Quantum spectroscopy using entangled photons

The field of quantum optics is undergoing massive growth, which is enabling a host of new applications within the field. The quantum nature of light allows us to push the limits of various techniques including, but not limited to, spectroscopy, interferometry, sensing and imaging. At the heart of these is a need for a reliable source of entangled photons. The quantum revolution is underpinned by ultrashort pulse duration lasers, and especially fiber lasers. Ultrafast fiber lasers provide reliable ultrashort pulse durations at an unprecedented price point.
