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项目探讨了线性光学元件实施量子信息处理（QIP）的新方法。一般目标是学习如何在已知的纯状态下创建单光子波数据包，以通过线性光学系统以受控方式转换其空间和极化状态，并使用光子子集的条件测量来驱动概率量子逻辑门操作。该项目将解决主题的进展：（1）受控的光子量子量子产生； （2）单量器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）光纤中光子的光子和量子门。这项研究将超出量子信息领域的更大影响。该项目通过光学设备科学家汇集了量子眼镜师。这项合作已经在设备研究中产生了新的结果？电螺旋硅波导，它可能为经典和量子信息处理提供了强大的平台。本项目与英国的研究人员合作，为美国博士学生提供了在牛津大学和南安普敦大学度过时光的机会，进行研究并从其设施和专业知识中受益。 NSF国际计划有助于实现这一目标。
