Topological phases of matter for quantum computation

全球正在进行一项大规模建造量子计算机的努力。有一些很有前途的方法是基于具有奇异拓扑性质的物质的量子相，利用这些方法来保护脆弱的量子信息。该项目旨在利用最近在三维拓扑阶段的突破，发现新材料，并为量子计算机设计更好的组件。这解决了一个重要的问题，即在全尺寸量子计算机中晶体管的模拟将是什么。好处包括对三维拓扑相进行分类，以及发现更好的可伸缩量子计算方法，这可能会导致这一全球研究努力的方向发生根本性转变。

A global effort is underway to build quantum computers at scale. There are promising approaches based on quantum phases of matter with exotic topological properties that are harnessed to protect fragile quantum information. This project aims to take advantage of recent breakthroughs in three dimensional topological phases to discover new materials and design better components for quantum computers. This addresses the significant question of what the analogue of a transistor will be in a full scale quantum computer. Benefits include classification of three dimensional topological phases and the discovery of better routes to scalable quantum computing, potentially causing a fundamental shift in the direction of this global research effort.
