量子态的计算复杂性量化了它的制造难度。复杂性几何(英语:Complexity geometry)是由尼尔森(Nielsen)首先提出的一种使用微分几何工具来定义计算复杂性的方法。在这里,我们使用单个量子位的例子来展示复杂几何的许多吸引人的特征,结果证明它足够丰富,可以说明,但足够简单,可以说明。
The computational complexity of a quantum state quantifies how hard it is to make. Complexity geometry, first proposed by Nielsen, is an approach to defining computational complexity using the tools of differential geometry. Here we demonstrate many of the attractive features of complexity geometry using the example of a single qubit, which turns out to be rich enough to be illustrative but simple enough to be illuminating.
