We cordially invite you to our next CASA Invited Talk on July 21, 2026. Talks typically run for about an hour and are followed by an open discussion with the audience. The talks aim to encourage dialogue and open new perspectives in cybersecurity research.
When: July 21, 2026, 2 PM
Where: Building MC, Open Space (ground floor)
Online Participation: Zoom
Abstract: In this talk I will present a quantum algorithm for the Extrapolated Dihedral Coset Problem (EDPC) — a quantum variant of the Learning with Errors problem. The algorithm has quasi-polynomial time and sample complexity, which is the fastest way to solve EDCP for some interesting parameters. I will touch upon challenges in extending this result to the ring- and module- setting. The talk is largely based on the joint work with Shi Bai, Hansraj Jangir, Tran Ngo, and William Youmans.
