The quantum defects in nanodiamonds, such as nitrogen-vacancy (NV) centers, are emerging as promising candidates for nanoscale sensing and imaging, and the controlled placement with respect to target locations is vital to their practical applications. Researchers in Hong Kong have developed on-demand electrohydrodynamic printing of nanodiamonds containing NV centers with high precision control over quantity and position. After thorough characterizations of the printing conditions, they showed that the number of printed nanodiamonds can be controlled at will, attaining the single-particle level precision. This printing approach enables positioning NV center arrays with a controlled number directly on the universal substrate without any lithographic process. The approach is expected to pave the way toward new horizons not only for experimental quantum physics but also for the practical implementation of such quantum systems…read more.
