Qubit dynamics in a q-deformed oscillators environment

TL;DR

This paper investigates how the quantum coherence and entanglement of one and two qubits evolve over time within a q-deformed oscillators environment, revealing a temperature-dependent slowdown of decoherence in the fermionic case.

Contribution

It introduces a study of qubit dynamics in q-deformed environments, highlighting the temperature-dependent effects on decoherence and entanglement.

Findings

Decoherence slows down in fermionic environments at finite temperature.

Quantum entanglement decay is affected by the nature of the environment.

The environment's deformation parameter influences qubit coherence.

Abstract

We study the dynamics of one and two qubits plunged in a q-deformed oscillators environment. Specifically we evaluate the decay of quantum coherence and entanglement in time when passing from bosonic to fermionic environments. Slowing down of decoherence in the fermionic case is found. The effect only manifests at finite temperature.
