The mechanical and thermal properties of the nitrogen-vacancy centre in diamond [article]

Michael Samuel James Barson, University, The Australian National, University, The Australian National
2018
In the past decade or so, the nitrogen-vacancy (NV) centre in diamond has proven itself to be a remarkably powerful tool for nanoscale quantum sensing and quantum information processing in ambient conditions  ...  This can limit the practical use of such quantum devices. A quantum tool that can successfully and simply operate in ambient conditions would provide major advances in quantum technology.  ...  ) and amplier (Mini-Circuits).  ...
