Abstract
The coherent control of the orbital state is crucial for realizing the extremely-low power manipulation of the color centers in diamonds. Herein, a neutrally-charged nitrogen-vacancy center, NV<sup>0</sup>, is proposed as an ideal system for orbital control using electric fields. The electric susceptibility in the ground state of NV<sup>0</sup> is estimated, and found to be comparable to that in the excited state of NV<sup>-</sup>. Also, the coherent control of the orbital states of NV<sup>0</sup> is demonstrated. The required power for orbital control is three orders of magnitude smaller than that for spin control, highlighting the potential for interfacing a superconducting qubit operated in a dilution refrigerator.
