Central limit theorem for reducible and irreducible open quantum walks
Przemysław Sadowski, Łukasz Pawela · Quantum Information Processing · 2016
In this work we aim at proving central limit theorems for open quantum walks on $${\mathbb {Z}}^d$$ . We study the case when there are various classes of vertices in the network. In particular, we investigate two ways of distributing the vertex classes in the network. First, we assign the classes in a regular pattern. Secondly, we assign each vertex a random class with a transition invariant distribution. For each way of distributing vertex classes, we obtain an appropriate central limit theorem, illustrated by numerical examples. These theorems may have application in the study of complex systems in quantum biology and dissipative quantum computation.
