Quantum correlations in qutrit-qutrit systems under local quantum noise channels

TL;DR

This paper investigates how various local quantum noise channels affect quantum correlations in qutrit-qutrit systems, using negativity and geometric discord as measures, highlighting the impact of decoherence on high-dimensional quantum information.

Contribution

It provides a detailed analysis of quantum correlation dynamics under different local noise channels in qutrit-qutrit systems, including identical and non-identical decoherence scenarios.

Findings

Quantum correlations decrease under all studied noise channels.

Different noise types have distinct effects on quantum correlations.

Non-identical channels can lead to asymmetric correlation decay.

Abstract

Due to decoherence, realistic quantum systems inevitably interact with the environment when quantum information is processed, which causes the loss of quantum properties. As a fundamental issue of quantum properties, quantum correlations have attracted a lot of interests in recent years. Because of the importance of high dimensional systems in quantum information, in this work, we study the quantum correlations affected by the Markovian environment by considering the quantum correlations of qutrit-qutrit quantum systems measured by the negativity and the geometric discord. The local noise channels covered in this work includes dephasing, trit-flip, trit-phase-flip, and depolarising channels. We have also investigated the cases where the local decoherence channels of two sides are identical and non-identical.
