Topological lower bound on quantum chaos by entanglement growth
Zongping Gong, Lorenzo Piroli, J. Ignacio Cirac
A fundamental result in modern quantum chaos theory is the Maldacena-Shenker-Stanford upper bound on the growth of out-of-time-order correlators, whose infinite-temperature limit i…
Quantum Cellular Automata, Tensor Networks, and Area Laws
Lorenzo Piroli, J. Ignacio Cirac
Quantum Cellular Automata are unitary maps that preserve locality and respect causality. We identify them, in any dimension, with simple tensor networks (PEPU) whose bond dimension…
Quantum chaos in the Brownian SYK model with large finite : OTOCs and tripartite information
Christoph Sünderhauf, Lorenzo Piroli, Xiao-Liang Qi +2
We consider the Brownian SYK model of interacting Majorana fermions, with random couplings that are taken to vary independently at each time. We study the out-of-time-ordered c…
