q-deformed noncommutative cat states and their nonclassical properties

TL;DR

This paper investigates q-deformed noncommutative cat states, revealing their unique nonclassical properties, enhanced squeezing capabilities, and potential advantages over standard quantum states in noncommutative space.

Contribution

It introduces q-deformed noncommutative cat states, demonstrating their nonclassical features and showing how the q-deformation parameter enables simultaneous quadrature and number squeezing.

Findings

Q-deformed coherent states are minimum uncertainty states with squeezed photon distributions.

Q-deformed cat states exhibit enhanced squeezing properties compared to ordinary states.

The q-deformation parameter allows achieving both quadrature and number squeezing simultaneously.

Abstract

We study several classical like properties of q-deformed nonlinear coherent states as well as nonclassical behaviours of q-deformed version of the Schrodinger cat states in noncommutative space. Coherent states in q-deformed space are found to be minimum uncertainty states together with the squeezed photon distributions unlike the ordinary systems, where the photon distributions are always Poissonian. Several advantages of utilising cat states in noncommutative space over the standard quantum mechanical spaces have been reported here. For instance, the q-deformed parameter has been utilised to improve the squeezing of the quadrature beyond the ordinary case. Most importantly, the parameter provides an extra degree of freedom by which we achieve both quadrature squeezed and number squeezed cat states at the same time in a single system, which is impossible to achieve from ordinary cat states.
