关于旋转量子比特

On Rotating a Qubit

Subhash Kak

摘要:

量子物体的态函数相对于其相位是不确定的。如果这种不确定性是全局性的,那么它就不重要了,但是如果状态的各个组成部分具有未知的相对相位呢?尽管存在这种局部不确定性,仍然可以进行有用的计算吗?我们考虑这个问题的量子比特的旋转的问题,并研究其更广泛的影响量子计算。

英文摘要:

The state function of a quantum object is undetermined with respect to its phase. This indeterminacy does not matter if it is global, but what if the components of the state have unknown relative phases? Can useful computations be performed in spite of this local indeterminacy? We consider this question in relation to the problem of the rotation of a qubit and examine its broader implications for quantum computing.
