optical tweezers quantum physics simulation nitrogen vacancy center experimental design
Abstract:
Owing to its unique band structure, the nitrogen vacancy (NV) center in diamonds provides a novel, highly sensitive quantum system for detecting magnetic fields. Deterministically arranged ensembles of NV centers can provide enhanced magnetic field detection capabilities, but can be challenging to arrange. This thesis proposes a new method for engineering arrays of NV centers by utilizing optical tweezers for placement of single nanodiamonds that contain NV centers. Controlled movement of nanoparticles using an optical tweezers set up is demonstrated through an experimental apparatus developed for this thesis. Through a simulated optical trap, it is found that nanodiamonds may be maneuvered with this optical trap setup over a wide range of laser power and nanodiamond radii ranges. Further, this thesis examines positioning accuracy in a simulated optical trap, finding that laser power is the most critical factor in ensuring accurate placement of nanodiamonds onto a sample.
