论文摘要
我们根据碳纳米管旋转器的链链提出了一台通用量子计算机，每个旋转器都将一个金属板连接到每个旋转器。动态变量是旋转角度$ ϕ $。连接到地面的连接板与两个固定板相互作用。两个角度位置$ ϕ = 0，π$是通过在连接板和两个固定板之间施加电压差而稳定的。我们将$ ϕ = 0 $和$π$分配给Qubit状态$ | 0 \ rangle $和$ | 1 \ rangle $。然后，考虑到旋转器链，我们构建了任意的相移门，NOT GATE和ISING GATE，构成了一组通用量子门。它们是通过控制各个板之间的电压来执行的。
We propose a universal quantum computer based on a chain of carbon nanotube rotators where one metallic plate is attached to each rotator. The dynamical variable is the rotational angle $ϕ$. The attached plate connected to ground electrostatically interacts with two fixed plates. Two angle positions $ϕ=0,π$ are made stable by applying a voltage difference between the attached plate and the two fixed plates. We assign $ϕ=0$ and $π$ to the qubit states $|0\rangle$ and $|1\rangle $. Then, considering a chain of rotators, we construct the arbitrary phase-shift gate, the NOT gate and the Ising gate, which constitute a set of universal quantum gates. They are executed by controlling the voltage between various plates.
