Teleportation is defined in quantum information and computation as the process by which a (multi)qubit state is transferred from one location to another. It involves EPR or long range quantum entanglement but to differ it from the science fiction version of teleportation, it requires a classical communication channel. Here the basic ideas of quantum teleportation will be described using a standard circuit model of quantum computation, unitary operations and a measuring procedure. Closely related dense coding and non-cloning theorem will be explained. Also some experiments will be described and importance of teleportation for quantum information exchange will be stressed.
