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的技术不可能实现的方式传输和处理信息。该项目正在开发一种量子频率转换新技术——一种在单光子或少光子水平上运行的无噪声波长转换形式，其重要性有以下几个原因：1）用于在可见波长运行的量子存储器和用于长距离光纤传输的红外光子之间的接口，2）用于在不同但接近的波长运行的不同量子存储器之间的接口，以及3）用于移动电信波段光子 进入可见光区域，可以使用更高效的单光子探测器。智力优势在于开发高度非线性光纤中的四波混频作为实现动态布拉格散射的手段。利用这种新功能，可以通过实验实现一系列重要的过程，包括：1）谱时域中的纠缠交换； 2）双色、双光子干涉，3）单光子态的谱时变换，4）非单光子态的谱时变换（包括频率转换），5）单光子态的谱时模式滤波和复用。更广泛的影响在于量子信息技术和技术劳动力的发展，以及对普通大学生进行通信科学教育。通过将研究材料和人员与课程教学联系起来，非线性光学提供了将研究与科学教育相结合的绝佳机会。该 PI 帮助俄勒冈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”的课程。
