We propose a projective operator formalism that is well-suited to study the correlations of quantum fields in non-inertial frames and curved spacetimes. We generalize a Glauber model of detection of a single localized field mode to allow for making measurements in an arbitrary reference frame. We show that the model correctly reproduces the Unruh temperature formula of a single accelerated detector, and use it to extract vacuum entanglement by a pair of counter-accelerating detectors.

Continuous variable methods in relativistic quantum information: characterization of quantum and classical correlations of scalar field modes in noninertial frames
We review a recently introduced unified approach to the analytical quantification of correlations in Gaussian states of bosonic scalar fields by means of Renyi-2 entropy. This allows us to obtain
Discriminating quantum field theories in non-inertial frames
Quantum channel discrimination is used to test quantum field theory in non-inertial frames. We search for the optimal strategies which can best see the thermality of the Unruh effect. We find that

Relativistic Quantum Metrology in Open System Dynamics
TLDR
This work investigates the evolution of a two-level atom as a detector which interacts with a massless scalar field using the master equation approach for open quantum system and finds the optimal precision of estimation is achieved when the detector evolves for a long enough time.

The quantum and classical correlations are quantified by means of the coherent and mutual information, respectively, where we use the single-mode approximation. It is shown that the users can
The fate of non-trivial entanglement under a gravitational collapse
We analyse the evolution of the entanglement of a non-trivial initial quantum field state (which, for simplicity, has been taken to be a bipartite state made out of vacuum and the first excited
Two-mode Gaussian quantum states measured by collinearly and noncollinearly accelerating observers
We generalize $1+1$-dimensional formalism derived by Ahmadi et. al. [Phys. Rev. D \textbf{93}, 124031] to investigate an effect of relativistic acceleration on localized two-mode Gaussian quantum

Entangling moving cavities in noninertial frames.
TLDR
A scheme for storing quantum information in the field modes of cavities moving in flat space-time is proposed and it is found that in principle it is always possible to produce maximally entangled states between the cavities.
Alice falls into a black hole: entanglement in noninertial frames.
TLDR
It is shown that a state which is maximally entangled in an inertial frame becomes less entangled if the observers are relatively accelerated, which shows that entanglement is an observer-dependent quantity in noninertial frames.
