论文摘要
实施量子协议和量子信息处理（QIP）的最大挑战之一是达到较长的连贯时间，通常需要在超低温度下进行系统。钻石中的氮呈（NV）中心是该问题的有前途替代方法。由于其自旋特性，易于操作以及进行光学状态初始化和读数的可能性，它很快成为室温下QIP最好的固态旋转系统之一。在这里，我们介绍了NV中心集合的自旋连接性在工程的超音钻头样本中，作为用于量子计量学量子方案的测试床。
One of the biggest challenges to implement quantum protocols and quantum information processing (QIP) is achieving long coherence times, usually requiring systems at ultra-low temperatures. The nitrogen-vacancy (NV) center in diamond is a promising alternative to this problem. Due to its spin properties, easy manipulation, and the possibility of doing optical state initialization and readout, it quickly became one of the best solid-state spin systems for QIP at room temperature. Here, we present the characterization of the spin-coherence of an ensemble of NV centers in an engineered sample of ultrapure diamond as a testbed for quantum protocols for quantum metrology.
