TL;DR
This paper investigates how non-Markovian environments induce quantum interference effects that lead to quantum beats in entanglement and discord, and explores methods to preserve quantum correlations.
Contribution
It reveals the role of structured reservoirs in generating quantum beats and proposes strategies for preserving quantum correlations through suppression of spontaneous emission.
Findings
Quantum beats in entanglement and discord due to non-Markovian effects
Quantum interference between correlation oscillations observed
Quantum correlations can be preserved by suppressing spontaneous emission
Abstract
For two qubits independently coupled to their respective structured reservoirs (Lorentzian spectrum), quantum beats for entanglement and discord are found which are the result of quantum interference between correlation oscillations induced by local non-Markovian environments. We also discuss the preservation of quantum correlations by the effective suppression of the spontaneous emission.
