TL;DR
This paper investigates how the quantum Zeno effect can be used to preserve entanglement between two atoms in a lossy resonator, revealing dynamics like revivals and oscillations due to system-reservoir correlations.
Contribution
It introduces a strategy employing the quantum Zeno effect to combat entanglement deterioration in a strongly coupled atom-resonator system.
Findings
Entanglement revivals and oscillations occur in the strong coupling regime.
Quantum Zeno effect can effectively protect entanglement.
Steady-state entanglement behavior analyzed.
Abstract
We study the exact entanglement dynamics of two atoms in a lossy resonator. Besides discussing the steady-state entanglement, we show that in the strong coupling regime the system-reservoir correlations induce entanglement revivals and oscillations and propose a strategy to fight against the deterioration of the entanglement using the quantum Zeno effect.
