Superconducting Qubit in a 3D Resonant Cavity
Fig 1: Half
resonant cavity in aluminum with qubit inside. Cavity and qubit were fabricated by TII (www.tii.ae)
Fig 2: Resonant cavity with qubit inside mounted on the LNF dilution refrigerator
Fig 3: Transmission of the cavity with the qubit inside as a funcion of VNA power and frequency. Above -5 dbm the bare cavity frequency appears.
Fig 4: Chevron plot showing the Rabi oscillation as a function of the frequency of the qubit control-pulse and time duration of the pulse itself.
