Quantum Today: Dimension Reductions in Quantum Key DistributionExport this event to calendar

Thursday, August 19, 2021 — 12:00 PM EDT

Join Twesh Upadhyaya, MSc student at the University of Waterloo’s Institute for Quantum Computing (IQC) and Department of Physics & Astronomy, 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 IQC and Department of Physics and Astronomy 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.
