我们找到一个通用的量子门的量子计算机，即一个阵列的两级系统的可扩展的候选人的精确解。门是由动力学和几何（非阿贝尔）相结合。以前，这些门主要是在不可扩展的系统上构建的，并且通过在哈密顿量的控制参数的流形中的循环之间进行数值搜索。
We find exact solutions for a universal set of quantum gates on a scalable candidate for quantum computers, namely an array of two-level systems. The gates are constructed by a combination of dynamical and geometrical (non-Abelian) phases. Previously these gates have been constructed mostly on nonscalable systems and by numerical searches among the loops in the manifold of control parameters of the Hamiltonian.
