[HTML][HTML] Quantum Fisher information as a probe for Unruh thermality
J Feng, JJ Zhang - Physics Letters B, 2022 - Elsevier
A long-standing debate on Unruh effect is about its obscure thermal nature. In this Letter, we
use quantum Fisher information (QFI) as an effective probe to explore the thermal nature of …

Tetrapartite entanglement features of W-Class state in uniform acceleration
Using the single-mode approximation, we first calculate entanglement measures such as
negativity (1–3 and 1–1 tangles) and von Neumann entropy for a tetrapartite W-Class …
