Justin Trudeau, Premier ministre du Canada, peut expliquer en un peu plus de 30 secondes ce qu’est l’informatique quantique. Le pouvez-vous? Vous aurez bientôt la possibilité d’en savoir plus sur la science et la technologie de l’information quantique.
Researchers have found a new method to grow high-quality, defect-free material for nanowire p-n junctions, resulting in better electrical contacts for quantum light-emitting diode (LED) devices.
A professor at the University of Waterloo is the recipient of a 2016 Canadian Association of Physicists (CAP) Herzberg Medal for his outstanding early-career achievements in condensed matter physics.
Researchers from the Institute for Quantum Computing (IQC) and the Department of Applied Mathematics at the University of Waterloo have developed a universal method to manipulate quantum systems while minimizing their exposure to noise. Unlike related control methods that are designed for a particular physical setting, this new method is universal and can be applied regardless of the type of experimental set-up.
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.
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.
