Exploiting the quantum properties of the light has the potential of enabling many new applications in the field of photonics and quantum information technology, such as secure communication, imaging and lithography techniques beyond the diffraction limit, quantum repeaters as well as photonic quantum computing. Many of these applications require the generation of on demand indistinguishable single photons or entangled photon pairs. Resonantly excited single semiconductor quantum dots are perfectly suited to fulfill these requirements.

In my talk, I will discuss the fascinating physic as well as the current status of such resonantly driven semiconductor light sources for the generation of single-photons, entangled photons and so called NOON states, which are maximally path entangled multi-photon states. Finally, I will report on single-photon on-chip experiments on an InGaAs/GaAs/AlGaAs semiconductor platform.
