Quantum key distribution gets ready for satellite uplinks
University of Waterloo researchers performed a lab demonstration proving the feasibility of Quantum Key Distribution over a satellite uplink.
In an emulated environment for performing QKD, a team of researchers analyzed the impact of the optical loss that occurs between the photon source and the satellite receiver. They successfully generated a secure key using algorithms tailored for a satellite receiver, an important step towards extending the distance of ultra-secure communications.
