Single photon counting, based on single photon sources and detectors, is a key ingredient for certain applications aiming at new quantum information technologies. Quantum cryptography, quantum radiometry, distributed quantum computing, as well as adjacent technologies such as biomedical and astronomical imaging, and low power classical communication also rely on single-photon technology. This paper reviews the present status of single photon sources and related counting measurement techniques, based on correlated (or heralded) photons in parametric down-conversion, and their possible impact on the above mentioned technologies, as well as an assessment for photon standards in the future.

A significant variety of photonic devices is required for the implementation of quantum sensors, computers and communication networks. This presentation will describe the current state-of-the-art and future possibilities for key photonic devices that enable quantum technologies, such as photon sources, photon detectors, optical amplifiers, electro-optic modulators and paths towards the integration of these devices into compact, highly functional components. Specific requirements on these devices that come from quantum technology demands will be explored and technology solution approaches will be described. We will include examples of devices being developed at Freedom Photonics as well as in other leading quantum technology organizations.
