Quantum Probability and Quantum Information Theory
Hans Maassen
This is an introductory course on quantum probability and quantum information, based on matrix algebras.
A Galton-Watson estimate for Dyson series
Hans Maassen, Dmitri Botvich
We consider the question of convergence of particular series of integrals, which are labeled by rooted trees. Necessary and sufficient criteria for convergence are obtained, togeth…
Continuous Observation of Quantum Systems
Hans Maassen
In a series of papers in the 1980's Alexander Holevo proved a classification theorem for continuous quantum measurement processes, or, as they would today be called, stationary qua…
Matrix forms of immanant inequalities
Felix Huber, Hans Maassen
We translate inequalities and conjectures for immanants and generalized matrix functions into inequalities in the Löwner order. These have the form of trace polynomials and general…
Quasirandom quantum channels
Tom Bannink, Jop Briët, Farrokh Labib +1
Mixing (or quasirandom) properties of the natural transition matrix associated to a graph can be quantified by its distance to the complete graph. Different mixing properties corre…
Optimality of entropic uncertainty relations
Kais Abdelkhalek, René Schwonnek, Hans Maassen +5
The entropic uncertainty relation proven by Maassen and Uffink for arbitrary pairs of two observables is known to be non-optimal. Here, we call an uncertainty relation optimal, if…
