Researchers test new approach to quantum-secured communication in space
Researchers from Canada and the United Kingdom will test a new approach for secure communication using satellite-based quantum technology.
Led by Thomas Jennewein, a faculty member in the Department of Physics and Astronomy and the Institute for Quantum Computing, researchers at the University of Waterloo are developing the Quantum Encryption and Science Satellite (QEYSSat), with a quantum key distribution payload that will allow the transmission of unbreakable keys for securing information.
The Waterloo team, which is leading the project, will closely collaborate with its Canadian partners Honeywell, the Canadian Space Agency, and researchers at the University of Calgary on demonstrating a novel quantum protocol onboard the QEYSSat mission.

An international research team, including UCalgary quantum physicists, has taken a big step toward building a high-performing, scalable “quantum internet.”
A functional quantum internet would dramatically change the fields of secure communication, data storage, precision sensing and computing.
In such a network, information stored in quantum bits, or qubits (the basic unit of quantum information) is shared, or teleported, over long distances.
“High-fidelity” (high quality) quantum teleportation of photons (elementary particles of light) is essential for secure long-distance communications and a practical quantum internet.
