Analysis of Josephson junctions switching time distributions for the detection of single microwave photons

A. S. Piedjou Komnang, C. Guarcello, C. Barone +5

We investigate an optimal scheme for the detection of single microwave photons by a Josephson junction through the analysis of its switching times distribution. The proposed analys…
