    Object Tracking and Identification by Quantum Radar





    Entanglement; as a Resource for Communication and Sensing - Kadir Durak (Özyeğin University, Turkey) ABSTRACT: Entanglement is one of the miracles of quantum physics which does not only fascinate with its counter intuitive nature, but also has practical applications in the fields of cryptography, computation and sensing. The commonly used quanta for entanglement are the photons due to their non-local coherence and easy manipulation in atmospheric and fiber channels. We analyze the emission rate, profile and collection optics dependency on brightness of entangled photons created within a nonlinear Beta-BBO crystal via spontaneous parametric down conversion process. We show that the brightness of down-conversion is under-estimated in the literature but the asymmetric emission profile of down converted photons limits the collection efficiency. Such a bright source can be used for sensing applications like position and velocity acquisition of distant object using time, polarization and momentum correlations of entangled photons, i.e. quantum radar. In this talk, the proof-of-principle experimental results of quantum radar concept will be presented and some possible limitations will be elaborated.

    Entanglement demonstration on board a nano-satellite

    Global quantum networks for secure communication can be realized using large fleets of satellites distributing entangled photon pairs between ground-based nodes. Because the cost of a satellite depends on its size, the smallest satellites will be most cost-effective. This Letter describes a miniaturized, polarization entangled, photon-pair source operating on board a nano-satellite. The source violates Bell’s inequality with a Clauser–Horne–Shimony–Holt parameter of 2.60±0.06. This source can be combined with optical link technologies to enable future quantum communication nano-satellite missions.
