我们提出了一种实验上可行的方案来实现基于非绝热几何相移的量子计算，其中使用循环几何相来实现一组通用量子门。这组门的物理实现是为约瑟夫森结和 NMR 系统设计的。有趣的是，我们发现在适当的可控条件下，非绝热相移可能与操作时间无关。当前非绝热几何门的一个显着特征是操作时间没有内在限制。
We propose an experimentally feasible scheme to achieve quantum computation based on nonadiabatic geometric phase shifts, in which a cyclic geometric phase is used to realize a set of universal quantum gates. Physical implementation of this set of gates is designed for Josephson junctions and for NMR systems. Interestingly, we find that the nonadiabatic phase shift may be independent of the operation time under appropriate controllable conditions. A remarkable feature of the present nonadiabatic geometric gates is that there is no intrinsic limitation on the operation time.
