PhD candidate Milica Banic is the 2022 recipient of the Xanadu Award for an Outstanding Publication by a PhD Student.
With support from Xanadu, the Faculty of Arts & Science and the Department of Physics have established this $5,000 scholarship, which is awarded to one or more PhD students in the Department of Physics in recognition of the publication of a peer-reviewed article in an academic journal on a topic related to quantum information and quantum optics.
This award is the result of a donation of $25,000 over five years from Xanadu, a Toronto-based start-up company with close ties to the Department of Physics. A number of former post-doctoral fellows, PhD students and undergraduate students are affiliated with Xanadu and Xanadu continues to work with U of T Physics faculty through the MITACS Program.
Due to their current and past relationships with the University of Toronto, Xanadu founder and CEO Christian Weedbrook says “we wanted to encourage students in the field of quantum information and quantum optics and to let them know that Xanadu, and many other quantum startups in Canada, exist when they graduate.”
Application requirements include a peer-reviewed article on a topic related to quantum information and quantum optics and a cover letter explaining the significance of the paper in one or two paragraphs.
Milica Banic was selected by the Xanadu Award Committee of the Department of Physics in winter 2022. She received the award for her paper "Generation of photon pairs by stimulated emission in ring resonators".
Milica describes the paper - "We study the generation of photon pairs by a nonlinear process called stimulated third order parametric down-conversion (TOPDC). We discuss some differences between this pair generation scheme and others which are commonly employed, and by calculating its efficiency in a microring resonator, we argue that it should soon be possible to demonstrate this process in integrated photonic devices."
When asked what this award means to her she says "Our hope is that publishing this work will lead to interest from the community in integrated TOPDC, which has not been seriously discussed in the literature. I especially hope to see efforts towards the design of platforms for TOPDC. Progress in this area could eventually make other TOPDC processes viable, which would open the possibility of generating different types of non-classical light for use in larger systems. I see this award as a sign that this work could indeed have the impact that we envision, which is very encouraging."

Amar Vutha among U of T's 33 new or renewed Canada Research Chairs
The program supports exceptional work across a wide variety of fields. At U of T, that includes everything from marine epidemiology and precision medicine to research into sustainable bioproducts.
Amar Vutha received a renewed Canada Research Chair in Precision Atomic and Molecular Physics.
With the renewal, Vutha's work goes on. He says, "someone needs to find lab-based evidence for that weird dark stuff that astronomers claim is all over the universe; and we still don't know why everything is made of matter rather than anti-matter. My students and I want to build more precise measuring tools -- atomic clocks and molecular gyroscopes -- to check if physics works".
When asked what this renewed research chair means to him he said "it implies a reassertion of faith in my group's research program. So I am grateful to the university and the Canadian physics community for continuing to support precision measurements as a way to discover fundamental physics."

Dr. Xiaoqing Zhong's paper has been chosen as an Editors' suggestion in APS Physical Review Applied
The project is a collaboration between U of T Physics Prof. Hoi-Kwong Lo and Prof. Li Qian's group in the Department of Electrical and Computer Engineering. Dr. Zhong was a co-supervised student.
Establishing secure encryption keys between any two users in a long-range communication network is important. Twin-field quantum key distribution (TFQKD), while promising for this application due to its tolerance to loss and its measurement-device-independent feature, has been limited to two users because of its requirement that phase stability of optical signals from any of the communicating user pairs be established regardless of their locations in the network. In this work, the authors demonstrate a TFQKD network by connecting three users in a Sagnac fiber ring, a configuration that provides inherent phase stability. This experiment suggests that the Sagnac TFQKD system is an effective and practical approach to implementing a long-range and secure communication network.

Professor Hoi-Kwong Lo Among most Productive and Impactful Authors
The list appeared in the paper "Quantum Cryptography Research: A Scientometric Assessment of Global Publications during 1992-2019" in the journal Science and Technology Libraries.
The study examined global “Quantum Cryptography” research on a set of quantitative and qualitative metrics to understand the status of research in the subject at global, national, institutional, and individual level. The analysis was based on publication data in the subject comprising a total of 10801 publications as indexed in the Scopus database covering the period 1992–2020.
The study provided a window to most productive countries, research organizations and authors in the subject, to most popular broad subject areas in research, to top modes of research communication, and in addition it describes the characteristics of highly cited papers. The study mapped the most productive countries, organizations, authors, and keywords in the context of collaborative research.
Professor Lo appears on page 15 under the list of "Quantum cryptography collaborative research networks – collaborative linkages among most productive authors, 1992–2019."
He says "I feel honoured by the result. And, I would like to thank the University of Toronto and my mentors, colleagues, collaborators and graduate students for their hard work and strong support. The result would not have been possible without them"
Professor Yong-Baek Kim Awarded 2022 Guggenheim Fellowship
