Le vendredi 15 avril 2016, Raymond Laflamme, directeur général de l’IQC, a parlé d’informatique quantique avec le Premier ministre Justin Trudeau au cours d’une visite de l’Institut Périmètre de physique théorique. Leur conversation a suscité dans les médias sociaux un mouvement qui a fait les manchettes dans le monde entier.

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.

Entanglement is an extremely strong correlation that can exist between quantum systems. These correlations are so strong that two or more entangled particles have to be described with reference to each other, even though the individual objects may be spatially separated.

It has been shown that even if two uncorrelated quantum systems that don’t know anything about each other can still become entangled in a quantum vacuum without being limited by the speed of light.

Researchers from the Institute for Quantum Computing at the University of Waterloo and the National Research Council of Canada (NRC) have, for the first time, converted the colour and bandwidth of ultrafast single photons using a room-temperature quantum memory in diamond.

What if checking for monsters under your bed doomed a parallel you to a grisly end? A story that explores this fear of a girl aged six and three quarter years has won the 2015 Quantum Shorts international competition for flash fiction inspired by quantum physics.

Researchers have successfully integrated an on-demand light source in a silicon-based chip, the first fully integrated quantum optics approach that is compatible with current technology in the semiconductor industry, such as existing computer processors and memories.

/*-->*/ Five of Canada’s leading science outreach organizations launch Innovation150, a national program that celebrates our country’s innovative past and sparks ideas and discoveries to propel our future.

Innovation150 is an interactive, year-long celebration of Canadian innovation that will offer cutting-edge opportunities for youth, families, and communities across the country to experience innovation first-hand.

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.
