Large-scale simulations of Floquet physics on near-term quantum computers

Abstract: Quantum systems subject to periodic driving exhibit a diverse set of phenomena both of fundamental and technological interest. However, such dynamical systems are more challenging to simulate classically than their equilibrium counterparts. Here, we introduce the Quantum High Frequency Floquet Simulation (QHiFFS) algorithm as a method for simulating the dynamics of fast-driven Floquet systems on quantum hardware. Central to QHiFFS is the concept of a kick operator which transforms the system into a basis where… Show more

“…Discrete time crystals have been realized experimentally in cold atom systems and in condensed matter systems with a periodic laser pulse [13][14][15][16]. Building on the previous work, these many-body systems have been realized using real quantum computers and in quantum simulations [17][18][19]. Furthermore, there has been a rising theoretical interest in studying DTCs with longer periodic phases and systems, which map to higher dimensions (≥2) [20].…”
