# Quantum Entanglement Growth Under Random Unitary Dynamics

@article{Nahum2016QuantumEG, title={Quantum Entanglement Growth Under Random Unitary Dynamics}, author={Adam Nahum and Jonathan Ruhman and Sagar Vijay and Jeongwan Haah}, journal={arXiv: Statistical Mechanics}, year={2016} }

Characterizing how entanglement grows with time in a many-body system, for example after a quantum quench, is a key problem in non-equilibrium quantum physics. We study this problem for the case of random unitary dynamics, representing either Hamiltonian evolution with time--dependent noise or evolution by a random quantum circuit. Our results reveal a universal structure behind noisy entanglement growth, and also provide simple new heuristics for the `entanglement tsunami' in Hamiltonian…
