    3. Quantum Teleportation Teleportation: Teleportation means: a person or object disappear while an exact replica appears in the best case immediately at some distant location. Bennett et al. (1993) have suggested that it is possible to transfer the quantum state of a particle onto another particle-the process of quantum teleportation-provided one does not get any information about the state in the course of this transformation. Application: Teleportation can be used in place of wiring in a large quantum computer. To Build a distributed system (e.g. a quantum multicomputer). and so on

    15. Summary Deduced from the basic principles of quantum mechanics, it is possible to transfer the quantum state from one particle onto another over arbitrary distances. As an experimental elaboration of that scheme we discussed the teleportation of polarization states of photons. But quantum teleportation is not restricted to that system at all. One could imagine entangling photons with atoms or photons with ions, and so on. Then teleportation would allow us to transfer the state of, for example, fast decohering, short-lived particles onto some more stable systems. This opens the possibility of quantum memories, where the information of incoming photons could be stored on trapped ions, carefully shielded from the environment. With this application we are in heart of quantum information processing.
