Random multiple-scattering has become an exciting platform for classical and quantum optical experiments [1-5]. In wavefront shaping one uses spatial light modulation in combination with strongly scattering materials to achieve control over light in space and time . Recent wavefront-shaping experiments have transformed opaque media in equivalents of many optical components that are inherently robust against disorder and imaging errors for classical light. We demonstrate an algorithm that allows programming any linear optical circuit in multiple-scattering media with phase-modulation of the incident wavefront. We want to apply this method on wavefront shaping of quantum light to obtain ample flexibility in optimization and manipulation of the quantum interference, which we call adaptive quantum optics . This offers unique opportunities for sample characterization, quantum patterning, secure key generation, or studying quantum transport through disordered media.
