Experiment 0: Flux Sweeping
A notebook that uses the SRS voltage source to sweep flux and record the resonator responce using the VNA.
**notebook name:** [experiment0.ipynb](experiment0.ipynb)
Experiment 1: Acquiring time-domain IQ data following the flux curve and varying the clearing tone frequency and power
**notebook name:** [experiment1.ipynb](experiment1.ipynb)
High level overview:
```python
v_arr, phi_arr, f_arr = from_flux_fit()
detuning = 0 # GHz
f_clearing_arr, P_clearing_arr = [], []
def find_mapped_resonance(phi):
global phi_arr, f_arr
phi_index = phi_arr[phi]
return f_arr[phi_index]
def find_resonance(phi, span):
f_guess = find_mapped_resonance(phi)
set_vna(f_guess, span)
f_phi = fit_vna_trace()
turn_off_vna()
return f_phi
for phi in phi_arr:
voltage = get_voltage(phi)
set_srs(voltage)
f_phi = find_resonance(phi)
f_drive = f_phi - detuning
set_drive_tone(f_drive)
for f_clearing in f_clearing_arr:
for P_clearing in P_clearing_arr:
set_clearing_tone(f_clearing, P_clearing)
acquire_IQ_data()
wait()
```
Set Up
### HPC:
Make sure you have SSH access to your HPC cluster
Set up SSH key-based authentication to avoid password prompts
Fill in the .env file with your HPC details
### Measurements:
1. Flux tuning curve of the resonator
---
## To Do:
- [ ] Test the rsync HPC back up mechanism
- [ ] Add resonator circle fit code
- [ ] Add the dynamic driving next mode code
- [ ] Add feature to upload saved data to HPC via Globus API
Experiment 2: Acquiring time-domain IQ data
A notebook that sets the LO at user specified parameters and takes the time domain IQ data with the Alazar card.
**notebook name:** [experiment2.ipynb](experiment2.ipynb)
