Abstract
The monolithic integration of single-photon sources, passive optical circuits, and single-photon detectors enables complex and scalable quantum photonic integrated circuits, for application in linear-optics quantum computing and quantum communications. Here, we demonstrate a key component of such a circuit, a waveguide single-photon detector. Our detectors, based on superconductingnanowires on GaAs ridge waveguides, provide high efficiency (~ 20%) at telecom wavelengths, high timing accuracy (~ 60 ps), and response ...File in questo prodotto:
