Outline of Final Research Achievements

Single-photon detection is a requisite technique in quantum-optics experiments in both the optical and the microwave domains. However, the energy of microwave quanta are four to five orders of magnitude less than their optical counterpart, making the efficient detection of single microwave photons extremely challenging.
We have succeeded in detecting a single microwave photon propagating through a waveguide by using a coupled system of a superconducting microwave resonator and a superconducting qubit. We attain a high single-photon detection efficiency of 66±6 % with a low dark-count probability of 1.4±0.1 % and a photon counting rate of 1.3 MHz.
