Concerted efforts are underway to establish an infrastructure for a global quantum Internet to
realise a spectrum of quantum technologies. This will enable more precise sensors, secure …

The study of entanglement in particle physics has been gathering pace in the past few years.
It is a new field that is providing important results about the possibility of detecting …

The traditional view from particle physics is that quantum-gravity effects should become
detectable only at extremely high energies and small length scales. Owing to the significant …

We perform a detailed analysis of the possible violation of various Bell-type inequalities for
systems of vector boson-antiboson pairs. Considering the general case of an overall scalar …

We present an overview of the quantitative theory of single-copy entanglement in finite-
dimensional quantum systems. In particular we emphasize the point of view that different …

Advances in quantum technologies are giving rise to a revolution in the way fundamental
physics questions are explored at the empirical level. At the same time, they are the seeds …

The solutions of many issues, of the ongoing efforts to make deformed graphene a tabletop
quantum field theory in curved spacetimes, are presented. A detailed explanation of the …

We investigate the consequences of space-time being curved on space-based quantum
communication protocols. We analyze tasks that require either the exchange of single …

We apply genuine multipartite entanglement concurrence to investigate entanglement
properties of Dirac fields in noninertial frames. We present analytical concurrences for …

Abstract We review Unruh–DeWitt detectors and other models of detector–field interaction in
a relativistic quantum field theory setting as a tool for extracting detector–detector, field–field …
