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"
