| 14:00 - 15:00 Combinatorics and Computing Weekly Seminar Error Exponent for Classical-Quantum Channel Coding School MATHEMATICS The HSW (Holevo-Schumacher-Westmoreland) theorem characterizes the capacity of noisy quantum channels for the transmission of classical information. Since the works of Holevo (1998) and Schumacher-Westmoreland (1997) several questions regarding the problem of classical-quantum channel coding, including finite blocklength bounds, second-order analysis and strong converse bounds have been answered. Nevertheless, the optimal error exponent for the classical-quantum channel coding has remained as an open problem for more than two decades. In this talk, a new decoder and a new lower bound on the error exponent of classical-quantum channel ... 18:30 - 20:00 Algebraic Geometry Biweekly Webinar Hyperkahler manifolds and Lagrangian fibrations School MATHEMATICS This is mostly an introduction to and short survey of hyperkahler manifolds and Lagrangian fibrations, including some known results and some open problems. https://zoom.us/join Meeting ID: 9086116889 Passcode: 362880 Venue: , (Online) ... |
