Light cones for open quantum systems
Sébastien Breteaux, Jérémy Faupin, Marius Lemm +3
We consider Markovian open quantum dynamics (MOQD). We show that, up to small-probability tails, the supports of quantum states evolving under such dynamics propagate with finite s…

Maximal Speed of Propagation in Open Quantum Systems
Sébastien Breteaux, Jérémy Faupin, Marius Lemm +1
We prove a maximal velocity bound for the dynamics of Markovian open quantum systems. The dynamics are described by one-parameter semi-groups of quantum channels satisfying the von…
