The resistance induced by nanosecond pulses of electric currrent or of light has been studied in superconducting Nb and NbN thin films. Narrow bridges exhibit the features expected from quasi-1D transport, namely, localized phase-slip centers (PSC) a

The Rapid Single-Flux-Quantum logic (RSFQ) presents an efficient way to achieve ultra fast digital operations. This logic uses the macroscopic effects which can be found in nano-structured superconductor devices such as the Josephson AC and DC effect
