dc.descriptionWe investigate phase-sensitive interference effects in a periodically $\sin(2πf_{\rm rf} t)$-driven, artificial two-state system connected to a microwave resonator at $f_{LC} \simeq 800$ MHz. We observe two kinds of multiphoton transitions in the two-state system, accompanied by: 1) Several quanta from the drive at $f_{\rm rf}$ and 2) one quantum at $f_{\rm rf}$ and several at $f_{LC}$. The former are described using phase-sensitive Landau-Zener transitions, while the latter are discussed in terms of vibronic transitions in diatomic molecules. Interference effects in the vibronic transitions governed by Franck-Condon coefficients are also considered.
