  1. Mode frequencies, lifetimes, and interaction strengths for the left qubit (a1), right qubit (a2), and bus mode (b). Uncertainties in the relaxation and coherence times reflect the fluctuations over the course of the experiment (about 3 months). Target χ values for qubit-cable coupling was 2 MHz. Qubit coherence times were lower and fluctuate more strongly than in non-network packages. Typical T1,2 times in qubits made in the same way but in packages without cable mount are reliably in the 50 μs to 100 μs range, limited by fabrication and sample holder material.
