<b>Nonequilibrium phase transitions in open (1+1)D quantum cellular automata</b><br /><br />

Recent advances in quantum technology have paved the way towards synthetic quantum systems. These allow the controlled assembly of many-body systems and the exploration of the impact of quantum fluctuations on non-equilibrium processes. One framework in which such investigation can take place is that of quantum generalized probabilistic cellular automata. These are implemented in two-dimensional qubit lattice systems, where a one-dimensional quantum state is propagated along a fictitious discrete time dimension via the sequential application of quantum gates. I will show how this setting - which is closely related to quantum neural networks - allows to incorporate quantum and classical processes and how it enables the exploration of emergent universal behavior near non-equilibrium phase transitions. I will also discuss briefly ideas concerning the utilization of non-equilibrium quantum many-body systems for quantum information storage and metrology.<br /><br />
