Experiments carried out using the superconducting circuit quantum electrodynamics architecture demonstrate phase-sensitive Landau-Zener-Stuckelberg interference phenomena, confirming LZS-induced Rabi-like oscillations and phase-dependent steady-state populations.
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-Stuckelberg (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.
