摘要：

A quantum flux parametron (QFP) is a single quantum flux superconductive device that has a potential of up to 100 GHz switching with nW-order power dissipation. These features make QFP's very promising for realizing ultra-high speed computers. This paper describes the potential of the QFP and key technologies when QFP's are applied to a Josephson supercomputer. First, switching speed, stability, and power dissipation of a QFP are discussed. QFP gates, circuits, and systems are next described. Then, ultra-fast clock distribution using a standing wave are explained. High-speed operation at more than 10 GHz and 10(14) error-free operations per QFP have been demonstrated. Finally described is a high-density packaging scheme by three-dimensional integration, which is very important for ultra-high speed circuits because the propagation delay becomes dominant in such circuits.
