We revisit the entanglement harvesting protocol when two detectors are in causal contact.
We study the role of field-mediated communication in generating entanglement between the …

We present a new operational framework for studying “superpositions of spacetimes,” which
are of fundamental interest in the development of a theory of quantum gravity. Our approach …

We study the protocol of entanglement harvesting when the particle detectors that harvest
entanglement from the field are replaced by fully relativistic quantum field theories. We show …

Within any anticipated unifying theory of quantum gravity, it should be meaningful to
combine the fundamental notions of quantum superposition and spacetime to obtain so …

We study how quantum systems can harvest entanglement from the quantum degrees of
freedom of the gravitational field. Concretely, we describe in detail the interaction of …

It is a well-known fact that, in recent times, entanglement harvesting from the quantum field is
being rigorously investigated further in flat and different curved backgrounds. The usually …

A bstract We study the dynamics of an Unruh-DeWitt detector interacting with a massless
scalar field in an arbitrary static spherically symmetric spacetimes whose metric is …

We analyze the differences between relativistic fields with or without quantum degrees of
freedom in relativistic quantum information protocols. We classify the regimes where the …

We present a fully relativistic model for localized probes in quantum field theory.
Furthermore, we show that it is possible to obtain particle detector models from localized …

We reveal that the information exchange between particle detectors and their ability to
harvest correlations from a quantum field can interfere constructively and destructively. This …
