Quantum Field Theory in Curved Spacetimes (QFTCS) makes sound predictions in situations involving quantum fields in the presence of strong (classical) gravitational fields. In the last few years, it has been proven extremely fruitful to analyze QFTCS from the perspective of information theory. Thus, in this project, we intend to study the interplay between QFTCS and quantum information theory (QIT) not only to find new low-energy quantum gravity effects (i.e. for energies far below Planck scale) but also to study the influence of relativity in quantum information theory. This will allow us to study entanglement and correlations dynamics as well as the transmission of classical and quantum information in curved spacetimes. It is our hope to be able to shed some light on some open problems such as the destruction of information by black holes and the origin of its entropy. In addition to the interplay between QFTCS and QIT, we also intend to analyze vacuum effects in QFTCS with particular interest in, but not restricted to, spacetimes with bifurcate Killing horizons (such as Minkowski spacetime in the context of the Unruh effect).
