钻石为量子计算、量子通信等量子技术提供了独特的技术平台。控制光学活性缺陷的制造是这种量子工具箱的关键要素。本文报道了利用碳离子的高能注入在蓝色光谱区域产生单色中心。我们证明了单植入缺陷显示出发射光子的亚泊松统计量，可以作为量子密码学中的单光子源进行探索。470.5 nm强零声子线可以明确地识别该缺陷为间隙相关的TR12色中心。
Diamond provides unique technological platform for quantum technologies including quantum computing and communication. Controlled fabrication of optically active defects is a key element for such quantum toolkit. Here we report the production of single color centers emitting in the blue spectral region by high energy implantation of carbon ions. We demonstrate that single implanted defects show sub-poissonian statistics of the emitted photons and can be explored as single photon source in quantum cryptography. Strong zero phonon line at 470.5 nm allows unambiguous identification of this defect as interstitial-related TR12 color center.
