Hawking effect can generate physically inaccessible genuine tripartite nonlocality

TL;DR

This paper investigates how Hawking radiation affects genuine tripartite nonlocality, revealing it can both degrade and generate nonlocality, with implications for black hole physics and quantum information.

Contribution

It is the first to show Hawking effect can create physically inaccessible GTN and derive analytical tradeoff relations for GTE and coherence under Hawking influence.

Findings

Hawking radiation causes sudden death of accessible GTN.

Hawking effect can generate inaccessible GTN for fermions.

Analytical tradeoff relations for GTE and coherence were derived.

Abstract

We explore the acceleration effect on the genuine tripartite nonlocality (GTN) for one or two accelerated detector(s) coupled to the vacuum field with initial mixed tripartite states. We show that the Hawking radiation degrades the physically accessible GTN, which suffers from "sudden death" at certain critical Hawking temperature. An novel phenomenon has been observed first time that the Hawking effect can generate the physically inaccessible GTN for fermion fields in curved spacetime, the "sudden birth" of the physically inaccessible GTN. This result shows that the GTN can pass through the event horizon of black hole for certain mixed initial states. We also derived analytically the tradeoff relations of genuine tripartite entanglement (GTE) and quantum coherence under the influence of Hawking effect.
