What is it about?
Finding the right material platform for interfaces to solid state emitters has been a long-standing bottleneck for scaling up solid state quantum systems. In this work, we demonstrate that nitrogen rich silicon nitride is a viable platform by showing that nitrogen vacancy centers embedded in nanodiamonds preserve both their quantum optical and spin properties when encapsulated in the film.

Why is it important?
This work moves away from finding the right type of atom-like system to an approach with the focus on integrating many atom-like emitters in a chip-scale technology
