We revisit the problem of the thermalization process in an entropic formulation for the Unruh-
DeWitt (UDW) detector outside a Schwarzschild black hole. We derive the late-time …

Quantum metrology studies the ultimate precision limit of physical quantities by using
quantum strategy. In this paper we apply the quantum metrology technologies to the …

A bstract Relativistic quantum metrology studies the maximal achievable precision for
estimating a physical quantity when both quantum and relativistic effects are taken into …

A bstract Relativistic quantum metrology is the study of optimal measurement procedures
within systems that have both quantum and relativistic components. Here we use Unruh …

We revisit the problem of thermalization process for an Unruh-DeWitt (UDW) detector in de
Sitter space. We derive the full dynamics of the detector in the context of open quantum …

In this paper, our prime objective is to apply the techniques of parameter estimation theory
and the concept of Quantum Metrology in the form of Fisher Information to investigate the …

In this paper, we investigate the quantum coherence extraction for two accelerating Unruh-
DeWitt detectors coupling to a scalar background in $3+ 1$ Minkowski spacetime. We find …

We investigate the equilibrium and nonequilibrium quantum information correlations
encoded in a two-qubit system in curved spacetime near the horizon of a Kerr black hole …

In this work, we investigate how the anisotropy affects the cosmological parameters
estimation. Here the anisotropy is incorporated as a small gravitational disturbance. We …

In the past decade, relativistic quantum information (RQI) has presented itself as a promising
avenue for examining the interaction between relativistic and quantum effects. This is most …
