Abstract – The International Roadmap for Devices and Systems (IRDS) recently succeeded the International Technology Roadmap for Semiconductors (ITRS). The roadmap driver changed from scalin physica dimensions to application requirements and now includes a broader range of non-semiconductor technologies, such as superconductor electronics (SCE). In 2018 the IRDS published its 2017 roadmap reports and elevated Cryogenic Electronics and Quantum Information Processing (CE&QIP) to the status of an international focus team (IFT). Superconductor electronics is a key area, both on its own and within QIP. For the 2018 report, we consider initial application areas and market drivers for superconductor electronics using the IRDS framework. Applications such as computational accelerators will require significant improvements in circuit density, complexity, functional capability, memory capacity, and data rates in and out of the cryogenic environment. Models, metrics, and benchmarks predict device and system performance and guide technology roadmapping to meet application requirements. A process for developing an application-driven roadmap for superconductor electronics is described and a first roadmap is proposed.
