我们提出了一个连续时间的量子搜索算法的石墨烯晶格。这提供了在二维晶格上实现有效的连续时间量子搜索的方法。该搜索使用狄拉克点附近的色散关系的线性，并且可以比相应的经典搜索更快地找到石墨烯晶格上的标记位点。该算法也可用于状态转移和通信。
We present a continuous-time quantum search algorithm on a graphene lattice. This provides the sought-after implementation of an efficient continuous-time quantum search on a two-dimensional lattice. The search uses the linearity of the dispersion relation near the Dirac point and can find a marked site on a graphene lattice faster than the corresponding classical search. The algorithm can also be used for state transfer and communication.
