• barrier is still several times larger than the thermal energy and the energy of a single 10 GHz photon. Conclusion We have presented an experimental study of a Josephson junction with an area of 60 μm2 and a critical current of 8.6 μA for application as a single photon counter in the microwave frequency

• photon counter in the microwave frequency range. We have measured the switching from the superconducting to the resistive state through the absorption of 10 GHz photons. The dependence of the switching probability on the signal power suggests that the switching is initiated by the simultaneous absorption

• -photon counter described in [4]. We study the possibility of detecting photons in the gigahertz frequency range using an aluminium Josephson junction with a suppressed critical current. The main requirement to this counter is an extremely large lifetime (thousands of seconds), orders of magnitude larger

• Kramers’ theory [32][33]. The exit of the particle from the well due to fluctuations does not lead to the instantaneous appearance of a final voltage at the Josephson junction, which can be seen in experiment as an increase of the noise immunity of the system. The principle of operation of a single-photon

• number of absorbed photons and only above-threshold signals can be detected. Also, special care must be taken to minimize the false switching events of the detector due to thermal fluctuations and macroscopic quantum tunneling. In this article the second approach is applied to a prototype of a single
