Yuri Kurochkin, Adarsh S. Prasad, A. I. Lvovsky
TL;DR
This paper reports an experimental demonstration of entanglement distillation for two-mode squeezed states, enhancing their squeezing and entanglement by applying the annihilation operator, which increases the two-photon component.
Contribution
It introduces a novel experimental method for entanglement distillation of two-mode squeezed states using annihilation operators, improving their quantum properties.
Findings
Squeezing and entanglement increased by about 50%
Two-photon component fraction was enhanced
Experimental validation of the distillation process
Abstract
We experimentally demonstrate entanglement distillation of the two mode squeezed state. Applying the annihilation operator to both modes, we increase the fraction of the two-photon component in the state, resulting in the increase of both squeezing and entanglement by about 50%.
