High fidelity readout of a transmon qubit using a superconducting low-inductance undulatory galvanometer microwave amplifier

We report high-fidelity, quantum non-demolition, single-shot readout of a superconducting transmon qubit using a dc-biased superconducting low-inductance undulatory galvanometer (SLUG) amplifier. The SLUG improves the system signal-to-noise ratio by $6.5\;{\rm dB}$ in a $20\;{\rm MHz}$ window compar...
