Decoding algorithms are essential to fault-tolerant quantum-computing architectures. In this perspective we explore decoding algorithms for the surface code; a prototypical quantum low-density parity-check code that underlies many of the leading efforts to demonstrate scalable quantum computing. Central to our discussion is the minimum-weight perfect-matchin...
This article puts the spotlight on the receiver front-end (RFE), an integral part of any wireless device that information theory typically idealizes into a mere addition of noise. While this idealization was sound in the past, as operating frequencies, bandwidths, and antenna counts rise, a soaring amount of power is required for the RFE to behave accordingl...
Channel coding is one of the workhorses of the physical layer, enabling reliable and energy-efficient data transmission. In this article, we highlight the core innovations in channel coding that have been commercialized in wireless mobile communication standards over the past decades, in the context of current and anticipated future requirements. We point ou...
