Here, we demonstrate a key component of such a circuit, a waveguide single-photon detector. Our detectors, based on superconducting nanowires on GaAs ridge waveguides, provide high efficiency (similar to 20%) at telecom wavelengths, high timing accuracy (similar to 60 ps), and response time in the ns range and are fully compatible with the integration of single-photon sources, passive networks, and modulators.
