Nonclassical properties of light, such as squeezing and entanglement, generated in nonlinear optical processes, serve as resources for quantum technologies. Novel sources of light with such properties are being explored within NOA creating a need for efficient techniques to characterize and tailor the generated quantum states. We develop and optimize such techniques, targeting hybrid sources combining parametric down conversion with few-level emitters and light from high-harmonic generation processes. We account for limited measurement capabilities and noise, and use experimentally available state-engineering techniques. Moreover, we advance existing techniques on the conceptional level potentially impacting continuous-variable quantum information processing more broadly.
