Measurement of Noise Correlation Through Superconducting Josephson junctions

We demonstrate that it is possible to measure the time correlation of a Gaussian noise through the analysis of the escape times of Josephson junctions. To do so we construct the histogram – through Kernel estimation, of the collected data and we observe that the structure depends upon the duration of the correlation in noise. This paves the way towards the possibility to measure in situ noise correlation with a superconducting device.
