The operational advantages provided by non-classical teleportation

Understand

The standard benchmark for teleportation is the average fidelity of teleportation and according to this benchmark not all states are useful for teleportation.

• It was recently shown however that all entangled states lead to non-classical teleportation, with there being no classical scheme able to reproduce the states teleported to Bob.
• Here we study the operational significance of this result.
• On the one hand we demonstrate that every entangled state is useful for teleportation if a generalization of the average fidelity of teleportation is considered which concerns teleporting quantum correlations.
