项目摘要

The last ten years have seen an explosion in the potential for topology to affect our everyday lives through electronics. When many of us think of topology, we think of a Mobius strip demonstration in high school, or an esoteric branch of mathematics, but in fact several recent discoveries have connected these abstract concepts with applications that may change the way electronics and information processing works in the future. For example, so-called topological insulators may be developed that enable computer chips to run with markedly lower energy loss.******An even more revolutionary connection between topology and electronics is the recent theoretical developments, and experimental hints, that new kinds of particles can be created in a table-top device that have very counterintuitive--but useful--topological characteristics. These would be particles like electrons, but unlike electrons they would retain a memory of the paths they have followed in the past. Take two of these particles, and move one around the other so it comes back to the same place. The particles look the same, but both particles' quantum mechanical states have completely changed due just to this looping operation. If these predictions turn out to be true, it will open new avenues for quantum computing that do not suffer from the same challenges of current approaches.******Here, we propose a head-on assault on the challenge of bringing topology to bear in electronics. Working closely with the two top groups in the world in this area, we aim in five years to make the first electronic devices whose operation depends on particles with non-trivial topologies like those described above.**

在过去的十年中，拓扑的爆炸可能会通过电子产品影响我们的日常生活。当我们许多人想到拓扑时，我们会想到高中的Mobius脱衣舞演示，或者是数学的深奥分支，但实际上，最近的一些发现将这些抽象概念与可能会改变未来电子产品和信息处理的应用联系起来。例如，可以开发出所谓的拓扑绝缘子，使计算机芯片能够以明显降低的能源损失来运行。******拓扑和电子设备之间的更具革命性的联系是最近的理论发展和实验性的提示，即可以在具有非常相反的 - 抗直觉 - 且有用的有用的用途的台式设备中创建的新型粒子。这些是像电子这样的粒子，但是与电子不同，它们会保留对过去遵循的路径的记忆。取两个颗粒，然后将一个粒子移动到另一个粒子，以便返回同一位置。颗粒看起来相同，但是由于这种循环操作，两个粒子的量子机械状态已经完全改变。如果这些预测是正确的，它将为不会遇到当前方法挑战的量子计算开辟新的途径。与该领域的世界上两个顶级团体紧密合作，我们的目标是在五年内制造第一个电子设备，其操作取决于具有如上所述的非平凡拓扑的粒子。**
