. Apart from the fascination that arises from the possibility of teleporting particles, quantum teleportation is expected to play a crucial role in the construction of quantum computers in future.

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....
متن کاملTeleportation 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 ...
متن کاملDisentangling Nonlocality and Teleportation
Quantum entanglement can be used to demonstrate nonlocality and to teleport a quantum state from one place to another. The fact that entanglement can be used to do both these things has led people to believe that teleportation is a nonlocal effect. In this paper it is shown that teleportation is conceptually independent of nonlocality. This is done by constructing a toy local theory in which cl...
متن کاملQuantum Teleportation : from Pure to Mixed States and Standard to Optimal
Teleportation for pure states, mixed states with standard and optimal protocols are introduced and investigated systematically. An explicit equation governing the teleportation of finite dimensional quantum pure states by a generally given non-local entangled state is presented. For the teleportation of a mixed state with an arbitrary mixed state resource, an explicit expression is obtained for...
متن کامل“TelePOVM” – More Faces of Teleportation
We show two new aspects of teleportation based on generalized measurements: I. We present an alternative approach to teleportation based on “generating ρ-ensembles at spacetime separation”; This approach provides a better understanding of teleportation. II. We define the concept of conclusive teleportation and we show how to teleport a quantum state using any pure entangled state; we show how t...
متن کاملQuantum teleportation of composite systems via mixed entangled states
We analyze quantum teleportation for composite systems, specifically for concatenated teleporation decomposing a large composite state into smaller states of dimension commensurate with the channel and partial teleportation teleporting one component of a larger quantum state . We obtain an exact expression for teleportation fidelity that depends solely on the dimension and singlet fraction for ...
