Original Abstract Submitted

a method of constructing a superconducting switch includes providing a substrate. a first superconducting metal line is fabricated on the substrate, wherein the superconducting metal line has a left portion, a right portion, and a center portion patterned along a first crystalline direction of the substrate. one or more etch release holes are provided in the center portion of the first superconducting metal line. the center portion of the superconducting metal line is released from the substrate with an anisotropic etch through the etch release holes in a manner that reduces the undercut distance elsewhere on the substrate
