Abstract

The current challenge of quantum photonic is to realize integrated circuits that monolithically combines light sources, optical modulators, storage units, and light detectors. Lithium niobate (LN) waveguides has emerged as one of the key platforms of photonics quantum technologies [1]. Due to mature technology of waveguide fabrication, efficient properties for light control and compatibility with the existing telecommunication infrastructure, LN is at the heart of many quantum components (light sources, modulators, coherent wavelength convertors and quantum memories). Superconducting single-photon detector (SSPD) is relatively simple architecture for the realisation in a waveguide configuration and has been demonstrated on several technological platforms [2].
