Abstract
A device comprises a switch circuit and control lines. The switch circuit comprises a plurality of signal input/output ports, and a plurality of switch nodes, each switch node comprising a superconducting loop which comprises a plurality of Josephson junctions arranged in a ring configuration. The control lines are configured to selectively apply flux bias control signals to the switch nodes. The plurality of switch nodes is arranged to selectively configure a signal routing path between any pairwise combination of signal input/output ports of the plurality of signal input/output ports, in response to flux bias control signals selectively applied to the switch nodes.
