Correlation dynamics of a two-qubit system in a Bell-diagonal state under non-identical local noises

TL;DR

This paper investigates how quantum and classical correlations in a two-qubit system evolve under non-identical local noise channels, considering both Markovian and non-Markovian environments, revealing decay patterns based on noise types and parameters.

Contribution

It extends previous studies by analyzing the dynamics of correlations with non-identical local noise channels in both Markovian and non-Markovian regimes.

Findings

Decay rules depend on noise types and parameters

Quantum and classical correlations exhibit distinct decay behaviors

Non-identical noise channels influence correlation dynamics differently

Abstract

The property of quantum correlation has been studied in recent years, especially for the quantum and classical correlations affected by environment. The dynamics of quantum and classical correlations in two-qubit system under identical local noise channels have been investigated recently. Here we will consider the dynamics of quantum and classical correlations when the local noise channels of two sides are not identical. We investigate the dynamics of quantum and classical correlations with three types of local noise channels in both Markovian and non-Markovian conditions, and show the decay rules of quantum and classical correlations with different types and parameter times of local noise channels.
