Theorists from Perimeter and experimentalists from the Institute for Quantum Computing have found a new way to test whether the universe is quantum, a test that will have widespread applicability: they’ve proven the failure of noncontextuality in the lab.

What does it mean to say the world is quantum? It’s a surprisingly difficult question to answer, and most casual discussions on the point are heavy on the hand-waving, with references to cats in boxes.

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

WATERLOO, Ont. (Friday, May 20, 2016) – What once took months by some of the world’s leading scientists can now be done in seconds by undergraduate students thanks to software developed at the University of Waterloo’s Institute for Quantum Computing (IQC), paving the way for fast, secure quantum communication.

Researchers at the Institute for Quantum Computing (IQC) at the University of Waterloo developed the first available software to evaluate the security of any protocol for Quantum Key Distribution (QKD).

AMSTERDAM: Europe’s top researchers, government and industry leaders gathered today at the Quantum Europe 2016 conference in Amsterdam to discuss a comprehensive strategy for quantum technology development and commercialization.

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.

A team led by Professor Thomas Jennewein at the University of Waterloo’s Institute for Quantum Computing (IQC) has successfully completed the development of the crucial Acquisition, Pointing and Tracking (APT) fine pointing system for a future Quantum Key Distribution (QKD) satellite payload.
