论文摘要
实现高保真量子门的主要挑战是减少由不完善的汉密尔顿人引起的控制误差的影响，以及由环境噪声引起的变形的影响。为了克服控制误差，有希望的建议是非绝热的全体量子计算，这在理论和实验中都引起了很多关注。尽管已经充分利用了抵抗控制误差的自动操作的优点，但以下一个重要的问题是如何缩短实现自动栅极所需的进化时间，以避免尽可能多地避免环境噪声的影响。在本文中，我们提出了一种为非绝热全体量子计算构建哈密顿量的一般方法，这使得可以最大程度地减少演变时间，并可能为非绝热全能量子计算的现实实施打开新的地平线。
The main challenges in achieving high-fidelity quantum gates are to reduce the influence of control errors caused by imperfect Hamiltonians and the influence of decoherence caused by environment noise. To overcome control errors, a promising proposal is nonadiabatic holonomic quantum computation, which has attracted much attention in both theories and experiments. While the merit of holonomic operations resisting control errors has been well exploited, an important issue following is how to shorten the evolution time needed for realizing a holonomic gate so as to avoid the influence of environment noise as much as possible. In this paper, we put forward a general approach of constructing Hamiltonians for nonadiabatic holonomic quantum computation, which makes it possible to minimize the evolution time and might open a new horizon for the realistic implementation of nonadiabatic holonomic quantum computation.
