Raw data : Observation of two-mode squeezing in a traveling wave parametric amplifier

The raw data used to generate figures presented in the articles is available as qcodes datasets. Fig 2 The 100 million quadrature points used to construct statistics in figure 2 are stored at 10 datasets with ids 1 to 10, each containing 10 million points. The data was split in multiple databases to ease storage and processing. Fig 3 The pump phase sweep in figure 2 was recorded at 25 points from 0 to pi. Each sweep step is stored as a dataset in the database starting from run id 11 to 35, corresponding to 0 to pi in order. Fig 4 The quadratures recorded at delta values 20, 50, 100, 150 and 200 are stored with run id 36 to 40, respectively. Fig SNTJ gain calibration The noise spectrum as a function of voltage applied to SNTJ is stored for frequencies corresponding to the delta values 20, 50, 100, 150 and 200, from run id 41 to 45, respectively.
