Abstract
A cryogenic analog switch circuit includes a magnetic strip and a superconductor strip. The magnetic strip generates a first and second magnetic domain separated by a domain wall. In response to a current through the magnetic strip, the domain wall moves to change respective extents of the first and second magnetic domains within the magnetic strip. The superconductor strip is disposed adjacent the magnetic strip for undergoing a phase transition switching between a superconducting state and a normal state in response to a magnetic field controlled by the respective extents of the first and second magnetic domains within the magnetic strip.
