The success of CMOS has overshadowed nearly all other solid-state device innovations over recent decades. With fundamental CMOS scaling limits close in sight, time is now ripe for an expedition to explore emerging disruptive computing technologies. The DISCoVER Expedition will explore novel superconductor electronics as a viable post-CMOS computing technology. Superconductor electronics can deliver ultra-high performance and energy efficiency at scale. The potential transition to superconductor electronics will be revolutionary, analogous to the transition of NMOS-only logic to CMOS logic in the 1970s. While energy efficiency was the initial driver for the transition to CMOS, the benefits of CMOS went far beyond energy-efficiency gains and included ultra-scale integration and more reliable circuits. In a similar vein, this DISCoVER Expedition will pave the way for seminal innovations in integrated electronics, sustainable exa-scale computing, and acceleration of machine learning. DISCoVER will enable computing paradigms that can facilitate modeling of climate-change effects, detection of underground geological resources, enhancement of pharmaceutical drug design for personalized medicines and healthcare, and development of innovative smart materials and infrastructure. DISCoVER will help ensure the preeminence of the US as a technological world leader and guide future hardware and chip-manufacturing investments.The DISCoVER team will design and demonstrate a superconductive system of cryogenic computing cores (SuperSoCC), an artifact built from superconductive electronic components capable of yielding 100x improved energy efficiency at the same performance as CMOS. The system demonstration pursuit is enabled by the team’s innovations in superconducting materials and devices, circuits and architectures that scale, advanced design-automation tools for easing design complexity, and supporting compilers and runtime systems. Through this multi-faceted program, the DISCoVER Expedition will methodically lower the technology-transfer barriers related to physical scaling, integration complexity, tool support, and interfacing to room-temperature electronics. Through its curriculum innovations, DISCoVER will empower a new generation of engineers and entrepreneurs who will bring superconducting to the mainstream of computing. The hands-on superconducting labs housed at USC, combined with K-12 outreach across partner institutions, will allow the DISCoVER team to bring the excitement of computing hardware to future generations of the workforce. With innovative collaboration with USC’s I-Corp and industry affiliates, DISCoVER is poised to open the power of superconducting technology for tackling critical societal challenges. The DISCoVER Expedition is led by the University of Southern California and includes faculty and researchers from Auburn, Cornell, Northeastern, Northwestern, Rochester, and Yokohama National University (as an international academic partner).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

近几十年来，CMOS的成功几乎盖过了所有其他固态器件的创新。随着基本的CMOS缩放限制越来越近，探索新兴颠覆性计算技术的时机已经成熟。 DISCOVER Expedition将探索新的超导电子学作为可行的后CMOS计算技术。超导电子可以大规模提供超高性能和能效。向超导体电子学的潜在过渡将是革命性的，类似于20世纪70年代纯NMOS逻辑向CMOS逻辑的过渡。虽然能源效率是向CMOS过渡的最初驱动力，但CMOS的好处远远超出了能源效率的提高，还包括超大规模集成和更可靠的电路。同样，DISCOVER Expedition将为集成电子、可持续的exa级计算和加速机器学习方面的开创性创新铺平道路。 DISCOVER将使计算范例能够促进气候变化影响的建模，地下地质资源的检测，个性化药物和医疗保健的药物设计的增强，以及创新智能材料和基础设施的开发。DISCoVER将帮助确保美国作为世界技术领导者的卓越地位，并指导未来的硬件和芯片制造投资。DISCoVER团队将设计和演示一个由低温计算核心（SuperSoCC）组成的MEMS系统，这是一个由MEMS电子元件构建的工件，能够在与CMOS相同的性能下将能效提高100倍。该团队在超导材料和器件、电路和可扩展架构方面的创新、用于简化设计复杂性的先进设计自动化工具以及支持编译器和运行时系统，使系统演示工作得以实现。 通过这一多方面的计划，DISCoVER Expedition将系统地降低与物理缩放、集成复杂性、工具支持以及与室温电子设备接口相关的技术转移障碍。通过课程创新，DISCoVER将赋予新一代工程师和企业家权力，他们将把超导技术带入计算的主流。位于南加州大学的超导实验室，结合合作机构的K-12推广，将使DISCoVER团队能够将计算硬件的兴奋带给未来的劳动力。通过与USC的I-Corp和行业附属公司的创新合作，DISCoVER准备开启超导技术的力量，以应对关键的社会挑战。DISCOVER Expedition由南加州大学领导，包括来自奥本、康奈尔、东北大学、西北大学、罗切斯特和横滨国立大学（作为国际学术合作伙伴）的教师和研究人员。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
