    Entanglement demonstration on board a nano-satellite
    (The Optical Society, 2020-07-20) Villar, A.; Lohrmann, A.; Bai, X.; Vergoossen, T.; Bedington, R.; Perumangatt, C.; Lim, H. Y.; Islam, T.; Reezwana, A.; Tang, Z.; Chandrasekara, R.; Sachidananda, S.; Durak, Kadir; Wildfeuer, C. F.; Griffin, D.; Oi, D. K. L.; Ling, A.; Electrical & Electronics Engineering; DURAK, Kadir
    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.

    Entanglement demonstration on board a nano-satellite
    (Optica Publishing Group, 2020) Villar, A.; Lohrmann, A.; Bai, X.; Vergoosen, T.; Bedington, R.; Perumangatt, C.; Lim, H. Y.; Islam, T.; Reezwana, A.; Tang, Z.; Chandrasekara, R.; Sachidananda, S.; Durak, Kadir; Wildfeuer, C. F.; Griffin, D.; Oi, D. K. L.; Ling, A.; Electrical & Electronics Engineering; DURAK, Kadir
    Polarization entangled photon-pairs are generated and detected onboard a 3U CubeSat in low-Earth orbit that violate Bell’s inequality with a CHSH parameter of 2.60 ± 0.06. These results pave the way for space-based quantum networks.
