Abstract

The coherent control of the orbital state is crucial for color centers in diamonds for realizing extremely low-power manipulation. Here, we propose the neutrally charged nitrogen-vacancy center, NV⁰, as an ideal system for orbital control through electric fields. We estimate electric susceptibility in the ground state of NV⁰ to be comparable to that in the excited state of NV^-. Also, we demonstrate coherent control of the orbital states of NV⁰. 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.
