This article reviews belief propagation (BP) for classical inference problems and describes its extension to quantum systems, which is known as BP with quantum messages (BPQM). Since BP plays a key role in many low-complexity decoders for error-correcting codes, BPQM enables the practical extension of these decoders to classical quantum channels, such as the...
In this article, we present our vision for how extremely large aperture arrays, equipped with hundreds or thousands of antennas, can play a major role in future 6G networks by enabling a remarkable increase in data rates through spatial multiplexing of a massive number of data streams to both a single user and many simultaneous users. Specifically, with the ...
The mission of our society is to support the open exchange of ideas in information theory. I am excited to write this inaugural President’s column for the Â鶹´«Ã½Ó³» Information Theory Society’s new BITS magazine. The concept of a magazine has been discussed in our society for many years, going back at least to 2015. It took the intense effort of [...]
The papers in this special issue focus on information processing in the arts and humanities. Recent years have witnessed the emergence of various sophisticated information processing tools — including some involving artificial intelligence — that are capable of interrogating increasingly complex datasets in order to tackle challenges arising in a wide range ...
Machine learning (ML), being now widely accessible to the research community at large, has fostered a proliferation of new and striking applications of these emergent mathematical techniques across a wide range of disciplines. In this article, we will focus on a particular case study: the field of paleoanthropology, which seeks to understand the evolution of...
