One of the tasks that quantum computing promises is algorithmic speedups over classical computing for certain types of problems – one of which is quantum searching. To achieve this, it’s important to build a robust quantum memory, more specifically, a memory that can store information which can be addressed quantum mechanically.

University of Waterloo researchers performed a lab demonstration proving the feasibility of Quantum Key Distribution over a satellite uplink.

In an emulated environment for performing QKD, a team of researchers analyzed the impact of the optical loss that occurs between the photon source and the satellite receiver. They successfully generated a secure key using algorithms tailored for a satellite receiver, an important step towards extending the distance of ultra-secure communications.

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.

THEMUSEUM in downtown Kitchener is hosting LIGHT Illuminated, an exhibit with activities that include a race against light and laser maze.

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.

John Fish could end up travelling to the Silicon Valley later this week as the winner of the Breakthrough Junior Challenge. He is one of the 15 finalists out of more than 2,000 students from 86 countries, and only one of two Canadians to get this far in the annual challenge that invites students, ages 13-18, to share their passion for math and science with the world through video.

Computer scientists, including Institute for Quantum Computing (IQC) members John Watrous and Richard Cleve have long been looking at protocols where quantum communication offers an advantage compared to the classical case. However technology hasn’t progressed as quickly, so researchers had previously been unable to implement the protocols.

Researchers from the Institute for Quantum Computing (IQC), led by Professors Kyung Soo Choi and Thomas Jennewein, both faculty members with the Department of Physics & Astronomy at the University of Waterloo, received funding from the Korea Institute of Science and Technology (KIST) to develop critical building blocks of a quantum network.

Infinity – the mathematical notion of no limits. Our physical world has many limits. Yet mathematically infinity is reality.

Sophia Antipolis, 08 October 2015: The third ETSI/IQC workshop, organized by ETSI and the Institute for Quantum Computing, Waterloo, Canada, was hosted by SK Telecom in Seoul, Korea, from 5 to 7 October 2015.
