This program is for theoretical research and education for a revolutionary recent idea for quantum computation, known as topological quantum computation (TQC). TQC has been shown to be free of many of the serious problems facing other more conventional means of quantum computation. Although this has been proved as a point of principle in mathematics, suitable platforms to support TQC are yet to be found in nature and this program addresses this issue. In the absence of suitable natural platforms, the PIs will devise practical methods to artificially induce the desired properties for TQC on cold atom systems and semiconductors. They will also develop the appropriate TQC architectures on the considered physical systems and study the fundamental limits on quantum coherence due to thermal and disorder effects in the various TQC platforms. In contrast to other, more "conventional" means of quantum computation, TQC is inherently fault-tolerant and scalable. The studies performed in this program, consisting of TQC platforms, limits on quantum coherence, and suitable computation architectures, will result in TQC being one step closer to experimental realization. The program will seek to realize synthetic TQC platforms and to design appropriate TQC architectures. A deep theoretical understanding of the fundamental limits of quantum protection in these systems would not only pioneer coherent control of quantum information, but would also influence the basic strongly-correlated atomic and electronic physics in the classroom. The latter has broader impact beyond the field of quantum computation. This research will foster training of graduate students at both Washington State University and Clemson University at the interface of quantum information science, atomic physics, condensed matter physics, and numerical methods. The diverse nature of this training will prepare the students in a multidisciplinary employment market. This research will also help both universities update the physics curriculum to reflect the modern trends in science and technology. Per NSF mission of promoting science and engineering education, these integrated research and education activities will promote the participation of undergraduate and graduate students from the state of Washington and the EPSCoR state of South Carolina in science and technology, and will improve the two states' long-term infrastructure.

该计划是理论研究和教育的一个革命性的量子计算的最新想法，被称为拓扑量子计算（TQC）。TQC已经被证明没有其他更传统的量子计算方法所面临的许多严重问题。虽然这已经被证明是一个数学的原则点，但在自然界中还没有找到合适的平台来支持TQC，这个程序解决了这个问题。在缺乏合适的天然平台的情况下，PI将设计实用的方法来人工诱导冷原子系统和半导体上TQC所需的特性。他们还将在所考虑的物理系统上开发适当的TQC架构，并研究由于各种TQC平台中的热和无序效应而导致的量子相干性的基本限制。与其他更“传统”的量子计算方法相比，TQC具有内在的容错性和可扩展性。在该计划中进行的研究，包括TQC平台，量子相干性的限制和合适的计算架构，将导致TQC更接近实验实现。该计划将寻求实现综合全面质量管理平台，并设计适当的全面质量管理架构。对这些系统中量子保护的基本限制的深刻理论理解不仅将开创量子信息的相干控制，而且还将影响课堂上基本的强相关原子和电子物理。后者具有超越量子计算领域的更广泛影响。这项研究将促进培训研究生在华盛顿州立大学和克莱姆森大学在量子信息科学，原子物理学，凝聚态物理学和数值方法的接口。这种培训的多样性将为学生在多学科就业市场做好准备。这项研究也将有助于两所大学更新物理课程，以反映现代科学和技术的趋势。根据NSF促进科学和工程教育的使命，这些综合研究和教育活动将促进来自华盛顿州和南卡罗来纳州EPSCoR的本科生和研究生参与科学和技术，并将改善这两个州的长期基础设施。
