Robert Raussendorf, Dongsheng Wang, Abhishodh Prakash, Tzu-Chieh Wei, David Stephen

摘要:

研究了具有保序拓扑序的量子自旋链的基态在基于测量的量子计算中的作用。我们表明,在空间维度1,如果SPTO相支持量子线,那么,受到一个额外的对称性条件,满足在所有情况下,到目前为止调查,它也可以用于量子计算。

英文摘要:

We investigate the usefulness of ground states of quantum spin chains with symmetry-protected topological order (SPTO) for measurement-based quantum computation. We show that, in spatial dimension one, if an SPTO phase supports quantum wire, then, subject to an additional symmetry condition that is satisfied in all cases so far investigated, it can also be used for quantum computation.
