Effect of local filtering on Freezing Phenomena of Quantum Correlation

TL;DR

This paper investigates how local filtering operations influence the freezing and dynamical behavior of quantum correlations, revealing that filtering can eliminate freezing phenomena depending on the filtering parameters.

Contribution

It introduces an analysis of the impact of local filtering on quantum correlation dynamics, showing how filtering parameters can control freezing behavior.

Findings

Local filtering can remove freezing in quantum correlations.

Filtering parameters determine the presence or absence of freezing.

The study enhances understanding of quantum correlation control under noise.

Abstract

General quantum correlations measures like quantum discord, one norm geometric quantum discord, exhibit freezing, sudden change, double sudden change behavior in their decay rates under different noisy channels. Therefore, one may attempt to investigate how the freezing behavior and other dynamical features are affected under application of local quantum operations. In this work, we demonstrate the effect of local filtering on the dynamical evolution of quantum correlations. We have found that using local filtering one may remove freezing depending upon the filtering parameter.
