Abstract
A generalized teleportation protocol (GTP) for qubits is presented, where the teleportation channels are nonmaximally entangled and all the free parameters of the protocol are considered: Alice’s measurement basis, her sets of acceptable results, and Bob’s unitary operations. The full range of fidelity of the teleported state and the probability of success to obtain a given fidelity are achieved by changing these free parameters. A channel efficiency bound is found, where one can determine how to divide it between and . A one-qubit formulation is presented and then expanded to qubits. A proposed experimental setup that implements the GTP is given using linear optics.
