Join Twesh Upadhyaya, MSc student at the University of Waterloo’s Department of Physics & Astronomy and Institute for Quantum Computing (IQC), in conversation with scientific outreach manager John Donohue. They’ll discuss his latest journal article entitled “Dimension Reductions in Quantum Key Distribution for Continuous- and Discrete-Variable Protocols” published in Physical Review X Quantum on May 24. His team, led by Department of Physics and Astronomy and IQC faculty member Norbert Lütkenhaus, explore the security analysis of quantum key distribution, a quantum-enabled technology that allows for secure long-distance encrypted communication. In their recent result, they developed a new method to analyze these problems by turning an infinite-dimensional problem into one with a limited number of dimensions, making them much easier to study. This method opens the door to rigorously studying a wide variety of quantum security approaches.
Quantum Today is an exciting seminar series that pulls it themes from recently published scientific articles. Join us as we sit down in conversation with researchers to talk about their work and its impact.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Indigenous Initiatives Office.
