One-shot entropies from thermodynamics

Thursday 5th December 2013 - 14:00 to 15:00
INI Seminar Room 2
Long before their use in information theory, entropies have been introduced in thermodynamics. One may therefore wonder whether thermodynamics could also provide some guidance for the definition of one-shot entropies. It turns out that this is indeed the case: starting from an operational definition of entropy for thermal systems in the one-shot regime, we obtain a sensible entropy measure with applications in one-shot information theory. In particular, it automatically satisfies the data processing inequality and a chain rule. In my talk, I will show some recent advances as well as challenges of this research programme.
