Demonstration Of A Superconducting Nanowire Microwave Switch

The functionality of a nanowire integrated into a superconducting transmission line acting as a single pole single throw switch is demonstrated. The switch has an instantaneous bandwidth from 2 to 8 GHz with more than 10 dB of isolation between the open and closed states. The switch consumes no power in the closed state and approximate to 15 nW in the open state. The rise and fall response time between open and closed states is approximately 370 ps.
