Quantum Sensing

We are interested in exploiting quantum technologies such as entangled photon sources and single photon detectors, for photonic sensing. Applications are emerging for sensing and imaging as well as probing molecular dynamics in regimes unattainable with conventional (classical) approaches. We are also pursuing the application of quantum mechanical tools and techniques for the certification of quantum technologies, devices and systems.
