Your Work Environment
Light–matter interaction at the single-quantum level is the cornerstone of quantum information science and technology. However, single quanta generally interact only weakly, and enhancing this coupling has been a major driving force for a large research community. Integrated photonic nanostructures offer a promising route to engineering light–matter interactions by tailoring the emitter's electromagnetic environment. Indeed, modern nanofabrication techniques have enabled the realization of solid-state systems with embedded emitters, such as quantum dots integrated into photonic crystal waveguides or high-quality-factor nanocavities, giving rise to the field of quantum nanophotonics.
In this context, we explore the paradigm of waveguide quantum electrodynamics by trapping atoms in the vicinity of photonic crystal waveguides supporting slow-light modes. This enables strong atom–photon coupling without the need for a cavity, collective responses in mesoscopic atomic ensembles, and strong atom–atom interactions mediated by the slow-light mode. This approach opens new possibilities for quantum information networks, ranging from single-photon transistors and photonic quantum gates to quantum simulation protocols.
