Coherent Microwave Control of a Nuclear Spin Ensemble at Room Temperature

P. Huillery,
J. Leibold,
T. Delord
et al.

Abstract: We use nominally forbidden electron-nuclear spin transitions in nitrogen-vacancy (NV) centers in diamond to demonstrate coherent manipulation of a nuclear spin ensemble using microwave fields at room temperature. We show that employing an off-axis magnetic field with a modest amplitude (≈ 0.01 T) at an angle with respect to the NV natural quantization axes is enough to tilt the direction of the electronic spins, and enable efficient spin exchange with the nitrogen nuclei of the NV center. We could then demonst… Show more

“…Several solutions are envisioned to increase the trapping frequency and/or reduce the spin linewidth. One of them consist in coupling the NV electronic spins to the nuclear spins of the nitrogen atoms [96] or to employ distant coupling schemes between NV centers in ultra-pure diamonds and strongly confined ferromagnetic particles [69]. We discuss diamond fabrication issues in the part VII A.…”
