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.
IQC PhD student John Donohue, along with Elie Wolfe from the Perimeter Institute of Theoretical Physics, has determined the required complexity of a quantum system and how many bits of shared classical information are needed between two parties to generate a general probability distribution with a known set of quantum correlations.
Focused on quantum materials, Tsen looks to integrate low-dimensional materials that exhibit exotic quantum phenomena into novel electronic devices.
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.
