The vision of creating fully controlled spatial and temporal quantum mechanical electron waves will be realized in the near future. Such coherent electron control offers exciting possibilities for the development of new technologies and the exploration of new physics. The challenge to combine very small (nanometer scale) parts with ultrafast (femto- and atto-second) lasers to control electrons is going to be addressed by the work funded through this grant. The largest enclosed area electron interferometer ever will be built, and electron switches directing signals at extreme rates of about a million GigaHertz will be explored. The impact of having a largest electron interferometer (that still fits in a car) is that new frequency ranges and sensitivities of electromagnetic fields can be tested. The use of a simple low frequency magnetometer is explored together with Honeywell and these devices are applicable for hunting submarines and locating mines. Higher frequencies are used for detecting electromagnetic communications. On the scientific side, the interferometer will be used to help understand one of the largest puzzles of the century, which is the transition between classical and quantum physics. The impact of having ultrafast electron switches is that this may enable a new generation of devices, such as the fastest microscopes, oscilloscopes and signal processors. The educational impact is that training for graduate students will be provided in an area of national need, while previous outreach has already reached an estimated 100,000 high school students. This grant will allow a continuation of these efforts.

创造完全受控的空间和时间量子力学电子波的愿景将在不久的将来实现。这种相干电子控制为新技术的发展和新物理的探索提供了令人兴奋的可能性。将非常小的（纳米级）部件与超快（飞秒和阿秒）激光器结合起来控制电子的挑战将通过这项资助的工作来解决。将建造有史以来最大的封闭区域电子干涉仪，并将探索以大约100万千兆赫兹的极端速率引导信号的电子开关。拥有最大的电子干涉仪（仍然适合汽车）的影响是可以测试电磁场的新频率范围和灵敏度。与Honeywell公司一起探讨了使用一种简单的低频磁力计的问题，这些装置可用于搜索潜艇和确定地雷的位置。更高的频率用于检测电磁通信。在科学方面，干涉仪将被用来帮助理解世纪最大的难题之一，即经典物理学和量子物理学之间的过渡。拥有超快电子开关的影响是，这可能会使新一代设备成为可能，例如最快的显微镜，电子显微镜和信号处理器。教育方面的影响是，将在国家需要的领域为研究生提供培训，而以前的外联活动已经接触到大约100 000名高中生。这笔赠款将使这些努力得以继续。
