New AC-Powered SFQ Digital Circuits
New AC-Powered SFQ Digital Circuits
Recent progress of Reciprocal Quantum Logic (RQL) has renewed interest in AC powering of superconductor digital circuits, which had been abandoned since the famous IBM project of 1970s. In this work we propose and demonstrate new AC-biased Single Flux Quantum (SFQ) circuits, and search for synergy of AC and currently …
