Abstract

Optical illumination of the N-V color center in diamond gives selective population of the ground electron spin levels and by working close to an avoided crossing polarization of the nuclear hyperfine levels is also obtained.

Quantum control of single spins and photons in diamond

Yiwen Chu, Emre Togan, Mikhail D. Lukin

The nitrogen-vacancy (NV) color center in diamond shows great promise as an optically addressable solid-state qubit amenable to many quantum-optics applications. Using the NV center, we have demonstrated spin-photon entanglement and manipulation of nuclear spins through coherent population trapping.

Microwave-Free $^{13}$C Hyperpolarization of Diamond Particles Enabled by Magic Angle Spinning and NV Centers

Rémi Blinder, Guzel Musabirova, Daehee Kim +6 more

Nuclear hyperpolarization from optically pumped color centers in solids offers an alternative to conventional microwave-driven dynamic nuclear polarization (DNP). Diamond can host the nitrogen vacancy (NV) center, whose ground spin state can be readily polarized by light at room temperature, making diamond a candidate platform for nuclear hyperpolarization. We report $^{13}{\rm C}$ nuclear hyperpolarization in randomly oriented diamond particles with sizes ranging from 0.2 to 2 $μ$m, both at natural $^{13}{\rm C}$ abundance (1.1 %) and at 20 % isotopic enrichment, at magnetic fields of 7.1 T and 9.4 T. The protocol combines optical illumination with magic angle spinning (MAS) and does not require microwave irradiation. By investigating the nuclear polarization as a function of the MAS frequency between 0 and 6 kHz at the magnetic field of 7.1 T, we find maximum light-induced polarization enhancements of $280$-fold for the isotopically enriched sample and $411$-fold for the natural abundance sample. Under continuous illumination, steady-state absolute $^{13}{\rm C}$ polarization levels above 0.1 % are reached. A model involving optical pumping of NV centers and spin dynamics near level anticrossings (LACs) in three-spin clusters formed by NV, a substitutional nitrogen (P1) and $^{13}{\rm C}$ is used to describe these findings. The protocol strongly mitigates the effect of the anisotropy of the NV spin Hamiltonian, allowing more than $99.9\%$ of NV orientations to participate in the polarization transfer process. These results represent a first step toward transferring nuclear polarization from diamond particles to external nuclei, with potential applications in sensitive and high-resolution NMR at room temperature.

Nitrogen-vacancy center in diamond: Model of the electronic structure and associated dynamics

Neil B. Manson, J. P. Harrison, Matthew J. Sellars

Symmetry considerations are used in presenting a model of the electronic structure and the associated dynamics of the nitrogen-vacancy center in diamond. The model accounts for the occurrence of optically induced spin polarization, for the change of emission level with spin polarization and for new experimental measurements of transient emission. The rate constants given are in variance to those reported previously.

Room-temperature optical polarization of nuclear ensembles in diamond

Ran Fischer, Andrey Jarmola, Pauli Kehayias +1 more

We report polarization of a dense nuclear-spin ensemble in diamond at room temperature. The method is based on the transfer of electron spin polarization of negatively charged nitrogen vacancy (NV) color centers to the nuclear spins via the excited-state level anti-crossing (ESLAC) of the center. We demonstrate polarization of 80% of the 14 N nuclear spins related to the NV centers, as well as that of 50% of the proximal 13 C nuclear spins. This work may enable polarization of the 13 C in bulk diamond, which is of interest to applications of nuclear magnetic resonance, quantum memories in hybrid quantum devices, and in sensing.
