Single-photon detection is essential to many quantum-optics experiments. Although various kinds of single-photon detectors are available in the optical domain, the detection of a single microwave photon remains a challenging task due to its correspondingly small energy. In this presentation, we demonstrate an efficient and practical single microwave-photon detector based on the superconducting quantum circuits.
