In this episode, we explore the future of superconductor electronics—a promising post-CMOS computing paradigm offering ultra-low energy consumption and ultra-high processing speeds. Dr. Sasan Razmkhah of USC’s SPORT Lab joins the conversation to discuss cutting-edge research aimed at making superconductor very-large-scale integration (sVLSI) a practical reality.

We dive into the development of Fast-Phase Logic (FPL), a next-generation logic family that uses π-Josephson junctions and stacked zero-Josephson junctions to dramatically increase logic density while reducing power requirements. The discussion also covers hybrid system architectures that integrate superconductor logic with CMOS, spanning multiple temperature zones to balance performance, efficiency, and manufacturability.

Together, these advances outline a roadmap toward scalable, energy-efficient computing systems—pointing to a future where superconductors play a central role in high-performance and AI-driven computing.

This deep-dive episode explores the ideas from Jeff Shainline’s recent seminar on superconducting optoelectronic networks (SOENs) and the radical rethink of AI hardware they represent. We unpack how SOENs combine analog superconducting circuits, integrated memory, and single-photon optical communication to bypass the von Neumann bottleneck and deliver massive gains in speed, energy efficiency, and scalability. If you’re curious about brain-inspired hardware, trillion-parameter AI, or the future of computation, this episode guides you through the key concepts and why they matter.

In this episode, we recap highlights from a seminar by Dr. Sam Benz of the NIST Superconductive Electronics Group, exploring his team’s cutting-edge work in quantum-based signal synthesis and precision measurement systems.

Dr. Benz’s research focuses on superconducting voltage sources, quantum reference systems, and ultra-precise tools used by advanced laboratories and industries around the world. We break down key takeaways from his talk, including developments in high-speed computing, quantum technologies, and RF communications — all made possible by superconductive electronics.

Whether you're new to the topic or looking to better understand where quantum technology is headed, this seminar recap makes the science both clear and compelling.
