Experiment finds way to increase photon efficiency for quantum communications

A team of researchers at the Institute for Quantum Computing (IQC) demonstrated a new type of on-demand single photon generator that can shape photons to increase their efficiency when used in a quantum network.

Next-generation communication networks will rely on the transmission of quantum information. Single photons, as carriers of quantum information, will play an integral role in building these future networks.

Faculty member Norbert Lütkenhaus has been named a Fellow of the American Physical Society. He is recognized for his “pioneering theoretical contributions to the fields of quantum secure communications and optical quantum information processing.”

The Institute for Quantum Computing is pleased to announce a call for entries to the Quantum Shorts flash fiction competition. The competition is open to stories up to 1000 words long that take inspiration from quantum physics and include the phrase “There are only two possibilities: yes or no”. The competition is free to enter, offering prizes of up to US $1500.

A light emitting diode (LED)-based spectrophotometer designed and implemented by Institute for Quantum Computing (IQC) researchers is the first demonstration of characterizing optical coatings using a simple, automated device.

New research chair in quantum error correction demonstrates continued leadership by IQC and Waterloo in the pursuit of a quantum computer and in the development of other quantum technologies.  

WATERLOO, Ont. (Thursday, September 14) The University of Waterloo, in collaboration with Mike and Ophelia Lazaridis, has launched a new $8-million research chair to further solidify Waterloo’s leadership in quantum information research.

Researchers in Canada have taken a significant step towards enabling secure quantum communication via moving satellites, as announced by the Canadian Government in April 2017.

Last year, research from the Institute for Quantum Computing (IQC) at the University of Waterloo and the Perimeter Institute for Theoretical Physics (PI) showed that in the quantum world, certain kinds of correlations do imply causation. This line of research has now expanded to the question of whether there are types of causal structures that exist in the quantum world but not in the classical world of our everyday lives.

Canada is headed for the quantum space race with a project from the University of Waterloo.

Waterloo’s Quantum Encryption and Science Satellite (QEYSSat) initiative, announced as part of the federal government’s recent investment into space-related emerging technologies, joins a global race to quantum cybersecurity via satellites.
