Vacuum - induced stationary entanglement in radiatively coupled three - level atoms

TL;DR

This paper investigates how spontaneous emission in closely spaced three-level atoms coupled to a common vacuum can produce stable entanglement in their long-term states, highlighting the role of collective damping.

Contribution

It demonstrates that collective damping in radiatively coupled three-level atoms can generate robust stationary entanglement due to spontaneous emission.

Findings

Collective damping leads to entanglement in asymptotic states.

Close atomic separation enhances entanglement stability.

Spontaneous emission can be a resource for entanglement generation.

Abstract

We consider a pair of three - level atoms interacting with a common vacuum and analyze the process of entanglement production due to spontaneous emission. We show that in the case of closely separated atoms, collective damping can generate robust entanglement of the asymptotic states.
