The evolution of expanding spacetime realizes approximate quantum cloning
Laura Niermann, Tobias J. Osborne
We investigate how quantum information, encoded in a quantum field, evolves during the expansion of spacetime. Due to information loss across the horizon, a local observer experien…
Particle detectors in superposition in de Sitter spacetime
Laura Niermann, Luis C. Barbado
Cosmological particle creation is the phenomenon by which the expansion of spacetime results in the production of particles of a given quantum field in that spacetime. In this pape…
Holographic networks for (1+1)-dimensional de Sitter spacetime
Laura Niermann, Tobias J. Osborne
Holographic tensor networks associated to tilings of (1+1)-dimensional de Sitter spacetime are introduced. Basic features of these networks are discussed, compared, and contrasted…
From categories to anyons: a travelogue
Kerstin Beer, Dmytro Bondarenko, Alexander Hahn +8
In this paper we provide an overview of category theory, focussing on applications in physics. The route we follow is motivated by the final goal of understanding anyons and topolo…
