We develop a systematic approach to the realisation of active quantum filters directly from their frequency-domain transfer functions, utilising a set of techniques developed by the quantum control community. This opens the path to the development of new types of active quantum filters for high-precision measurements. As an illustration, the approach is applied to realise an all-optical unstable filter with broadband anomalous dispersion, proposed for enhancing the quantum-limited sensitivity of laser interferometric gravitational-wave detectors.
