设计师非阿贝尔任意子平台:从马约拉纳到斐波那契

Designer non-Abelian anyon platforms: from Majorana to Fibonacci

Jason Alicea, Ady Stern

摘要:

从大量相互作用的基本粒子中出现非阿贝尔任意子是一个概念上美丽的现象,对容错量子计算有重要的影响。在过去的几十年里,该领域已经从一个高度理论化的课题发展成为一个活跃的实验领域,特别是在以下建议中,即在由熟知的组件构建的“工程”结构中捕获非阿贝尔任意子。在这个简短的概述中,我们简要地介绍了在寻求最简单的非阿贝尔任意子类型-缺陷结合马约拉纳零模式-方面所取得的令人印象深刻的进展,然后转向类似的策略来追求更奇异的激发。具体来说,我们描述了如何接口简单的量子霍尔系统与传统的超导体产生'parafermionic'概括的马约拉纳模式,甚至斐波那契任意子-后者使完全容错的通用量子计算。我们以一种连贯的方式统一这些主题的方式来构建我们的治疗。这里综合的想法在很大程度上突出了量子霍尔物理学领域的未知实验领域,这些领域似乎已经成熟。

英文摘要:

The emergence of non-Abelian anyons from large collections of interacting elementary particles is a conceptually beautiful phenomenon with important ramifications for fault-tolerant quantum computing. Over the last few decades the field has evolved from a highly theoretical subject to an active experimental area, particularly following proposals for trapping non-Abelian anyons in `engineered' structures built from well-understood components. In this short overview we briefly tour the impressive progress that has taken place in the quest for the simplest type of non-Abelian anyon---defects binding Majorana zero modes---and then turn to similar strategies for pursuing more exotic excitations. Specifically, we describe how interfacing simple quantum Hall systems with conventional superconductors yields `parafermionic' generalizations of Majorana modes and even Fibonacci anyons---the latter enabling fully fault tolerant universal quantum computation. We structure our treatment in a manner that unifies these topics in a coherent way. The ideas synthesized here spotlight largely uncharted experimental territory in the field of quantum Hall physics that appears ripe for discovery.
