A modern perspective

Abstract
Quantum Field Theory on Curved Spacetimes is an extension of standard quantum field theory which allows quantum fields to interact with classical gravity, generally taken to be described by general relativity. This is, thus, a paradigm “in-between” standard quantum field theory and full quantum gravity, from which one can learn valuable lessons about the role of general relativistic gravity in quantum physics. Indeed, it has already had enormous success in the description of the quantum evaporation of black holes a la Hawking, and of the early universe where cosmological perturbations are now universally described by quantum fields.
The goal of this short course is to provide a pedagogical introduction to this theoretical framework and some of its main predictions. The presentation will differ from traditional approaches in that it will rest on techniques from Gaussian quantum information. This novel perspective brings to the forefront genuine quantum aspects that are more difficult to describe using traditional tools, such as the generation of quantum entanglement in the process of black hole evaporation and the early universe.
The course will be largely self-contained. Familiarity with quantum mechanics, at the level of the book by Sakurai, will be assumed. But previous knowledge of quantum field theory and general relativity, although helpful, will not be essential.
