quote:A generalized teleportation protocol (GTP) for N qubits is presented, where the teleportation channels are non-maximally 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_{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_{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.
Is this an important article? How far does the physics establishment (if such exists) think this can go?

This is just taking teleportation to the next level of experimentation. Teleportation of one quantum bit (qubit) has been achieved. The next step is to transmit more than one qubit without losing information. Without delving into the derived formulas, it appears that the proposed GTP is trying to create rules by which errors can be found and eliminated (thereby circumventing the Heisenberg Uncertainty Principle). In other words, they are developing standards for the creation of the Heisenberg compensator of Star Trek lore.
