Quantum simulation of low dimensional Floquet systems — •Simon Strnad, Filip Wudarski, and Andreas Buchleitner — Physikalisches Institut, Albert-Ludwigs-Universität Freiburg

Floquet theory allows for an accurate, non-perturbative treatment of a large class of physical scenarios with explicit time dependence, with applications, e.g., in light-matter interaction, mesoscopic and open quantum systems. Since Floquet theory relies on the time periodicity of the Hamiltonian (H(t)=H(t+T)), it represents a natural link between autonomous problems and those with non-periodic time dependence.

Given recent progress in the simulation of autonomous quantum systems on quantum computing platforms, we extend these approaches to Floquet problems. We demonstrate how to map the low dimensional unitary Floquet evolution on a set of easily implementable gates, and discuss potential limitations of the accuracy, which arise from hardware restrictions.
