Commercialisation of efficient single-photon detectors for telecom applications imminent
Sending and receiving quantum information over long distances using single photons at telecommunication wavelengths will underpin innovations in remote sensing applications and quantum information processing. The EU-funded NP-SPAD project will develop a device scheme that leverages single-photon avalanche diodes (SPADs) composed of semiconductor materials that will be operating at 1.55 µm. The aim is to improve photon detection efficiency by 20 % and significantly reduce the dark count rate compared to the commercial Geiger-mode avalanche photodiodes. If successful, the project will significantly foster the development and commercialisation of high-performance semiconductor-based SPADs, putting the EU at the forefront of cutting-edge technology in single-photon detection.
