Dressed infrared quantum information
Daniel Carney, Laurent Chaurette, Dominik Neuenfeld +1
We study information-theoretic aspects of the infrared sector of quantum electrodynamics, using the dressed-state approach pioneered by Chung, Kibble, Faddeev-Kulish and others. In…
Infrared quantum information
Daniel Carney, Laurent Chaurette, Dominik Neuenfeld +1
We discuss information-theoretic properties of low-energy photons and gravitons in the S-matrix. Given an incoming n-particle momentum eigenstate, we demonstrate that unobserved so…
Scattering with partial information
Daniel Carney, Laurent Chaurette, Gordon Semenoff
We study relativistic scattering when one only has access to a subset of the particles, using the language of quantum measurement theory. We give an exact, non-perturbative formula…
