Abstract
A superconducting circuit includes a first port and a plurality of second ports; a plurality of filter poles, each filter pole comprising an inductor and a capacitor connected in parallel, between the first port and a second port in the plurality of second ports; an admittance inverter comprising at least one of a coupling capacitor, a coupling inductor, and a Josephson junction, the admittance inverter linking two successive filter poles together. The plurality of filter poles and associated admittance inverters define a plurality of current branches so that, when operating as a demultiplexer, an input electrical current input though the first port is routed to a selected one of the plurality of the plurality of second ports by an application of a first set of magnetic flux biases.
