Abstract
Nitrogen-vacancy centers in diamond have been long used for spin-based optical sensing and considered viable candidates for implementing spin-based quantum information protocols. Their unique advantages include their nanoscale size and the optical readout of the electron spin state. These features make them particularly fit for the use in integrated nanophotonic and quantum optical devices. We will discuss how the optical Purcell effect in plasmonic systems affects the NV spin readout signal and present the demonstration of this readout through optical plasmons in an integrated nanophotonic interface. We will show that spin relaxometry is a powerful tool that allows to probe the magnonic density of states and its electrical tuning with sub-um spatial resolution. Furthermore, we will discuss how spin signal readout sensitivity can be enhanced with the use of plasmonic nanostructures and Bayesian measurement methods.
