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