Bichromatic Driving in Floquet Qubits

ORAL

Abstract

We study bichromatically driven single and coupled qubit systems for their application in single and two-qubit Floquet gates. Using the Floquet theory framework, we compare the full numerical calculation of quasienergies with the ones obtained analytically through rotating wave approximation and generalized Van-Vleck perturbation theory. Floquet qubits have been proposed to have dynamically induced high coherence lifetime sweet spots. We extend that argument to the case of bichromatic driving and observe dynamical sweet regions. We apply the bichromatic Floquet theory to superconducting fluxonium architecture to study single and two qubit gates.
