摘要
提出了一种利用电子-核子自旋的半导体固体量子计算机实现方案,通过扫描隧道显微镜的针尖实现单个比特的寻址、操作以及任意两个比特之间的受控非门操作,方案中所涉及到的技术是目前已有的或者是接近于现有的技术水平,所提出的方案有可能利用现有的技术来实现。
A solid-state quantum computer scheme using electron-nucleon double spins is proposed.The addressing of qubit.single qubit operation and the control-not gate between any two qubits are realized by using an STM tip.The technique in-volved in this scheme is either current available or very close to the present technical expectation.Thus the scheme may be re-alized using existing technologies.
