NER: Electron Spin Resonance on a Single Carbon Nanotube

提案编号：0403582 INSTITUTION：U of Cal IrvinePRINCIPAL研究员：Burke，PeterTITLE：NER：单个碳纳米管上的电子自旋共振摘要：该研究项目整合和开发了三个相关领域的技术：自旋、纳米和量子。该研究项目将尝试测量碳纳米管内部电子自旋的量子性质。特别是，该项目将测量自旋保持其相干性的时间，即自旋保持其量子属性的时间。如果纳米管中电子的自旋相干时间足够长，那么该系统就可以作为基本量子比特(Qubit)发挥作用，量子比特是量子计算机的基础。此外，通过测量一维系统中电子自旋的量子性质，将开发和实现用于基于自旋的经典数据存储设备(如磁性硬盘驱动器)的新概念和技术，尤其是在该技术进入纳米领域时。因此，这项研究将开发一种重要的实验技术(单纳米管上的电子自旋共振)，并对与量子计算的物理实现直接相关的属性进行具体测量：单纳米管中电子的自旋相干时间。拟议活动的智力优势是开发了一种新的技术来控制纳米电子系统中的自旋自由度。这将是一个关键的进步，将导致巨大的强大的信息处理系统。拟议活动的更广泛影响将是让来自以少数民族为主的社区的教育困难学生参加微型和纳米制造方面的联合动手和远程学习练习，为这些学生提供少数族裔本科生榜样，通过直接参与研究和教育推广，培训这些本科生从事科学、工程和教学工作，并促进加州大学研究人员与当地K-12教师之间的伙伴关系。

PROPOSAL NO: 0403582INSTITUTION: U of Cal IrvinePRINCIPAL INVESTIGATOR: Burke , PeterTITLE: NER: Electron spin resonance on a single carbon nanotubeAbstract:This research project integrates and develops technology in three related areas: spin, nano, and quantum. The research project will attempt to measure the quantum properties of the spin of an electron inside of a carbon nanotube. In particular, the project will measure how long the spin maintains its coherence, i.e. how long the spin maintains its quantum properties. If the spin-coherence time of electrons in a nanotube is long enough, then the system could function as an elementary quantum bit (qubit), the building block of quantum computers. Furthermore, by measuring the quantum properties of electron spin in one-dimensional systems, new concepts and technologies useful for spin based classical data storage devices (such as magnetic hard drives) will be developed and realized, especially important as the technology moves into the nanometer domain. Thus, the research will both develop an important experimental technique (electron spin resonance on a single nanotube) as well as performing a specific measurement of a property directly related to the physical implementation of quantum computing: the spin coherence time of electrons in a single nanotube.The intellectual merit of the proposed activity is the development of a new technique to control the spin degree of freedom in nano-electronic systems. This will be a crucial advance that leads to enormously powerful information processing systems. The broader impact of the proposed activity will be to involve educationally disadvantaged students from neighborhoods with predominately ethnic-minority student populations in combo hands-on and distance learning exercises in micro and nanofabrication, to provide minority undergraduate role models for these students, to train these undergraduates for careers in science, engineering, and teaching through direct participation in both research and educational outreach, and to promote partnerships between University of California researchers and local K-12 teachers.
