摘要
处理了离子阱中量子受控非门的操作出错问题。通过增加一次投影测量 ,可以对输出结果作有效的提纯 ,使误差减至一阶小量 ,在某些情况下甚至能减小到二阶小量。
The error of the quantum controlled not operation in an ion trap is treated. By introducing a measurement of projection, the error can be reduced to be a small quantity, or a second order small quantity in some particular cases. The limitation of this scheme is discussed.
