Abstract

Trapping of a nanodiamond/microdiamond containing Nitrogen-Vacancy centers in the vacuum is an ideal platform to develop a hybrid mechanical system. In such a system, the coupling between the Nitrogen-Vacancy centers and the mechanical motion of a trapped diamond provides pathways for generating a quantum superposition state of the mechanical motion with long coherence time. In this work, I demonstrate our preliminary data in the detection of Nitrogen-Vacancy spin signals from trapped diamonds using optical and magneto-gravitational trapping technologies. I compared the advantages and drawbacks of both techniques and improvements need to be made. I also explored the charge dynamics of Nitrogen-Vacancy centers in diamonds under near-IR laser illumination and first demonstrate low energy (0.95 to 1.18 eV or 1050 to 1300 nm) Multi-photon Photoluminescence Excitation (PLE) spectrum of NV centers in a sub-millimeter diamond crystal.
