Extraction of a squeezed state in a field mode via repeated measurements on an auxiliary quantum particle

TL;DR

This paper demonstrates that repeated measurements on an auxiliary particle can effectively generate a squeezed state in a field mode, regardless of the initial state, by analyzing the system's dynamics and parameter dependencies.

Contribution

It introduces a method to produce squeezed states in a field mode through repeated measurements on an interacting particle, highlighting a novel measurement-based state engineering technique.

Findings

The field mode is distilled into a squeezed state regardless of initial conditions.

The dynamics depend on specific physical parameters of the system.

Repeated measurements effectively induce squeezing in the field mode.

Abstract

The dynamics of a system, consisting of a particle initially in a Gaussian state interacting with a field mode, under the action of repeated measurements performed on the particle, is examined. It is shown that regardless of its initial state the field is distilled into a squeezed state. The dependence on the physical parameters of the dynamics is investigated.
