Transforming squeezed light into a large amplitude coherent state superposition
arXiv:0708.1956 · doi:10.1103/PhysRevA.76.043840
Abstract
A quantum superposition of two coherent states of light with small amplitude can be obtained by subtracting a photon from a squeezed vacuum state. In experiments this preparation can be made conditioned on the detection of a photon in the field from a squeezed light source. We propose and analyze an extended measurement strategy which allows generation of high fidelity coherent state superpositions with larger amplitude.
