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.

Jean-Philippe MacLean is in Germany discussing quantum science at the prestigious 66^th Lindau Nobel Laureate Meeting.

Leading the Quantum Innovation (QuIN) laboratory at the Institute for Quantum Computing (IQC), Na Young Kim aims to build large-scale quantum processors based on novel materials and advanced technologies.

Institute for Quantum Computing (IQC) Executive Director Raymond Laflamme talked quantum computing with Prime Minister Justin Trudeau during a tour of Perimeter Institute for Theoretical Physics (PI) on Friday, April 15, 2016. Their conversation went on to seed a social media sensation that garnered headlines around the world.

Imagine a movie showing particles in a gas moving and colliding with each other. Then when you play the movie backwards the velocity of the particles will be opposite, but their motion is still governed by the same laws of physics – we could just as well call the backwards film “forward” – there is no fundamental way to distinguish the arrow of time. This is called time-reversal symmetry.

Institute for Quantum Computing (IQC) Professor Thomas Jennewein has received a $500,000 contract from the Canadian Space Agency (CSA) to advance the crucial Detector Assembly subsystem of a Quantum Key Distribution (QKD) payload for the proposed Quantum Encryption and Science Satellite (QEYSSat) mission.

An international team of researchers from the University of Toronto, Griffith University (Brisbane), and the Institute for Quantum Computing (Waterloo) demonstrate "surrealistic" quantum trajectories in the lab.

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.

Researchers in Canada, the United States and Europe led by the National Institute of Standards and Technology in Boulder, Colorado and Institute for Quantum Computing alumnus Krister Shalm have ruled out classical theories of correlation with remarkably high precision. A group including Institute for Quantum Computing members Evan Meyer-Scott, Yanbao Zhang, Thomas Jennewein, and alumnus Deny Hamel built and performed an experiment that shows the world is not governed by local realism.

THEMUSEUM in downtown Kitchener is hosting LIGHT Illuminated, an exhibit with activities that include a race against light and laser maze.
