Quantum coherence and quantum correlations are of fundamental and practical significance
for the development of quantum mechanics. They are also cornerstones of quantum …

With the complexity of information tasks, the bipartite and tripartite entanglement can no
longer meet our needs, and we need more entangled particles to process relativistic …

We study the acceleration effect on the genuine tripartite entanglement for one or two
accelerated detector (s) coupled to the vacuum field. Surprisingly, we find that the increase …

We investigated the properties of quantum entanglement and mutual information in the multi-
event horizon Schwarzschild-de Sitter (SdS) spacetime for massless Dirac fields. For the first …

We study Gaussian quantum steering and its asymmetry in the background of a
Schwarzschild black hole. We present a Gaussian channel description of quantum state …

Based on the model of Unruh–Dewitt detector coupled to a massless scalar field, we
investigate the nonlocal advantage of quantum coherence (NAQC) and Bell nonlocality (BN) …

We study the quantum metrology for a pair of entangled Unruh-Dewitt detectors when one of
them is accelerated and coupled to a massless scalar field. Comparing with previous …

In this paper, multipartite entanglement enhancement in an open system under non-inertial
frames via local non-unitary operations is explored. Explicitly, we investigate an available …

A bstract We study the quantum coherence in de Sitter space for the bipartite system of Alice
and Bob who initially share an entangled state between the two modes of a free massive …

In this paper, we analyze the quantum coherence behaviors of a single qubit in the
relativistic regime beyond the single-mode approximation. Firstly, we investigate the freezing …
