Conventional digital computing faces fundamental physical limits: large scale computing systems already consume tens of Megawatts of power, Dennard scaling has ended, and data movement costs dominate application performance. Next generation experimental facilities generate data at rates that overwhelm conventional processing and demand real-time analysis at the source. Analog computing, which exploits the continuous dynamics of physical systems to perform computation, promises a transformative path toward orders-of-magnitude gains in energy efficiency and time-to-solution for scientific workloads.

The workshop’s findings also identified several cross-cutting challenges underpinning all six PRDs, including a mathematical theory of continuous computation under noise, programming abstractions and compiler toolchains, and community benchmarking infrastructure, emphasizing the needs for a coordinated, multi-faceted effort to enable rapid progress in the area. The research directions outlined in the workshop report aim to guide the development of energy-efficient analog computing technologies that can support future scientific discoveries and address the growing energy demands of scientific computing and artificial intelligence.

In July 2023, DOE’s Advanced Scientific Computing Research (ASCR) program in the Office of Science (SC)convened the Workshop on Basic Research Needs in Quantum Computing and Networking, where major opportunities and challenges were discussed and identified. Before the workshop, a pre-workshop report was prepared to seed potential research themes, and community input was solicited in the form of brief position papers. These formed the basis of panel and discussion sessions at the workshop. This report summarizes the findings of the workshop.
