ABSTRACT:
A superconducting device may include a superconducting weak link equipped with plural superconducting devices that are used as input-output terminals formed on the same plane and at least one current source for applying current to at least one of these superconducting electrodes. A superconducting device suitable for high integration can be realized as it enables structuring of a superconducting weak link 1 equipped with plural superconducting electrodes 101, 102, 103 and 104 that can be used as input-output terminals and changing symmetry of superconducting electrode arrangement through the form of a normal conductor 201 which is forming a superconducting weak link. In addition, when this superconducting device is used as a quasi-particle injection type device, a superconducting device with plural superconducting electrodes that can be used for a gate electrode, drain electrode or control electrode can be realized. Further, a superconducting device equipped with new functions (e.g. motion as a neuron device) which are capable of high integration can be realized by utilizing these characteristics. Furthermore, being a proximity effect type, superconducting weak link has an advantage of realizing an ultra highspeed, low electricity consuming switching device.
