With the advent of the second quantum revolution, striving for real-world applications of quantum technologies, enormous efforts have been made to develop and optimize the necessary building blocks. For photonic quantum technologies, which uses single light particles – photons – as quantum information carriers (qubits), one crucial technology is the quantum light source, generating these qubits. In my lecture, I will highlight the major applications of photonic quantum technologies and discuss the requirements set on the quantum light sources. However, no ideal quantum light source has yet been developed, addressing all prerequisites at once. In recent years, epitaxial semiconductor quantum dots have achieved substantial progress, bringing us closer to practical sources for real-life applications. I will discuss our efforts improving source properties such as purity, brightness, indistinguishability, and on-demand entangled photon pair generation with respect to the requirements in quantum communication.
