摘要： One embodiment includes a clock distribution system. The system includes a first resonator spine that propagates a first clock signal and a second resonator spine that propagates a second clock signal that is out-of-phase relative to the first clock signal. The system also includes at least one resonator rib each conductively coupled to at least one of the first and second resonator spines and being arranged as a standing wave resonator with respect to a respective at least one of the first and second clock signals to inductively provide the respective at least one of the first and second clock signals to an associated circuit via a respective transformer-coupling line. The system further includes an isolation element configured to mitigate at least one of inductive and capacitive coupling between the first and second clock signals.

摘要： A superconducting on-chip coiled coupled-line 90° hybrid coupler is made of a series array of repeated cells of coiled transmission lines that are inductively and capacitively coupled. The coupler splits an incoming microwave signal into two output signals of roughly equal power and separated in phase from each other by roughly 90°. The coupler can be incorporated into such superconducting electronic circuits as clock-distribution networks for reciprocal quantum logic (RQL) systems, as well as Josephson-based phase shifters and vector modulators.
