On Tuesday, October 12, at 6 a.m. CDT, a quantum communications experiment was launched into low orbit around Earth from the International Space Station (ISS). A collaborative experiment of the University of Illinois Urbana-Champaign and the University of Waterloo, CAPSat (Cool Annealing Payload Satellite) contains single-photon detectors, which can be used as receivers for unhackable quantum communications.
