Nano meets Quantum – Nanophotonics for new regimes in quantum optical precision experiments

Optical metamaterials provide a fascinating platform to tailor light fields in virtually arbitrary manner. Particularly in the field of high-precision optical metrology and quantum technology, metasurfaces and waveguide structures give promise to overcome the limitations of conventional bulk optics. These photonics systems allow the integration of even complex optical functionalities into compact and robust devices enabling scalable systems e.g. for chip-based quantum computing. On the other hand, the spatial control of optical near fields by metamaterials enables the control of light-matter interaction. This capability is particularly important for optical atomic clocks which belong to the most precise experiments ever developed by mankind. In this contribution, we give an overview on the development and possibilities of Nanophotonic devices for applications in precision optical experiments. We explain important physical phenomena of light-matter interaction and illustrate the role of material properties in these experiments.
