Open quantum walks: A mini review of the field and recent developments

I Sinayskiy, F Petruccione - The European Physical Journal Special Topics, 2019 - Springer
Open quantum walks (OQWs) are a class of quantum walks, which are purely driven by the
interaction with the dissipative environment. In this paper, we review theoretical advances …
