Information extraction and quantum state distortions in continuous variable quantum teleportation

Quantum Physics 2017-08-23 v1

Abstract

We analyze the loss of fidelity in continuous variable teleportation due to non-maximal entanglement. It is shown that the quantum state distortions correspond to the measurement back-action of a field amplitude measurement. Results for coherent states and for photon number states are presented.
