Fundamental quantum limits for practical devices

Quantum Physics 2011-04-25 v1

Abstract

We present experimentally testable quantum limitations on the phase-insensitive linear amplification and phase conjugation with respect to the transformation of a Gaussian distributed set of coherent states following the footing to assess the success of continuous-variable quantum teleportation and quantum memory devices. The results enable us to compare the real device with the quantum limited device via feasible input of coherent states.
