Robustness of deformed catlike states under dissipative decoherence

TL;DR

This paper investigates how deforming harmonic oscillators can produce catlike states with enhanced resistance to decoherence, preserving nonclassical properties and entanglement better than ordinary states under dissipative environments.

Contribution

It demonstrates that deformation parameters can be tuned to create more robust catlike states against decoherence, advancing quantum state preservation techniques.

Findings

Deformed catlike states show increased resistance to decoherence.

Nonclassical properties are better preserved in deformed states.

Entanglement persists longer in deformed catlike states.

Abstract

The generation of coherent superposition of distinct physical systems and the construction of robust entangled states under decoherence are the most experimental challenges of quantum technologies. In this work, we investigate the behaviors of catlike states of a deformed harmonic oscillator under dissipative decoherence. Varying the deformation parameters, we obtain catlike states having more resistance against decoherence than catlike states of the ordinary harmonic oscillator. Furthermore, we study nonclassical properties and entanglement of different catlike states subjects to decoherence caused by a dissipative interaction with a large environment. Depending on different deformation parameters, we reveal that the nonclassical properties of catlike states under dissipative interaction can be more retarded and preserved in the time.
