Abstract
A technique relates to configuring a superconducting router. The superconducting router is operated in a first mode. Ports are configured to be in reflection in the first mode in order to reflect a signal. The superconducting router is operated in a second mode. A given pair of the ports is connected together and in transmission in the second mode, such that the signal is permitted to pass between the given pair of the ports.
Claims4
A superconducting router comprising:
- ports configured to selectively operate in a first mode and a second mode, wherein in the first mode the ports are configured to be in reflection in order to reflect a signal, tunable filters being associated with the ports;
- and
- a given pair of the ports configured to operate in the second mode, wherein in the second mode the given pair of the ports is coupled together and in transmission, such that the signal is permitted to communicate between the given pair of the ports, each of the given pair of the ports in the second mode respectively having one of the tunable filters in transmission, the one of the tunable filters comprising a unit cell void of a hybrid coupler.
