High current gain Josephson junction circuit
Patent
·
OSTI ID:5580355
A superconductive circuit is described for diverting bias current to an output line in response to magnetic field control means. A first plurality of branches containing magnetically switchable Josephson junction gates are connected in parallel, and a second plurality of the same gates, less than or equal in number to the first plurality, are actuated essentially simultaneously by the control means. As a consequence, high-gain, high-speed operation is made possible.
