Nontechnical Abstract: This project is aimed at 'braiding' of the half-flux quantum vortices. 'Braiding' means moving these quantum vortices around each other as a function of time, corresponding to quantum mechanical exchange. These vortices are believed to have unusual quantum mechanical exchange properties, and the ability to braid them is a necessary enabling step towards topological quantum computation. Therefore, the successful braiding of such vortices would be a major achievement in its own right but also a critical enabling milestone along one of the main envisioned routes towards the development of a topological quantum computer. The new ideas and technologies developed here will enable the braiding of non-abelian anyons, a concept that has so far just lived in the imagination of mathematicians and physicists. The project's broader impacts are related to the major societal impacts to which quantum computation might bring, for example, exponentially increased speeds for certain types of computations, which could then enable many new types of scientific and technological endeavors.Technical Abstract: The goal of this project is to make progress towards braiding half-flux quantum vortices in the p-wave spin-triplet superconductor Sr2RuO4. Such half-flux vortices are believed to be non-abelian anyons whose quantum exchange should be distinct from that of fermions and bosons. The braiding of these anyons is considered to be a major enabling step along one of the main envisioned routes towards the development of a topological quantum computer. Efforts in this project include the synthesis of the Sr2RuO4 materials, the testing of the materials, the device fabrication using these materials, as well as a theoretical program to address some of the issues that might be encountered along the way. While this program is unusually challenging and therefore of high risk, the potential rewards for its success are also very high, as it might enable quantum computation protected from many aspects of decoherence.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

非技术摘要：该项目旨在“半流量量子涡旋”的“编织”。 “编织”是指与量子机械交换相对应的时间的函数，将这些量子涡流互相移动。据信这些涡旋具有异常的量子机械交换特性，并且将它们编织的能力是迈向拓扑量子计算的必要步骤。因此，这种涡流的成功编织本身就是一项重大成就，但也是沿着沿着拓扑量子计算机开发开发的主要设想的一条主要设想的里程碑的关键成就。这里开发的新思想和技术将使非亚伯式的人的编织能够编织，这个概念迄今为止生活在数学家和物理学家的想象中。该项目的更广泛的影响与量子计算可能带来的主要社会影响有关，例如，某些类型的计算可以成倍提高速度，然后可以使许多新型的科学和技术努力摘要。技术摘要：该项目的目的是在将半流量的量子量从p-wave spret-spret-spret-sprout-sproutorcruct-prucondorcruct-sproutorcruct-prucondorcruct-prucroutcr中塑造出来。据信，这种半流量涡流是非亚洲的任何人，其量子交换应与费米子和玻色子不同。这些人的编织被认为是沿着拓扑量子计算机开发的主要设想的一条途径之一，这是一个主要的促进步骤。该项目的努力包括综合SR2RUO4材料，材料的测试，使用这些材料制造的设备制造，以及一个理论计划，以解决沿途可能遇到的一些问题。尽管该计划异常具有挑战性，因此具有很高的风险，但其成功的潜在回报也很高，因为它可能可以保护量子计算受到逆转的许多方面的保护。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的审查审查标准来通过评估来获得支持的。
