New protocol is a huge breakthrough for the future of quantum computers
Quantum computers will now have help tackling the central problem in their performance – noise.

Christine Muschik, assistant professor at the Institute for Quantum Computing (IQC) and the Department of Physics and Astronomy at the University of Waterloo, has been selected as a 2020-2022 CIFAR Azrieli Global Scholar.

Join us for an intimate conversation featuring IQC researchers. Our first guest is Professor Raymond Laflamme, interviewed by John Donohue. John and Raymond will have a conversation about research, careers, and life in quantum information science, followed by Q&A from the audience. Tune in Tuesday August 11 at 7:00pm Eastern Time.
New research shows that limited near-term quantum computers may be more powerful than they seem when solving a problem that is impossible for comparable classical computers.

The Institute for Quantum Computing (IQC) is saddened by the loss of Tom Brzustowksi. He was a great supporter of the institute having served on our Advisory Board since 2006, including as chair from 2006-2014.
The Dean of Science Award honours Master’s students in the Faculty of Science who demonstrate outstanding performance. We sat down with the latest winner, IQC researcher Patrick Daley from the Department of Physics and Astronomy, to learn more about his award-winning research.
How can two parties carry out a fair coin flip across a noiseless quantum channel? In 2007, Carlos Mochon proved a tantalizing result: he showed that fair quantum coin flipping is possible in principle, but he used a protocol that required a huge (exponential) number of communication rounds. In the twelve years since, despite some continued deep theoretical work on the problem, no improvements to the efficiency of Mochon's protocol have been made.
An experiment that began by testing the properties of quantum entanglement has led to the discovery of a new diagnostic tool that could help optometrists detect macular degeneration much earlier than was previously possible.
“In the future, I don’t think this is going to be replaced with a quantum computer,” said Rajibul Islam, faculty member at IQC and the Department of Physics and Astronomy, as he pointed towards his desktop computer.
Standard measurement units like the meter and the kilogram used to be defined by physical objects, such as a prototype bar and a platinum cylinder. As of May 2019, all measurement units are now defined by the cesium atom and the fundamental constants of the universe.
