Statistical Mechanics of Repeated Quantum Measurements

Vojkan Jaksic (Department of Mathematics and Statistics, McGill University, Canada)


The statistics of the (finite alphabet) outcomes of repeated quantum
measurements is studied by methods of thermodynamic formalism. Viewed
as one-dimensional spin systems with long range interactions, repeated quantum
measurements exhibit very rich (and sometimes very singular) thermodynamic
behaviour. We will describe general thermodynamical formalism of these systems
and illustrate its unexpected features on a number of examples.

This talk is based on joint works with T. Benoist, N. Cuneo, Y. Pautrat, and C-A. Pillet.
