Superconducting circuit quantum electrodynamics(QED)architecture composed of superconducting qubit and res-onator is a powerful platform for exploring quantum physics and quantum information processing.By employing tech-niques developed for superconducting quantum computing,we experimentally investigate phase-sensitive Landau-Zener-Stückelberg(LZS)interference phenomena in a circuit QED.Our experiments cover an extensive range of LZS transition parameters and demonstrate the LZS induced Rabi-like oscillation as well as phase-dependent steady-state population.
