摘要:

我们详细描述了一个通用的策略,用于实现两个自旋之间的条件几何相位。结合单自旋操作,这种简单的操作是量子计算的通用门,因为任何幺正变换都可以仅使用单自旋操作和条件相移以任意精度实现。因此,量子几何相位可以构成任何量子计算的基础。此外,由于诱导条件相位仅取决于自旋执行的路径的几何形状,因此它对某些类型的错误具有弹性,并提供了执行量子计算的自然容错方式的潜力。

英文摘要:

We describe in detail a general strategy for implementing a conditional geometric phase between two spins. Combined with single-spin operations, this simple operation is a universal gate for quantum computation, in that any unitary transformation can be implemented with arbitrary precision using only single-spin operations and conditional phase shifts. Thus quantum geometrical phases can form the basis of any quantum computation. Moreover, as the induced conditional phase depends only on the geometry of the paths executed by the spins it is resilient to certain types of errors and offers the potential of a naturally fault-tolerant way of performing quantum computation.
