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

At the beginning of the previous century, Newtonian mechanics was advanced by two new
revolutionary theories, Quantum Mechanics (QM) and General Relativity (GR). Both theories …

We show that two quantities in quantum metrology that were thought to be the same, the
quantum Fisher information matrix and the Bures metric, are not the same. They differ at …

We study the dynamics of quantum coherence under Unruh thermal noise and seek under
which condition the coherence can be frozen in a relativistic setting. We find that the frozen …

We study the separability in multiqubit pure and mixed Greenberger-Horne-Zeilinger (GHZ)
and W states with an accelerating qubit using the Abe-Rajagopal (AR) q-conditional entropy …

An object moving with the acceleration will change the temperature of environment around
it, because of the presence of the Unruh thermal effect. In this work, we investigate the …

We investigate the ultimate estimation precision, characterized by the quantum Fisher
information, of a two-level atom as a detector which is coupled to massless scalar field in the …

We address the issue of precisely estimating small parameters encoded in a general linear
transformation of the modes of a bosonic quantum field. Such Bogoliubov transformations …

It is found that the Unruh effect can not only arise out of the entanglement between two sets
of modes spanning the left and right Rindler wedges, but also between modes spanning the …

Considering a pair of Unruh–DeWitt detectors, when one of them is kept inertial and the
other one is accelerated and coupled to a scalar field, we address the teleportation of a two …
