Purification of quantum trajectories
Hans Maassen, Burkhard Kümmerer
We prove that the quantum trajectory of repeated perfect measurement on a finite quantum system either asymptotically purifies, or hits upon a family of `dark' subspaces, where the…
Quantum probability applied to the damped harmonic oscillator
Hans Maassen
In this introductory course we sketch the framework of quantum probability in order to discuss open quantum systems, in particular the damped harmonic oscillator.
The Quantum Monty Hall Problem
G. M. D'Ariano, R. D. Gill, M. Keyl +3
We consider a quantum version of a well-known statistical decision problem, whose solution is, at first sight, counter-intuitive to many. In the quantum version a continuum of poss…
An Ergodic Theorem for Quantum Counting Processes
Burkhard Kuemmerer, Hans Maassen
For a quantum-mechanical counting process we show ergodicity, under the condition that the underlying open quantum system approaches equilibrium in the time mean. This implies equa…
