Quantum Teleportation: Difference between revisions

This [https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.70.1895 example protocol] performs the task of quantum teleportation by which a quantum state (or information stored in a quantum state) can be transmitted physically from one location (or one party) to another. This protocol requires sharing an [[entangled state]] like an [[EPR pair]] between two parties and also allowing the parties to communicate classically (sending bits of information). Quantum Teleportation can be treated as a send/receive scheme for qubits. Quantum teleportation provides a mechanism of sending an unknown qubit from one location to another, without physically moving the particle. This task can be done due to the existence of long-range correlations between entangled pairs. The quantum teleportation is used widely as a basic protocol in many other quantum communication and quantum cryptography protocols.
