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.

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.

The detection of gravitational waves on earth

Public lecture by Bill Unruh, The University of British Columbia

On February 11, 2016 it was announced that gravitational  waves have been detected affecting an instrument on earth. In addition to the realization of a 100 year old prediction the astounding sensitivity of the detector demanded the approaching and overcoming of seemingly fundamental quantum limits on measuring the motion of 25Kg masses. Quantum mechanics is usually thought of applying only to the very small (zeptogrammes and nanometers).

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.

Relativistic Quantum Information North

The Relativistic Quantum Information North (RQI-N) Conference, hosted by the Institute for Quantum Computing (IQC), will bring together an interdisciplinary community of researchers at the interface of quantum information science and relativity.

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.
