Abstract
One embodiment of the invention includes a switch circuit including a first superconducting transmission line, a second superconducting transmission line and a phase-change material switch that is coupled between the first and second superconducting transmission lines. The phase-change material switch includes a switch portion that includes a phase-change material that is superconducting in a first state of the switch portion and blocking in a second state of the switch portion, such that the phase change material switch is configured to propagate an input signal from the first superconducting transmission line to the second superconducting transmission line in the first state, and to prohibit propagation of the input signal from the first superconducting transmission line to the second superconducting transmission line in the second state.
