  1. The wire length is denoted by lW. RW is the room temperature resistance of the wire estimated from the total circuit resistance. The readout resonator frequencies fr and transition frequencies f01 are obtained from spectroscopy. fcalc. corresponds to the harmonic estimate of the circuits resonance. The lifetimes are obtained by time-domain measurements.
