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.



Fig 5: Microwave photon population measured inside the resonant cavity by means of qubit spectroscopy.
