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).
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 new venture was made possible by generous support from the Board of Governors of the IT Society, and I appreciate their vision and leadership. IEEE BITS looks to publish tutorial articles that view vibrant research areas like machine learning, wireless, quantum information science, and blockchains through an information-theoretic lens. We are supporte...
Privacy has become an emerging challenge in both information theory and computer science due to massive (centralized) collection of user data. In this article, we overview privacy-preserving mechanisms and metrics from the lenses of information theory, and unify different privacy metrics, including f-divergences, Rényi divergences, and differential privacy (...
Group testing is the technique of pooling together diagnostic samples in order to increase the efficiency of medical testing. Traditionally, works in group testing assume that the infections are i.i.d. However, contagious diseases like COVID-19 are governed by community spread and hence the infections are correlated. This survey presents an overview of recen...
