Prethermalization, shadowing breakdown, and the absence of Trotterization transition in quantum circuits
Marko Znidaric
One of the premier utilities of present day noisy quantum computers is simulation of many-body quantum systems. We study how long in time is such a discrete-time simulation represe…

Integrability is generic in homogeneous U(1)-invariant nearest-neighbor qubit circuits
Marko Znidaric, Urban Duh, Lenart Zadnik
Integrability is an exceptional property believed to hold only for systems with fine-tuned parameters. Contrary, we explicitly show that in homogeneous nearest-neighbor qubit circu…

Inhomogeneous SU(2) symmetries in homogeneous integrable U(1) circuits and transport
Marko Znidaric
Symmetries are important for understanding equilibrium as well as nonequilibrium properties like transport. In translationally invariant extended systems one might expect symmetry…
