By embedding quantum emitters, such as quantum dots, within nanophotonic structures we have gained unprecendented control over their properties and over the photons with which they interact. Yet this control comes at a price, namely the unwanted interaction of the emitters with the noisy solid-state environment of the photonic circuits. In this talk, I will address different ways in which we attempt to address this challenge, focusing on the resultant increased coherence of quantum light-matter interactions. I will show how these improvements allow us to route photons on integrated chips and begin to use nonlinear scattering events to reshape photon wavefunctions. In this discussion, the way that these capabilities may lead to novel quantum technologies will be highlighted.
