The entropy function plays a central role in information theory. Constraints on the entropy function in the form of inequalities, viz. entropy inequalities (often conditional on certain Markov conditions imposed by the problem under consideration), are indispensable tools for proving converse coding theorems. In this expository article, we give an overview o...
Student researchers are an indispensable part of the IEEE Information Theory Society (ITSoc). If academic research is analogized with a communication system, then our faculty body constitutes the codebook, and our student body represents the codewords traveling through the medium of time, taking with them our most consequential messages and research outputs...
It is well-known that nondegenerate quantum error correcting codes (QECCs) are constrained by a quantum version of the Hamming bound. Whether degenerate codes also obey such a bound, however, remains a long-standing question with practical implications for the efficacy of QECCs. We employ a combination of previously derived bounds on QECCs to demonstrate tha...
This drawing was a blueprint for a small quilt that was added to the mathematics/art installation Mathemalchemy (about which more information can be found at mathemalchemy.org).
Few technologies have been as transformative as quickly as the mobile Internet, characterized by the global 4G and 5G cellular networks, as well as pervasive WiFi. Few engineering disciplines have benefited as much from strong theoretical underpinnings as has the wireless communications field, whose origins in and continuing partnership with information theo...
