The power hidden in one single photon is unprecedented. But we need to find ways to harness that power. This meeting will discuss cutting-edge technologies paving the way for versatile and efficient pure single-photon sources and detection schemes with low dark count rates, high saturation levels, and high detection efficiencies. This meeting will gather the key players in the photonic industry pushing the development of these technologies towards commercializing products that harness the intrinsic properties of photons.
