Generalized teleportation protocol
Goren Gordon, Gustavo Rigolin · Physical Review A · 2006
A generalized teleportation protocol (GTP) for $N$ 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 $(F)$ of the teleported state and the probability of success $({P}_{\mathit{suc}})$ 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 $F$ and ${P}_{\mathit{suc}}$. A one-qubit formulation is presented and then expanded to $N$ qubits. A proposed experimental setup that implements the GTP is given using linear optics.
