金刚石氮空位中心成为量子计算和量子信息的热点方向之一，在室温下用光学和微波脉冲就能初始化、操控以及读出电子自旋态，中心的电子自旋有较长的退相干时间，可以和其它量子比特实现相干耦合，进行多比特量子计算是未来发展趋势。氮空位中心近邻的多个核自旋是实现多量子比特优秀候选者。核自旋具有超长的退相干时间，如果两个比特都是核自旋，那它们的相干性可以保持在同一时间尺度，基于此我们拟在室温下对纯净金刚石单晶样品中氮空位中心近邻的核自旋进行精确的定位和测量，利用动力学解耦脉冲操控和射频脉冲操控结合的方式，设计和实施核自旋的单比特和双比特普适量子逻辑门，最终在核自旋上实现双量子比特的Deutsch-Jozsa算法演示。

Recently nitrogen-vacancy center in diamond becomes one of the most important field in quantum information and computation. At room temperature the electron spin state can be initialized, manipulated and read out by using optical excitation and microwave. Its electron spin has very long coherence time and can be coupled with other qubits. The nuclear spins in diamond can be great candidate for multi qubits computing. Because the decoherence time for both nuclear spin has the same time scale so there is no requirement for extra extension of any qubit's decoherence time. We plan to use two nuclear spins to demonstrate a simple quantum algorithm. We will demonstrate coherent control of nuclear spin nearby nitrogen vacancy center. By using RF pulse and dynamical decoupling technique we can control nuclear spins and demonstrate quantum logic gate operation and finally show the Deutsch-Jozsa quantum algorithm.
