摘要
六方碳化硼(hBN)中的原子样本缺陷提供室温单光子发射和相干自旋态，使其成为量子计算和感知应用的有力候选人。然而，其随机的空间和光谱特征阻碍了与纳米光学腔体的确定性耦合，限制了其作为亮度单光子源和灵敏量子传感器的潜力。本文报道了 hBN 中单光子发射器的 tip-enhanced 量子感知光谱。通过对单个发射器在具有不同等离子共振的 tip-cavity 中的精确空间定位，我们可适应性地控制激发和发射的增强率以及单光子纯净度。从而，通过 optimal selection of their relative contributions can effectively reconfigure solid-state single-photon sources, with simultaneous nano-spectroscopic space- and time-resolved analyses. Furthermore, we demonstrate tip-enhanced quantum-sensing with single spin defects through optically detected magnetic resonance (ODMR) experiments in tip-coupled hBN nanoflakes. Our approach provides a unique pathway toward highly-sensitive and deterministic quantum-sensing with room-temperature single-photon emitters.
