This Information Technology Research (ITR) medium program will develop ultrafast optical methods for controlling electronic, magnetic, vibrational, and excitonic properties of semiconductors for fast information processing. Successful manipulation of quantum states and processes in solids will be a necessary breakthrough for implementing the emerging technologies of spintronics and quantum information science. Optical control, as opposed to electrical control, has the advantage of performing quantum control on femtosecond time scales, which will be explored in the following specific contexts: (1) Optical control of ferromagnetism in magnetic III-V semiconductors, (2) optical control of band structure via the dynamic Franz-Keldysh effect, (3) optical control of electric fields in GaN/InGaN strain superlattices, and (4) optical control of excitons in coupled quantum wells. The proposed research work will train student researchers for future employment in high technology fields such as nanoscience and quantum information science and to produce scientists and engineers with a strong background in spectroscopy, optics, photonics, solid state theory, many-body theory, and quantum information theory. New courses on nanotechnology and quantum information science will be developed in the Applied Physics curricula at Rice University, the University of Florida, and the University of California at San Diego.This Information Technology Research (ITR) medium program is focused on fundamental studies of control of quantum electron dynamics. It will develop 'designer' electronic processes for applications in the emerging fields of spin-based electronics and quantum information processing. The passive paradigm of studying natural processes is replaced by the active one of designing controls of electron and crystal motion at the quantum level. Advanced lasers are used to control motion at the time scale between a trillionth and a quadrillionth of a second. Molecular beam fabrication of nanostructures is used to confine the electrons to a spatial dimension around a billionth of a meter. Such a space-time regime between that of the smallest macroscopic device extant and the microscopic regime of the elementary particles may be advantageous for quantum control and will be explored to utilize the electron spin as an extra dimension for information processing and to produce desirable magnetic, electrical and transport properties at will. The program contains a strong effort in providing interdisciplinary education and research experience in nanoscience and quantum optics. It prepares students for future employment in the increasingly quantum-oriented world of high technology.

这个信息技术研究（ITR）媒体计划将开发超快光学方法，用于控制半导体的电子，磁性，振动和激子特性，以实现快速信息处理。 成功操纵固体中的量子态和过程将是实现自旋电子学和量子信息科学新兴技术的必要突破。 与电控制相反，光学控制具有在飞秒时间尺度上执行量子控制的优势，这将在以下特定背景下进行探索：（1）磁性III-V族半导体中铁磁性的光学控制，（2）通过动态Franz-Keldysh效应的能带结构的光学控制，（3）GaN/InGaN应变超晶格中电场的光学控制，（4）耦合量子威尔斯中激子的光学控制。 拟议的研究工作将培养学生研究人员未来在纳米科学和量子信息科学等高科技领域就业，并培养在光谱学，光学，光子学，固态理论，多体理论和量子信息理论方面具有强大背景的科学家和工程师。 莱斯大学、佛罗里达大学和加州大学圣地亚哥分校的应用物理学课程中将开发有关纳米技术和量子信息科学的新课程。这一信息技术研究（ITR）中等计划的重点是量子电子动力学控制的基础研究。 它将为自旋电子学和量子信息处理等新兴领域的应用开发“设计师”电子工艺。 研究自然过程的被动范式被在量子水平上设计电子和晶体运动控制的主动范式所取代。 先进的激光器被用来控制运动的时间尺度在万亿分之一秒和千万亿分之一秒之间。 纳米结构的分子束制造用于将电子限制在十亿分之一米左右的空间维度。 这种介于现存最小的宏观器件和基本粒子的微观区域之间的时空区域对于量子控制可能是有利的，并且将被探索以利用电子自旋作为信息处理的额外维度，并且随意产生期望的磁、电和输运性质。 该计划包含在纳米科学和量子光学提供跨学科的教育和研究经验的强大努力。 它为学生在日益量子化的高科技世界中未来的就业做好准备。
