    • Side locking was used in this instance to demonstrate the ease of locking the QC laser with a simple technique. Pound-Drever-Hall modulation was also used, yielding similar results but over less bandwidth owing to some extra time delays. Frequency-modulated saturated absorption locking experiments are clearly the next stage for QC stabilization.

    • note
    • Unlike the control-reference signal subtraction, the witness signal was measured directly. It was found unnecessary to subtract the reference signal here, as the impact of the amplitude noise was found to be negligible compared with the detector-preamplifier noise floor, as can be seen from Fig. 3.
