论文摘要
控制（氮 - 视态）NV中心量子的自动量方法提供了一种优雅的方法，即理论上设计了通用量子门，通过可计算的微波脉冲在Qubits上运行。但是，由于对量子登记的人体控制理论缺乏模拟结果，其中有两个以上的量子位描述了黑暗状态之间的过渡。鉴于此，我们一直在尝试使用IBM量子体验技术，以确定三个量子位的NV中心模拟全体性控制的能力，描述了一个八级系统，该系统产生了一个非亚洲几何阶段。几何阶段通过引人注目的频率可调节性通过3 Q Q Quit的高谐波自变量大门的高保真度（约80％）证明。黑暗状态之间的过渡表明，栅极暗状态与Qubits初始状态的对齐，因此，多Qubit System的分辨率通过0.33pi旋转很好地控制了。基于额外的几何阶段在拓扑材料中观察到的电子返回概率可以表现出旋转轨道耦合行为。
The holonomic approach to controlling (nitrogen-vacancy) NV-center qubits provides an elegant way of theoretically devising universal quantum gates that operate on qubits via calculable microwave pulses. There is, however, a lack of simulated results from the theory of holonomic control of quantum registers with more than two qubits describing the transition between the dark states. In light of this, we have been experimenting with the IBM Quantum Experience technology to determine the capabilities of simulating holonomic control of NV-centers for three qubits describing an eight-level system that produces a non-Abelian geometric phase. The tunability of the geometric phase via the detuning frequency is demonstrated through the high fidelity (about 80%) of 3-qubit off-resonant holonomic gates over the on-resonant ones. The transition between the dark states shows the alignment of the gate dark state with the qubits initial state hence decoherence of the multi-qubit system is well-controlled through a 0.33pi rotation. The electron return probability can exhibit spin-orbit coupling-like behavior as observed in topological materials based on the extra geometric phase.
