项目摘要

This PIF project explores novel approaches to implementing quantum information processing (QIP) by linear optics. The general goal is to learn how to create single-photon wave packets in known pure states, to propagate them through linear-optical systems that transform their spatial and polarization states in controlled ways, and to use conditional measurement of a subset of the photons to drive probabilistic quantum logic gate operations. The project will address a progression of topics: (1) Controlled photonic qubit generation; (2) Transverse orbital photon states for single-qubit encoding; (3) Orbital cluster states and orbital fusion gates for photons; (4) Orbital states and qubit gates for photons in optical fiber. The research will have broader impact beyond the field of quantum information. The project brings together quantum opticians with optical device scientists. This collaboration has already yielded new results in device research?electrically poled silica waveguides, which may provide a powerful platform for classical as well as quantum information processing. The present project is collaborative with researchers in the United Kingdom, providing the opportunity for U.S. PhD students to spend time at Oxford and Southampton universities, carrying out research and benefiting from their facilities and expertise. NSF International Programs has contributed to making this possible.

这个PIF项目探索了通过线性光学实现量子信息处理（QIP）的新方法。总体目标是学习如何在已知纯态中创建单光子波包，将它们传播通过以受控方式转换其空间和偏振状态的线性光学系统，并使用光子子集的条件测量来驱动概率量子逻辑门操作。该项目将解决一系列主题：（1）受控光子量子比特生成;（2）单量子比特编码的横向轨道光子状态;（3）光子的轨道簇状态和轨道融合门;（4）光纤中光子的轨道状态和量子比特门。这项研究将在量子信息领域之外产生更广泛的影响。该项目汇集了量子光学家和光学设备科学家。这种合作已经在设备研究方面取得了新的成果？电极化的二氧化硅波导，这可以为经典以及量子信息处理提供强大的平台。本项目与联合王国的研究人员合作，为美国博士生提供在牛津大学和南安普顿大学学习的机会，开展研究并从他们的设施和专业知识中受益。NSF国际项目为实现这一目标做出了贡献。
