摘要

提出了一种用于量子计算的一组和两组量子比特门的固态实现。量子比特被定义为电子沿着两条量子线运行的状态，通过具有可变高度和/或宽度的势垒适当地耦合。单量子比特门是利用两根导线之间的耦合实现的。使用库仑耦合器设计了两个量子比特的门，以诱导两个量子比特的相互相位调制。使用时间相关的二维薛定谔求解器进行了多次运行。

Two-qbit gates based on coupled quantum wires

A solid-state implementation of a set of one- and two-qbit gates for quantum computing is proposed. The qbit is defined as the state of an electron running along two quantum wires, suitably coupled through a potential barrier with variable height and/or width. Single-qbit gates are implemented using the coupling between the two wires. The two-qbit gates have been designed using a Coulomb coupler to induce a mutual phase modulation of the two qbits. A number of runs have been performed using a time-dependent 2D Schrodinger solver.
