On behalf of the community here at the Institute for Quantum Computing (IQC), congratulations to the Government of Canada and the Canadian Space Agency on today’s announcement. The $80.9 million in funding to the Canadian Space Agency is an important investment in the development of new technologies that will benefit all Canadians for generations.

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.

“Weird.” Amusing.” “What’s with the cat?” These are all phrases that were heard at the Institute for Quantum Computing (IQC) on Thursday, February 23.

IQC PhD student Hemant Katiyar led the first experiment to violate the Leggett-Garg inequality on a three-level quantum system, demonstrating the possibility of larger violations than previously thought possible.

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.

The Natural Sciences and Engineering Research Council of Canada (NSERC) and the Canada Research Chairs (CRC) program has awarded more than $11 million to the University of Waterloo which includes $1.7 million to an affiliate of the Institute for Quantum Computing (IQC).

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

IBM Quantum Experience is used for the first time as an educational tool at IQC’s Undergraduate School for Experimental Quantum Information Processing (USEQIP).

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.
