Widely tunable on-chip microwave circulator for superconducting quantum circuits
Benjamin J. Chapman, Eric I. Rosenthal, Joseph Kerckhoff +6
We report on the design and performance of an on-chip microwave circulator with a widely (GHz) tunable operation frequency. Non-reciprocity is created with a combination of frequen…

Single-sideband modulator for frequency domain multiplexing of superconducting qubit readout
Benjamin J. Chapman, Eric I. Rosenthal, Joseph Kerckhoff +3
We introduce and experimentally characterize a superconducting single-sideband modulator compatible with cryogenic microwave circuits, and propose its use for frequency domain mult…
