Low Rank Structure of the Reduced Transition Matrix
Cathy Li, Bruno Bertini, Katja Klobas +1
The influence-matrix formalism provides an alternative route to the classical simulation of quantum dynamics. Because influence matrices retain information only about the effective…
Initial State Memory in Finite Random Brickwork Circuits
Jakob Bannister, Katja Klobas, Colin Rylands +1
We ask under what conditions a finite brickwork circuit of random gates retains local information about the initial state. To answer this question we measure the averaged Frobenius…
Quantum State Designs from Minimally Random Quantum Circuits
Jonathon Riddell, Katja Klobas, Bruno Bertini
Random many-body states are both a useful tool to model certain physical systems and an important asset for quantum computation. Realising them, however, generally requires an expo…
Entanglement Negativity and Mutual Information after a Quantum Quench: Exact Link from Space-Time Duality
Bruno Bertini, Katja Klobas, Tsung-Cheng Lu
We study the growth of entanglement between two adjacent regions in a tripartite, one-dimensional many-body system after a quantum quench. Combining a replica trick with a space-ti…
