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.

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.

John Fish could end up travelling to the Silicon Valley later this week as the winner of the Breakthrough Junior Challenge. He is one of the 15 finalists out of more than 2,000 students from 86 countries, and only one of two Canadians to get this far in the annual challenge that invites students, ages 13-18, to share their passion for math and science with the world through video.

Computer scientists, including Institute for Quantum Computing (IQC) members John Watrous and Richard Cleve have long been looking at protocols where quantum communication offers an advantage compared to the classical case. However technology hasn’t progressed as quickly, so researchers had previously been unable to implement the protocols.

Infinity – the mathematical notion of no limits. Our physical world has many limits. Yet mathematically infinity is reality.
