Experimental and Theoretical Aspects of Quantum Teleportation

چکیده
We present a short summary of progress achieved at the Center for Engineering Science Advanced Research (CESAR) of the Oak Ridge National Laboratory (ORNL) in the recently initiated Quantum Teleportation project. The primary objective of this effort is to study the signaling potential of quantum information processing systems based on quantum entanglement. Our initial effort has focused on the development and demonstration of a novel, ultra-bright EPR source, based upon the innovative concept of cascaded type-II optical parametric downconversion. The main features of this source are analyzed, and results of a multi-photon entanglement experiment are presented. Theoretical challenges for superluminal communications are also highlighted.

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 کامل0 Possibility for Teleportation of Nuclei
Since its discovery in 1993, quantum teleportation (QT) is a subject for intense theoretical and experimental efforts. Experimental realizations of QT have so far been limited to teleportation of light. The present letter gives a new experimental scheme for QT of heavy matter. We show that the standard experimental technique used in nuclear physics may be successfully applied to teleportation o...
متن کاملQuantum Teleportation
Given a single copy of an unknown quantum state, it is impossible in principle to identify it. The mostly inaccessible information carried by the state is termed quantum information. In contrast to classical information, it cannot be copied or cloned. This concept provides a theoretical underpinning for all aspects of quantum communication and quantum computation. Here we use it to consider qua...
متن کاملTeleportation of Continuous Quantum Variables: a New Approach
Abstract. Teleportation of optical field states (as continuous quantum variables) is usually described in terms of Wigner functions. This is in marked contrast to the theoretical treatment of teleportation of qubits. In this paper we show that by using the holomorphic representation of the canonical commutation relations, teleportation of continuous quantum variables can be treated in complete ...
