Quantum information in curved spacetime - NTMF095
|
|
|
||
In this course, we shall study some fascinating phenomena that arise when the fields of general relativity,
quantum
field theory, and quantum information are put together. In particular, we shall discuss how to locally measure
quantum fields in curved spacetime by using particle Unruh-de Witt (UdW) detectors, and show how such
detectors can be used to uncover global spacetime features. We shall also review the Unruh effect, study
entanglement harvesting, discuss quantum energy teleportation, and more. Basic knowledge of general relativity
and quantum theory is required.
