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.

该计划的目标是开发基于光子的量子信息技术，以使用基于经典物理学的技术不可能的方式传输和处理信息。这个项目正在开发一种新的量子频率转换技术？- 在单光子或少光子水平下操作的无噪声形式的波长转换，这是重要的，原因如下：1）用于在可见波长下操作的量子存储器与用于长距离光纤传输的红外光子之间进行接口，2）用于在不同但邻近的波长下操作的不同量子存储器之间进行接口，以及3）用于将电信波段的光子转移到可见光中，在可见光中可获得更高效率的单光子探测器。其智力上的优点是在高度非线性光纤中发展四波混频，作为实现动态布拉格散射的一种手段。利用这种新的能力，有一个广泛的重要过程进行实验，包括：1）纠缠交换在光谱-时间域; 2）双色双光子干涉; 3）单光子态的谱-时变换; 4）谱-时变换（包括频率平移）除了单光子状态之外的状态，5）单光子态的光谱-时间模式滤波和多路复用。更广泛的影响是量子信息技术和发展技术劳动力，以及在通信科学方面教育普通大学生。非线性光学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帮助俄勒冈州大学启动了一个新的科学素养项目，并开发了一门名为互联网背后的物理学的课程。
