固体中单个核自旋的拉比章动已被观测到。实验是在金刚石中单个氮空位缺陷中心的单个电子和单个C-13核自旋上进行的。该系统用于实现量子逻辑非和条件双量子比特门（CROT）。密度矩阵层析的CROT门表明，在我们的实验中实现的门保真度高达0.9，足以用于量子算法。
Rabi nutations of a single nuclear spin in a solid have been observed. The experiments were carried out on a single electron and a single C-13 nuclear spin of a single nitrogen-vacancy defect center in diamond. The system was used for implementation of quantum logical NOT and a conditional two-qubit gate (CROT). Density matrix tomography of the CROT gate shows that the gate fidelity achieved in our experiments is up to 0.9, good enough to be used in quantum algorithms.
