Photonic quantum technologies rely on the ability to generate, process, and detect quantum states of light. Engineering the best possible building blocks for theses task does not only require high purity materials and advanced nanofabrication but moreover to develop an in-depth understanding of the underlying physical processes. In this talk, I will provide insights into the dynamics of generating non-classical light from optically active few-level quantum systems, represented by semiconductor quantum dots [1-4]. Moreover, our recent progress in pushing the limits of superconducting nanowire single photon detectors via local He-ion irradiation will be discussed [5-7].
