| Summary:
Microwave driving is a ubiquitous technique for superconducting qubits
(SCQs), but the dressed states description based on the conventionally used
perturbation theory cannot fully capture the dynamics in the strong driving
limit. Comprehensive studies beyond these approximations applicable to
transmon-based circuit quantum electrodynamics (QED) systems are unfortunately
rare as the relevant works have been mainly limited to single-mode or two-state
systems. In this work, we investigate a microwave-dressed transmon coupled to a
single quantized mode over a wide range of driving parameters. We reveal that
the interaction between the transmon and resonator as well as the properties of
each mode is significantly renormalized in the strong driving limit. Unlike
previous theoretical works, we establish a non-recursive, and non-Floquet
theory beyond the perturbative regimes, which excellently quantifies the
experiments. This work expands our fundamental understanding of dressed cavity
QED-like systems beyond the conventional approximations. Our work will also
contribute to fast quantum gate implementation, qubit parameter engineering,
and fundamental studies on driven nonlinear systems.
