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.

IQC postdoctoral fellow Chris Herdman led a demonstration of area law scaling of entanglement entropy in a real quantum fluid for the first time.

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.

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.

New Haven, Conn. – Buoyed by a $3 million federal grant, a Yale University-led experiment will explore key questions about the tiny particles called neutrinos — and potentially improve the way we monitor and safeguard nuclear reactors in the process.

The U.S. Department of Energy grant from the Office of High Energy Physics will be used to build a first-of-its-kind, short-distance detection device for the Precision Oscillation and Spectrum Experiment (PROSPECT), a project involving 68 scientists and engineers from 10 universities and four national laboratories.

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.
