From: Optimizing qubit performance through smoothing techniques

Three signals are presented for fixed voltage − 0.05 V (upper picture), 0.05 V (middle picture), 0.15 V (bottom picture), each obtained through smoothing techniques. Throughout the spectra, the voltage is held constant for consistent comparison. On the left side of each subplot is smoothed two-tone spectroscopy transmission signals are depicted using lowess smoothing, revealing three distinct lines. These lines correspond to different voltage conditions, with voltage held constant across the spectra.
