Watch a 24-minute conference talk from the 18th Theory of Quantum Computation Conference (TQC 2023) exploring quantum mechanical advantages in particle behavior. Learn about groundbreaking research demonstrating how quantum mechanics enables higher probabilities of finding particles at distant positions compared to classical mechanics predictions. Delve into the mathematical relationship between this quantum advantage and quantum backflow, including improvements to the Bracken-Mellow constant bounds. Examine various generalizations of these findings presented by David Trillo, with supporting research available in the linked arXiv paper. The presentation was delivered at the University of Aveiro as part of TQC's mission to advance theoretical quantum information science through collaborative discussion of cutting-edge discoveries.
