Moore-Read拓扑量子寄存器的自旋织构读出
Spin texture readout of a Moore-Read topological quantum register
摘要:
我们研究的复合带电自旋织构(CST)的Moore-Read量子霍尔态时出现的基本CST的集合移动到同一位置。根据Moore-Read态的特征对相关性的代数方法,我们发现所得到的CST是由底层非阿贝尔准粒子的融合扇区设置的。这种现象提供了一种新的方法来读出非阿贝尔拓扑有序相的量子寄存器。
英文摘要:
We study the composite Charged Spin Texture (CST) over the Moore-Read quantum Hall state that arises when a collection of elementary CSTs are moved to the same location. Following an algebraic approach based on the characteristic pair correlations of the Moore-Read state, we find that the resulting CST is set by the fusion sector of the underlying non-Abelian quasiparticles. This phenomenon provides a novel way to read out the quantum register of a non-Abelian topologically ordered phase.
