Children: Ellen (1987), Bas (1989), Toon (1991), Pieter and Inge (1994).
As an associate professor in
Mathematical Physics at the
Mathematics department
of the
Radboud University Nijmegen
I do research on
quantum probability
or non-commutative probability,
a generalisation of probability theory that is broad enough to
contain quantum mechanics.
This work is part of the Geometry and Quantum Theory
(GQT)
research cluster of connected universities in the Netherlands.
In collaboration with
Burkhard Kümmerer
we are developing the theory of quantum Markov chains,
their asymptotic completeness and ergodic theory,
with applications to quantum optics.
Our focal point is shifting towards quantum information and control theory,
an area which is rapidly becoming relevant to experimental physicists.
My former Ph.D. student
Luc Bouten
now works on this subject at the California Institute of Technology.
My former collaborator
Madalin Guta
works on quantum statistics.
I teach probability, linear programming,
stochastic processes and stochastic analysis, and mathematical modeling.
Special topics: quantum information and quantum computing,
constructive quantum field theory.
