Quantum Simulation Of Semi-classical Rabi Model Under Extremely Strong Driving With Circuit QED System

Superconducting qubit stands as currently one of the most ideal platforms for quan-tum simulation,whereas Rabi model,having been investigated in various quantum ma-nipulation systems(NMR,Cavity QED,circuit QED)both in depth and in breadth,is the most basic model to describe the interaction between light and matter.However,under extremely strong driving or coupling,where Rotation Wave Approximation is invalid,it is exceedingly difficult to tap into the behavior of Rabi model in experiments.To that end,we designed a scheme to experimentally simulate semi-classical Rabi model un-der arbitrarily strong driving,and carried said experimental scheme in a 3D transmon system,demonstrating the bahavior of a two level system subject to a driving that is significantly stronger than its own energy difference.
