0334590Raymer这个美国-英国论文增强项目支持博士学位。俄勒冈大学的学生布赖恩·史密斯（Brian Smith）在俄勒冈大学的迈克尔·雷默（Michael Raymer）和牛津大学的伊恩·沃尔姆斯利（Ian Walmsley）的指导下进行论文研究。 它为俄勒冈大学的 ITR（信息技术研究）奖增添了一个国际维度，该奖旨在工程控制的单光子源并利用它们开发用于量子信息处理（QIP）的全光学手段。 两个粒子状态的量子纠缠有可能成为一类新技术——量子信息处理的基础。 QIP包括量子密码密钥分发、量子通信和量子计算。 光学光场量子纠缠的产生和操纵是进一步发展实用QIP的关键技术。这项工作的目标是开发实用技术，以实现对产生单光子或光子对的时空波包模式的高度控制。 为了实现 QIP 目标，牛津和南安普顿小组将设计和制造图案晶体，然后在俄勒冈和牛津实验室进行测试和使用。 学生将为设计和制造方面做出贡献，并获得牛津小组开发的技术的经验。这项研究将推动新型非线性光学材料的开发，这些材料可用于倍增光、电信和经典光学计算等一系列应用。 用于表征光的空间相干性研究的新技术将得到开发，并可能在其他光学领域得到应用。

0334590RaymerThis U.S.-U.K. dissertation enhancement project supports a Ph.D. student, Brian Smith of the University of Oregon, to pursue thesis research under the guidance of Michael Raymer, University of Oregon and Ian Walmsley, University of Oxford. It adds an international dimension to the University of Oregon's ITR (Information Technology Research) award aimed at engineering controlled single-photon sources and using them to develop all-optical means for Quantum Information Processing (QIP). Quantum entanglement of the states of two particles carries potential to serve as a basis for a new class of technology - Quantum Information Processing. QIP includes quantum cryptographic key distribution, quantum communication and quantum computation. Generation and manipulation of quantum entanglement of optical light fields are key techniques in the further development of practical QIP. The objective of this work is to develop practical technologies for achieving a high degree of control over the space-time wave-packet modes in which single photons or pairs of photons are created. To achieve the QIP goals, the Oxford and Southampton groups will design and fabricate patterned crystals that then will be tested and used at the Oregon and Oxford labs. The student will contribute to the design and fabrication aspects and gain experience with the technology developed by the Oxford group.This research will advance the development of new nonlinear optical materials that are useful for a range of applications such as doubling of light, telecommunications and classical optical computing. New techniques for characterizing the spatial coherence studies of light will be developed and may have applications in other fields of optics.
