Fig. 6: Distribution of times between sequential switchings of the SPD at three various temperatures.
From: Detection of single-mode thermal microwave photons using an underdamped Josephson junction
The experimental data (dots) are fitted by \(\exp (-t/\tau )/\tau\) (dashed curves) without any fitting parameters with the mean switching time τ directly taken from experimental data. Good agreement between fitting and experiment is observed at 21 mK and 80 mK cavity temperatures. One can note super-Poissonian distribution at intermediate cavity temperature 47 mK. Inset: The τ to σ ratio vs cavity temperature, showing deviation from Poissonian statistics.
