Optical amplifier-powered quantum optical amplification
arXiv:1105.3132 · doi:10.1103/PhysRevA.83.053818
Abstract
I show that an optical amplifier, when combined with photon subtraction, can be used for quantum state amplification, adding noise at a level below the standard minimum. The device could be used to significantly decrease the probability of incorrectly identifying coherent states chosen from a finite set.
