AbstractECCS-0802109M. Raymer, University of Oregon EugeneObjective: To advance the field of quantum-optical information technology, this program explores methods for creating entangled photons pairs by spontaneous four-wave mixing in small-core optical fibers. This offers advantages, including creating photons that are well mode matched for low-loss fiber transmission. The work will be carried out by a collaboration of the Raymer group at the University of Oregon, the McKinstrie group at Bell Labs, and the Radic group at UC San Diego. Intellectual Merit: They will use parametric interactions in highly nonlinear fibers and photonic-crystal fiber to enable several basic capabilities: 1) pair-photon generation in fiber with controlled degree of spectral correlation or entanglement, 2) frequency conversion (translation) of quantum states of photons and modes in fiber while maintaining spectral or entanglement properties, 3) generation of amplitude-entangled fields of modes in fiber, and 4) linear coupling of signals at different carrier frequencies through nonlinear Bragg scattering.Broader impacts: Wavelength agility of optical signals plays an important role in modern communication systems. Quantum frequency conversion would have at least two uses: 1) to enable wavelength-division multiplexing of quantum signals, including those used for quantum cryptographic key distribution, and 2) to provide a means to manipulate entangled photons between many channels for the purpose of quantum computation. The project brings together quantum opticians with optical device scientists at other institutions, providing the opportunity for PhD students to spend time interacting with diverse scientists and benefiting from their facilities and expertise. Nonlinear optics offers excellent opportunities to integrate research with science education.

摘要ECCS-0802109M。俄勒冈大学雷默尤金目的：为了推动量子光信息技术领域的发展，该项目探索了在小芯光纤中通过自发四波混频产生纠缠光子对的方法。这提供了优势，包括产生模式匹配良好的光子，以实现低损耗光纤传输。这项工作将由俄勒冈大学的雷默小组、贝尔实验室的麦金斯特里小组和加州大学圣地亚哥分校的拉迪克小组合作进行。智能优点：它们将利用高度非线性光纤和光子晶体光纤中的参数相互作用来实现几种基本能力：1)在光谱相关或纠缠程度可控的光纤中产生双光子；2)在保持光谱或纠缠特性的同时，对光纤中光子和模式的量子态进行频率转换(平移)；3)在光纤中产生幅度纠缠场；以及4)通过非线性布拉格散射使不同载波频率的信号线性耦合。量子频率转换至少有两个用途：1)实现量子信号的波分复用，包括用于量子密钥分发的信号；2)为量子计算提供一种在多个通道之间操纵纠缠光子的方法。该项目将量子光学专家与其他机构的光学设备科学家聚集在一起，为博士生提供了与不同科学家互动的机会，并受益于他们的设施和专业知识。非线性光学提供了将研究与科学教育相结合的绝佳机会。
