摘要
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-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.
