Protecting, Enhancing and Reviving Entanglement

TL;DR

This paper introduces strategies using Zeno-like measurements to protect, enhance, and revive entanglement in a double Jaynes-Cummings model, revealing surprising dynamical features.

Contribution

It presents a novel approach employing Zeno-like measurements to control entanglement dynamics in quantum systems.

Findings

Zeno-like measurements can protect entanglement.

Measurements can revive entanglement after decay.

Enhanced entanglement dynamics observed in the model.

Abstract

We propose a strategies not only to protect but also to enhance and revive the entanglement in a double Jaynes-Cummings model. We show that such surprising features arises when Zeno-like measurements are performed during the dynamical process.
