How long can it take for a quantum channel to forget everything?
Andre Ahlbrecht, Florian Richter, Reinhard F. Werner
We investigate quantum channels, which after a finite number of repeated applications erase all input information, i.e., channels whose -th power (but no smaller power) is a…

Asymptotic evolution of quantum walks with random coin
Andre Ahlbrecht, Holger Vogts, Albert H. Werner +1
We study the asymptotic position distribution of general quantum walks on a lattice, including walks with a random coin, which is chosen from step to step by a general Markov chain…
