Superconducting Quantum Computing » Runs

I checked the GDS file that the Rigetti team sent, and I found the dimensions are a bit modified from what I sent. But the parameters are not hugely changed(actually they got slightly better!), so it would be okay to use it.
One chip(A2-c1-b1) has very low inductance, so has large qubit frequency(7.66 GHz) and low coupling(<2 kHz). I don’t think it will work as a qubit.

The other chip(A2-g1-b1) is fine. The specs are

Qubit freq: 4.89 GHz
Qubit anharmonicity: 72.86 MHz

Readout freq: 6.211 GHz

Qubit-fundamental coupling : 85 kHz
Qubit-readout coupling : 3.6 MHz

Fundamental mode Q-factor: ~10^6
Readout mode Q-factor: ~10^5

We found RI-2 cavity,
f= 2.985769709 GHz
Q ~ 1e8
temp of mixing chamber = 53 mK

Some more accurate estimation of TI-2 Q from decay:
decay time from -50 dB to e times (green line) = 32 ms
Q = pi * 3E+9 * 32E-3 = 3E+8
Also attached raw data in "decay.csv"

We found the resonance of RI-1,
freq = 2.985951150 GHz
Mixing chamber temperature = 65 mK (It is increased a little bit because we activated the switch.)

estimation of TI-1 Q from decay (slightly better than TI-2)
decay time from -64 dB to e times (green line) = 39 ms
Q = pi * 3E+9 * 39E-3 = 3.67E+8
Attenuation through the cavity is ~15 dB higher.
Also attached raw data in "decay_RI-1.csv"

CW measurement of chi_0 shift of fundamental mode of RI-2 cavity.
High power(20dBm, black)
Low power(-10dBm, blue)

chi_0 shift = 58.89 Hz

Tried to test pulsed setup with new switches: measured Pappas' qubit readout. As expected, power levels went down by 10 dB because of new additional attenuation.
