论文摘要
对于许多应用，例如基于自旋的量子记忆，需要在纳米级的局部磁场生成。但是，由于静态磁场的缓慢衰减，这是一个挑战。在这里，我们证明了光子自旋密度（PSD）诱导的有效静态磁场，用于散装钻石中的氮呈（NV）集合。该局部诱导的磁场是光激发与NV中心之间相干相互作用的结果。我们证明了超过10度的BLOCH球上的光学诱导的自旋旋转，该旋转在所有光学旋转Qubit的光学相干控制中具有潜在的应用。
Generation of local magnetic field at the nanoscale is desired for many applications such as spin-qubit-based quantum memories. However, this is a challenge due to the slow decay of static magnetic fields. Here, we demonstrate photonic spin density (PSD) induced effective static magnetic field for an ensemble of nitrogen-vacancy (NV) centers in bulk diamond. This locally induced magnetic field is a result of coherent interaction between the optical excitation and the NV centers. We demonstrate an optically induced spin rotation on the Bloch sphere exceeding 10 degrees which has potential applications in all optical coherent control of spin qubits.
