论文摘要
我们建议将扣板用作量子，其中通过将板从两侧推动来机械产生双孔电势。板的左右位置分配为量子状态$ | 0 \ rangle $和$ | 1 \ rangle $。当位移是皮仪的顺序时，量子效应会出现，尽管扣板的大小为$1μm$。 NOT门是通过更改作用在板上的屈曲力来执行的，而Pauli-Z门和相移门是通过应用电场执行的。使用静电电势实现了两数Qubit的相移门。它们构成了一组通用量子门。对材料参数的检查会导致基于NEMS（纳米电机机械系统）的量子计算机的可行性。
We propose to use a buckled plate as a qubit, where a double-well potential is mechanically produced by pushing the plate from both the sides. The right and left positions of the plate are assigned to be quantum states $|0\rangle $ and $|1\rangle $. Quantum effects emerge when the displacement is of the order of picometers, although the size of a buckled plate is of the order of $1μm$. The NOT gate is executed by changing the buckling force acting on the plate, while the Pauli-Z gate and the phase-shift gate are executed by applying electric field. A two-qubit phase shift gate is materialized with the use of an electrostatic potential. They constitute a set of universal quantum gates. An examination of material parameters leads to a feasibility of a NEMS(Nano-Electro-Mechanical System)-based quantum computer.
