The distribution of quantum fidelities
Line Hjortshoj Pedersen, Niels Martin Moller, Klaus Molmer
When applied to different input states, an imperfect quantum operation yields output states with varying fidelities, defined as the absolute square of their overlap with the desire…
Dimensional asymptotics of effective actions on S^n, and proof of Bär-Schopka's conjecture
Niels Martin Møller
We study the dimensional asymptotics of the effective actions, or functional determinants, for the Dirac operator D and Laplacians Δ+βR on round S^n. For Laplacians the behavior de…
Fidelity of quantum operations
Line Hjortshoj Pedersen, Klaus Molmer, Niels Martin Moller
We present a derivation and numerous applications of a compact explicit formula for the average fidelity of a quantum operation on a finite dimensional quantum system. The formula…
