Abstract: Photonics offers a promising approach to study quantum physics and realize quantum technology. Integrated photonic devices can pack many optical components into a small form-factor, enabling complex optical circuits that process light on-a-chip. But photons lack nonlinear interactions required to engineer entanglement and apply quantum gates. In this talk, I will describe our work toward engineering strong photonic interactions using nanophotonics. I will show how semiconductor quantum dots can mediate strong photon-photon interactions, and how we can exploit these interactions to implement fundamental quantum operations. I will then discuss how the combination of quantum photonics with synthetic dimensions could enable large scaling and deterministically tailor highly entangled multi-photon states. Finally, I will describe our experimental effort towards implementing synthetic dimensions in a real device to realize a strongly interacting random walk of photons, an important primitive for quantum simulation and quantum information processing.
