Abstract

Adiabatic quantum-flux-parametron (AQFP) logic, known as a parametron-based digital logic using superconducting Josephson junctions, can offer extremely high energy efficiency for building high-performance computing systems. With resistance-less wires, ultrafast switches, and nearly zero operational energy loss, these superconducting logic circuits can operate at clock frequencies from 5 GHz to 10 GHz. 

In this talk, we will provide an overview of the AQFP technology, in terms of the fundamental principle, some physical demonstrations and a framework of the top-down design flow.
