Researchers successfully demonstrate prototype for space-based quantum-secured communication

Waterloo, Ont. (Wednesday, December 21, 2016) — Researchers from the Institute for Quantum Computing at the University of Waterloo in Canada are the first to transmit a quantum key securely from a source on the ground to a receiver on an aircraft. The uplink is a prototype for secure quantum communication and shows the viability of the team’s quantum communication satellite mission (QEYSSat) proposal.

Solving Tsirelson’s problem

Alice and Bob are on a game show. They each sit in isolation booths at either ends of the set and can’t communicate in any way. The game show host asks a number of questions.

From the judges’ perspectives, Alice and Bob appear to read each others’ minds.

Workshop tackles challenges of protecting businesses and governments from a quantum threat

Challenges to protecting information and systems from the massive processing power of quantum computers will be the focus of a workshop that the University of Waterloo’s Institute for Quantum Computing will co-host in Toronto next week.

The technology industry is now facing a Y2Q — years to quantum — challenge. The current deadline is estimated to be 10 years. All security dependent on existing standards is vulnerable.
