硅中的类氢自旋量子计算：一种数字方法
Hydrogenic Spin Quantum Computing in Silicon: A Digital Approach
摘要：
我们提出了一种硅中自旋对编码量子位的量子计算架构。电子-核自旋对受直流磁场和电极开关超精细相互作用控制。这种数字处理对调谐误差不敏感，并且易于建模。电子在供体之间穿梭使得能够实现多量子位逻辑。这些类氢自旋量子比特可转移到具有长相干时间的核自旋对和电子自旋对，它们非常适合测量和初始化。该架构可扩展到高度并行操作。
英文摘要：
We suggest an architecture for quantum computing with spin-pair encoded qubits in silicon. Electron-nuclear spin-pairs are controlled by a dc magnetic field and electrode-switched on and off hyperfine interaction. This digital processing is insensitive to tuning errors and easy to model. Electron shuttling between donors enables multi-qubit logic. These hydrogenic spin qubits are transferable to nuclear spin-pairs, which have long coherence times, and electron spin-pairs, which are ideally suited for measurement and initialization. The architecture is scalable to highly parallel operation.
