Toward the quantum Internet: Helmy wins funding from Connaught Global Challenge Award

Professor Amr Helmy.Dec. 7, 2015

Following the horrific attacks on Paris and other cities in November, speculation swirled that the plotters may have been using smartphone apps to encrypt their communications. It would take powerful computer, much faster than those commercially available today, to identify, intercept and decrypt such messages.

Simultaneously, as more people and businesses move crucial operations online, it’s increasingly important to ensure security, privacy and confidentiality of information.

Quantum computing, and quantum cryptography, harness the physical laws of quantum mechanics to provide both speed and security improvements many orders of magnitude better than today’s state-of-the-art.

“A technological platform that provides a significant leap forward is sorely needed,” says Professor Amr Helmy of The Edward S. Rogers Sr. Department of Electrical & Computer Engineering. “My personal vision is for a quantum Internet that can go beyond quantum-based security—that can afford distributed quantum information processing, where quantum computers connected by quantum communications.”

Helmy is leading a team that received funding from the Connaught Global Challenge competition to gather a critical mass of quantum Internet researchers and identify pressing research questions. The group includes investigators from across the University of Toronto, including in ECE, Physics, and Chemistry, as well as industry partners from Nippon Telegraph and Telephone in Japan and Burnaby, B.C.-based quantum-computing company D-Wave Systems.

One of the group’s first objectives, says Helmy, will be to study how quantum states encoded in light, as photons, can robustly exchange information, with quantum states generated and manipulated in matter, as ions.

“Currently there’s no robust way to couple quantum states of the two systems—photons and ions—whereby one can share the generated quantum states between different network nodes,” says Helmy. “While there are promising approaches out there, they mostly lack the practical finesse, which propels them to fuel demonstrations out of the lab and into the field.”

The Connaught Global Challenge Award was established in 2011 to support interdisciplinary approaches to tackling problems of global significance. It is furnished by the University of Toronto’s Connaught Fund, founded in 1972 when U of T sold the Connaught Medical Research Laboratories for $29 million. Connaught is the largest internal university research funding program in Canada.
