2021-02-19 Seminar Report

On 17th February, we had Ryusuke Hamazaki (from RIKEN Hakubi and iTHEMS) talking about the recent studies on the large deviation principle in our journal club of the Information Theory Study Group.
He started off by demonstrating Bernoulli's process and how to compute the large deviations, and then defined the Level 2.5 large deviations in Markovian jump process, thereby providing the derivation of a recently proposed inequality (the thermodynamic uncertainty relation). Finally, he explained possible extensions to quantum systems. The talk received numerous questions in every single part, specifically from those interested in the derivation and application of the Level 2.5 large deviation. Thanks, Ryusuke, for the great and inspiring talk!
