In a paper published in Physical Review Letters, PhD student Sascha Agne and colleagues experimentally realized a three-photon Greenberger-Horne-Zeilinger (GHZ) interferometer and observed genuine three-photon interference for the first time, bringing scientists one step closer to exciting applications in quantum 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. Neither knows what questions are being asked, or the answers the other gives. The judges are shocked that they provide the exact same answer more often than they should. From the judges’ perspectives, Alice and Bob appear to read each others’ minds.

A team lead by researchers from the Institute for Quantum Computing and the Department of Physics and Astronomy at the University of Waterloo has successfully detected the presence of single photons while preserving their quantum states.

Four professors from the University of Waterloo are among the new fellows of the Royal Society of Canada (RSC) announced today, peer-elected as the best in their field.

The fellowship of the RSC consists of individuals who have made outstanding contributions in the arts, the humanities, science, and Canadian public life.
