Conditional Generation Scheme for Entangled Vacuum Evacuated Coherent States by Mixing Two Coherent Beams with a Squeezed Vacuum State

Abstract

Conditions to generate high-purity entangled vacuum-evacuated coherent states ($|0>|\alpha {>}^0-|-\alpha {>}^0|0>$ were studied for two cascade-placed beam splitters, with one squeezed state input and two coherent state inputs whenever a single photon is detected. Controlling the amplitudes and the phases of the beams allows for various amplitudes of the vacuum-evacuated coherent states ($|\alpha {>}^0=|\alpha >-e^{-|\alpha {|}^2}|0>$) up to $\alpha =2.160$ to be manipulated with high-purity.
