    Quantum Entanglement Demonstrated Aboard Orbiting CubeSat

    Article obtained from Photonics RSS Feed.

    An international research team led by the National University of Singapore (NUS) has generated and detected quantum entanglement onboard a CubeSat nanosatellite weighing less than 2.6 kg and orbiting Earth. CubeSats are low-resource, cost-effective satellites and are smaller than a shoebox.

    As a first step, the researchers needed to demonstrate that a miniaturized photon source for quantum entanglement could remain intact through the stress of launch and operate successfully in the harsh environment of space within a satellite that provides minimal energy. They examined every component of the photon-pair source that would be used to generate quantum entanglement to see if it could be made smaller or more rugged.
