标题： Spin-liquid-based topological qubits

摘要： 拓扑量子计算依赖于对非阿贝尔任意子的控制，以实现固有的容错量子信息存储和处理。 截至目前，拓扑量子位的蓝图已在电活性拓扑超导体和分数量子霍尔平台中得到了充分发展。 我们利用最近在电绝缘自旋系统中创建和检测非阿贝尔任意子的见解，提出了基于量子自旋液体的拓扑量子位架构。 我们介绍了两种原型设计，这些设计在潜在可扩展的框架中实现了必要的控制：一种涉及集成到磁性隧道结阵列中的自旋液体，另一种使用半导体-自旋液体混合结构。 我们进一步确定了各种用于探测基于自旋液体的拓扑量子位的协议，既可用于验证拓扑量子计算的基本原理，也可用于建立通用量子计算所需的逻辑门。 这些结果为Kitaev材料及其他潜在固体自旋液体宿主的实验研究提供了长期方向。 显示英文摘要

摘要： Topological quantum computation relies on control of non-Abelian anyons for inherently fault-tolerant storage and processing of quantum information. By now, blueprints for topological qubits are well developed for electrically active topological superconductor and fractional quantum Hall platforms. We leverage recent insights into the creation and detection of non-Abelian anyons in electrically insulating spin systems to propose topological qubit architectures based on quantum spin liquids. We present two types of prototype designs that enable the requisite control in a potentially scalable framework: one invokes spin liquids integrated into magnetic tunnel junction arrays, the other uses semiconductor-spin liquid hybrids. We further identify various protocols for interrogating spin-liquid-based topological qubits, both to validate the underlying principles of topological quantum computation and to establish gates required for universal quantum computation. These results provide long-term direction for experimental investigation of Kitaev materials and potentially other solid-state spin liquid hosts.
