Superconducting Single-Flux-Quantum (SFQ) circuits utilise the quantised magnetic flux, a fundamental physical constant, to represent and process digital information. By harnessing the unique ...
There is plenty of experimental evidence on magnetic flux quantization from superconducting loops to two-dimensional electron ...
Image is a microphotograph of the fabricated test circuit. Continuous single flux quantum signals are produced by the clock generators at frequencies ranging from approximately 10 GHz to 40 GHz. Each ...
