A converse to Lieb-Robinson bounds in one dimension using index theory
Daniel Ranard, Michael Walter, Freek Witteveen
Unitary dynamics with a strict causal cone (or "light cone") have been studied extensively, under the name of quantum cellular automata (QCAs). In particular, QCAs in one dimension…
Fluctuations of subsystem entropies at late times
Jordan Cotler, Nicholas Hunter-Jones, Daniel Ranard
We study the fluctuations of subsystem entropies in closed quantum many-body systems after thermalization. Using a combination of analytics and numerics for both random quantum cir…
Emergent classicality in general multipartite states and channels
Xiao-Liang Qi, Daniel Ranard
In a quantum measurement process, classical information about the measured system spreads throughout the environment. Meanwhile, quantum information about the system becomes inacce…
