10:22 PM Superconducting Quantum Computing Task #23809: DR1_Run_6 - Measure qubit from McDermott
With the above new settings I think we can observe two-photon transition. I've just finished qubit scan vs. frequency...
08:46 PM Superconducting Quantum Computing Task #23809: DR1_Run_6 - Measure qubit from McDermott
Update:
we were focused on hardware problems last 2 days:
1) we found that I-Q corrections for vector signal genera...
