Webb11 maj 2024 · High-fidelity quantum operation of qubits plays an important role in magnetometry based on nitrogen-vacancy (NV) centers in diamonds. However, the nontrivial spin-spin coupling of the NV center decreases signal contrast and sensitivity. Here, we overcome this limitation by exploiting the amplitude modulation of microwaves, … Webb2. Coherent manipulation of single spins. We first introduce the basic spin and optical properties of NV centers in diamond. A six-electron model has been generally accepted to explain the energy levels of the negatively charged NV − center. [] As shown in Fig. 1(b), this spin-1 system has ground states of an 3 A spin triplet, with a zero-field splitting 2.87 GHz …
