Some Information Theoretic Aspects of Reliable Communication With Transmitter Side Information
… channel. Our main result is a new extremal inequality as the underpinning mathematical structure for the MIMO Gaussian broadcast channel problem. In one special case, this inequality yields a generalization of the classical vector entropy-power inequality (EPI). In another special case, this …

Functional inequalities in quantum information theory
Functional inequalities constitute a very powerful toolkit in studying various problems arising in classical information theory, statistics and many-body systems. Extensions of these tools to the noncommutative setting have been introduced in the beginning of the 90's in order to study the …

Multiple-user quantum information theory for optical communication channels
… a conjecture on the minimum output von Neumann entropy. In the first part of this thesis, we evaluate the optimum capacity for free-space line-of-sight optical communication using Gaussian-attenuation apertures. Optimal power allocation across all the spatiotemporal modes is studied, in both the …

Entropy in Data Compression, Additive Combinatorics and Probability
… and its relationship with the conditional varentropy rate is established. Interestingly, the dispersion is different in reference-based and pair-based compression, and it is proved that the reference-based dispersion is in general smaller. Secondly, a discrete, asymptotic analogue of the …
