The objective of this program is to develop photon-based quantum information technology for transmitting and processing information in ways not possible using classical-physics-based techniques. This project is developing a new technique for quantum frequency translation?a noiseless form of wavelength conversion operating at the single- or few-photon level, which is important for several reasons: 1) for interfacing between quantum memory operating at visible wavelengths and infrared photons for long-distance fiber transmission, 2) for interfacing between different quantum memories operating at distinct but nearby wavelengths, and 3) for shifting telecom-band photons into the visible where higher-efficiency single-photon detectors are available. The intellectual merit is in developing four-wave mixing in highly nonlinear optical fibers as a means to implement dynamic Bragg scattering. Using this new capability there is a wide range of important processes to pursue experimentally, including: 1) entanglement swapping in the spectral-temporal domain; 2) two-color, two-photon interference, 3) spectral-temporal transformation of single-photon states, 4) spectral-temporal transformation (including frequency translation) of states other than single-photon states, 5) spectral-temporal mode filtering and multiplexing of single-photon states.The broader impacts are in quantum information technology and developing the technical workforce, as well as educating the general university student population in communications science. Nonlinear optics offers excellent opportunities to integrate research with science education, by connecting the research materials and personnel with course teaching. The PI helped start a new Science Literacy Program at the University of Oregon, and developed a course called The Physics Behind the Internet.

该程序的目的是开发基于光子的量子信息技术，以使用基于经典的物理技术的技术不可能以不可能的方式传输和处理信息。该项目正在开发一种用于量子频率翻译的新技术？一种在单个或几个光子级上运行的波长转换的无噪声形式，这很重要，这很重要，这是有几个原因的：1）在可见的波长和可见波长的量子内存之间进行连接，在可见的波长和红外光纤上进行长距离纤维传输，以在不同的量子传输之间进行互动，但要在不同的量子上进行连接，但要近距离传播范围，但要迅速在连续范围内进行循环，并在3个范围内互动。进入可见的，可以看到高效率单光子检测器。智力优点在于在高度非线性光纤中开发四波混合，以此作为实施动态布拉格散射的一种手段。使用这种新功能，有很多重要的过程可以在实验上追求，包括：1）纠缠频谱暂时性域中； 2）单光子状态的两彩，两光子干扰，3）光谱频谱转化，4）频谱时间转化（包括单光子状态以外的其他状态），5）光谱 - 周期性模式过滤和单相关状态的多重影响。对量子信息进行了更广泛的教育，并在量子信息方面进行了一般的教育，以及一般的技术工作。非线性光学器件通过将研究材料和人员与课程教学联系起来，提供了将研究与科学教育相结合的绝佳机会。 PI帮助在俄勒冈大学启动了一项新的科学素养计划，并开发了一门名为《互联网》物理学的课程。
