Center for Integrated Quantum Materials

****摘要***集成量子材料科学技术中心（STC）是由哈佛大学、霍华德大学、麻省理工学院（MIT）和波士顿科学博物馆合作建立的，并得到了大量国际合作者的支持。C-IQM通过与“学院网络”的持续互动得到进一步加强和补充，该网络由来自波士顿地区的霍利奥克山学院、奥林学院和韦尔斯利学院以及华盛顿特区的加劳德特大学和乔治王子社区学院的研究人员和教师组成。该中心的重点是利用最近发现的量子材料，通过综合研究、教育、知识转移和通过国际机会增强多样性的综合方法来改变信号处理和计算。这些新的量子材料正在改变竞争环境，并有望彻底重塑现代技术。C-IQM的智力优势在于它协同整合了凝聚态物理前沿的三个研究领域：(1)石墨烯(G)与电子以恒定速度作为无质量粒子运动；(2)拓扑绝缘体（Topological Insulators， TI），其中可移动的表面电子具有固定于运动方向的自旋；金刚石中的氮空位（NV）中心，其中单个自旋存储“比特”量子信息。C-IQM利用了这些材料所显示的量子现象，通过持续到室温，导致信号处理和计算规则的变化，最终为量子电子学开辟了道路。这些量子材料非常适合集成到层状处理器结构中，其中石墨烯和拓扑绝缘体控制电荷和自旋的流动，金刚石中的nv中心提供存储位置和光输入/输出通道。石墨烯和拓扑绝缘体的分层是自然的，它们的表面有二维电子系统。C-IQM的任务是了解量子材料的独特电子行为，并寻求一个令人兴奋的机会来观察极其难以捉摸的马约拉纳费米子，一种本身就是反粒子的粒子。该中心开发的量子电子学将为信号处理、计算和太赫兹电子学提供新的方法。C-IQM的更广泛影响体现在开发新型量子电子设备和系统的战略目标中，这些设备和系统将改变信号处理和计算。C-IQM的另一个同样重要的目标是吸引学生学习科学和工程，并为他们提供成为未来领导者的令人兴奋的机会。该中心的研究和教育项目汇集了一个多元化的社区，通过涉及本科生和研究生，博士后助理，教授，行业和公众来应对这些挑战。该中心的愿景与国家研究和教育战略重点明确一致。

****Abstract***The Science and Technology Center (STC) on Integrated Quantum Materials (C-IQM) is a partnership involving Harvard University, Howard University, Massachusetts Institute of Technology (MIT), and the Boston Museum of Science, complemented by a large number of International collaborators. C-IQM is further strengthened and complemented by constant interactions with the "College Network" comprising partnership with investigators and teachers from Mount Holyoke, Olin and Wellesley Colleges in the Boston area, as well as with Gallaudet University and Prince George's Community College in the Washington D.C area. The focus of the Center is to use the recent discovery of quantum materials to transform signal processing and computation through an integrated approach that incorporates research, education, knowledge transfer, and increased diversity enhanced by international opportunities. These new quantum materials are changing the playing field and show promise to completely reshape modern technology.The intellectual merit of the C-IQM is that it integrates synergistically three research areas at the forefront of condensed matter physics: (1) Graphene (G) with electrons that move as massless particles at a constant speed; (2) Topological Insulators (TI) where mobile surface electrons have spins fixed to the direction of motion; and (3) Nitrogen Vacancy (NV) Centers in diamond where a single spin stores a "bit" of quantum information. C-IQM takes advantage of the quantum phenomena displayed by these materials which, by persisting up to room temperature, lead to changes in the rules for signal processing and computation, ultimately opening the way for quantum electronics. These quantum materials are ideally suited for integration into layered processor structures, in which Graphene and Topological Insulators control the flow of charge and spin, and NV-centers in diamond provide memory sites and optical input/output channels. Layering is natural for Graphene and Topological Insulators, which have two-dimensional electron systems on their surface. The C-IQM mission is to understand the unique electronic behavior of quantum materials and pursue an exciting opportunity to observe the exceedingly elusive Majorana fermion, a particle which is its own antiparticle. Quantum electronics developed in the Center will offer new approaches to signal processing, computing, and THz electronics. The broader impacts of the C-IQM are found in the strategic goal to develop a new class of quantum electronic devices and systems that will transform signal processing and computation. An equally important goal of C-IQM is to attract students to science and engineering, and to provide them with exciting opportunities to become future leaders. The Center's research and education programs bring together a diverse community to address these challenges by involving undergraduate and graduate students, postdoctoral associates, professors, industry and the public. The vision of the Center is clearly aligned with the national research and education strategic priorities.
