Functionality Needed:

At Zero Flux

• Find Resonances through Interfacing with VNA

• Use resonator_profiling.py to fit the resonances and record the stats

• Take a Power Sweep with VNA and DA for each resonance and record the power at which the resonance goes non-linear and power required for 1 photon

• Check for flux tunability through VNA and SMU

• Take a flux sweep with VNA and SMU

• Fit the flux curve and extract parameters of interest

Extra Functionality for NBR Devices:

• Check for QP trapping (i.e. Multiple Lorentzian peaks test)
• Power Sweep at finite flux
• Test for QP clearing using an LO, VNA and SMU (i.e. sharpening of resonance)

Extra Functionality for Dissipator Devices:

Extra Functionality for JPA:

Extra Functionality for TWPA:
