Creation of an optically-generated-flux-quantum nano-device with superconducting nanobridges
Research Site Assistant Professor, Institute of Laser Engineering, Osaka University | |
The technologies of a single-flux-quantum (SFQ) logic circuit with a high Tc superconductor (HTS), which can operates in terahertz frequency region in principle, is an attractive candidate for the alternative technology to CMOS devices. However, the HTS-SFQ circuit is facing serious difficulties concerning integration processes and an interface between peripheral systems and the SFQ circuits. To overcome these difficulties, I propose a novel SFQ device "optically-generated-flux-quantum nano-device" in which superconducting nanobridges and optically generated flux quanta are introduced by combining nanotechnologies and terahertz technologies.
