Quantum Codesign

Codesign has been an integral part of computer architecture since the very first systems were brought online. From the early days of the field until now, end-user applications inevitably shape the design and capabilities of subsequent generations of hardware. Likewise, the characteristics and capabilities of new computational hardware and systems often impact the algorithms and software that run on them. Quantum computing (QC) is similarly reliant on codesign approaches, particularly now in its resource constrained early days. This article discusses what codesign means in a QC setting, gives examples of its value to QC, and proposes key attributes of QC codesign approaches going forward.
