Author(s): I. M. Morris, T. Lühmann, K. Klink, L. Crooks, D. Hardeman, D. J. Twitchen, S. Pezzagna, J. Meijer, S. S. Nicley, and J. N. Becker The negatively charged nickel vacancy center (${\mathrm{NiV}}^{−}$) in diamond is a promising spin qubit candidate with predicted inversion symmetry, large ground state spin-orbit splitting to limit phonon-induced decoherence, and emission in the near infrared. Here, we experimentally confirm the pr… [Phys. Rev. Lett. 135, 043602] Published Wed Jul 23, 2025
