Quantum computers have the potential to speed up certain problems that are hard for classical computers. Hybrid systems, such as the nitrogen-vacancy (NV) center in diamond, are among the most promising systems to implement quantum computing, provided the control of the different types of qubits can be efficiently implemented. In the case of the NV center, the anisotropic hyperfine interaction allows one to control the nuclear spins indirectly, through gate operations targeting the electron spin, combined with free precession. Here, we demonstrate that this approach allows one to implement a full quantum algorithm, using the example of Grover’s quantum search in a single NV center, whose electron is coupled to a carbon nuclear spin.

在单个钻石空缺中心内量子算法的高效实现。

量子计算机具有加速某些传统计算机难以解决的问题的潜力。混合系统,例如钻石中的氮空位(NV)中心,是可以实现量子计算的最有希望的系统之一,只要可以有效地实现对不同类型量子位的控制。在NV中心的情况下,各向异性的超精细相互作用使得人们可以通过针对电子自旋的门操作结合自由进动来间接控制核自旋。在这里,我们以格鲁弗(Grover)在单个NV中心的量子搜索为例,证明了这种方法可以实现完整的量子算法,该中心的电子与碳核自旋耦合。
