Superconducting Nanowire Single-Photon Detectors: From Integration to Application

Single photon detectors enable applications across multiple disciplines. In astronomy and biology, they allow sensing in photon-starved conditions, whereas in material science and optical ranging, they provide time-resolved measurements. In quantum information science, photons can function as heralds or flying qubits. Their detection dictates subsequent experimental steps, enabling the transfer of quantum information. Superconducting nanowire single photon detectors (SSPDs) offer a unique combination of performance metrics. They offer picosecond time resolution, near-unity detection efficiency, and sub-Hz noise counts across a broad wavelength range from the UV to infrared range.

In this webinar hosted by the Photonic Detection Technical Group, Samuel Gyger will present an overview of current advances in SSPDs. Dr. Gyger will present the integration into photonic circuits using homogeneous and heterogeneous approaches. We combine reconfigurable photonic circuits based on microelectromechanical systems with SSPDs. Utilizing transfer printing, we integrate detectors on various material platforms. Next, Dr. Gyger will present two applications of SSPDs in quantum communication and science: our work on entanglement distribution between remote nodes and the sideband thermometry of a novel opto-mechanical resonator with ultra-low phonon occupation.
