Abstract

Semiconductors have dominated every aspect of electronics over the past decades. However, the diminishing gains in performance and power efficiency observed in recent years, coupled with the diversification of target applications, have sparked a search for the next breakthrough. Although it is unlikely for semiconductors to be completely replaced in the foreseeable future, there are signs that a transition to superconductors may benefit many domains from classical high-performance computing and quantum computing to sensing systems. In this work, I firstly introduce the underlying principles of superconductor electronics and describe how common misconceptions have hampered progress. Secondly, I present a logic-biasing co-optimization that results in a versatile superconducting logic family with truly zero static power dissipation. Thirdly, I describe how to overcome the biggest obstacle in superconducting computing—the lack of a scalable memory solution—by exploiting nearly-lossless passive superconducting delay lines. Finally, I outline a roadmap for practical superconducting computing and discuss how this can be generalized to close the gap between other emerging devices and applications.
