Single-photon detection with a Josephson junction coupled to a resonator

Abstract

We use semiclassical formalism to optimize a microwave single photon detector based on switching events of a current biased Josephson junction coupled to a resonator. In order to detect very rare events, the average time between dark counts ${\tau }_{\mathrm{dark}}$ should be maximized taking into account that the switching time ${\tau }_{\mathrm{sw}}$ should be sufficiently small. We demonstrate that these times can be tuned in the wide range by changing the junction parameters, and the ratios ${\tau }_{\mathrm{dark}}/{\tau }_{\mathrm{sw}}\sim 10^9$ can be achieved. Therefore, a junction-resonator arrangement can be used for detecting extremely low photon fluxes, for instance for searching galactic axions.
