From: Beating the Ramsey limit on sensing with deterministic qubit control
All qubit control envelopes are generated by the Zurich Instruments HDAWG, then upconverted and combined with measurement pulses from the ZI UHFQA before being fed into a heavily attenuated line. Readout signals are amplified and then downconverted and fed back into the UHFQA for analysis.
