Proposal Number: 0725514Proposal Title: QMHP: Modeling of a Photonic Crystal Hosting a Quantum Network Made of Single Spins in Quantum Dots that Interact via Single PhotonsPI Name: Schoenfeld, Winston V. PI Institution: University of Central FloridaObjectiveThis project is a collaboration between a device oriented experimentalist and a quantum modeler. Together they plan to build a new model to use, in proving that they can achieve quantum teleportation and secure quantum communication by using a new hardware approach that they have pioneered. They will need a new kind of model, computing coupling effects which have been missed in older simpler types of model, in order to go from the device-level work they have done in the past, to the systems-level challengeof designing and simulating an entire quantum communications system. The new hardware approach involves the entanglement of photon polarization and electron spin, for the spin of an electron in a quantum dot inside a nanocavity, with nanocavities embedded in a photonic crystal containing waveguides that connect the nanocavities.Intellectual MeritThe PIs will develop a new simulation model capable of capturing the entangled behavior of the new type of quantum network system they are proposing to study. To build this model, they will first use partial wave and FTDT methods to calculate the spectrum of photons available, coupling strengths and other parameters. Next, they will insert these inputs and parameters into an augmented Jaynes-Cumming model, a quantum field theory Hamiltonian augmented by a dipole interaction term; this extra term will require that they perform a dynamic simulation (instead of just calculating a static equilibrium), and use a master equation based on the Wigner formalism for the actual computations. Broader BenefitsThe PIs will use their new model as a tool in education. The tool will be used both in real-time visualization of the process of entanglement of the entire system of qubits(electron-photon-electron), and in real-time visualization of the evolution of the state of each individual qubit (which makes it possible to explore the flow of quantum information within the quantum network). The plans for education and outreach range from museum demonstration and presentation, to regular K-12 participation at Partin Elementary School and University High School, to summer research opportunities for undergraduates at Bethune-Cookman (an historically black college), and to new activities at the universities NanoScience Technology Center.

提案编号：0725514提案标题：QMHP：建立由量子点中的单自旋组成的量子网络的光子晶体建模PI名称：Schoenfeld，Winston V.PI机构：中央佛罗里达大学目标该项目是一名面向设备的实验者和一名量子建模师之间的合作。他们计划共同建立一个新的模型来使用，以证明他们可以通过使用他们首创的新硬件方法实现量子隐形传态和安全的量子通信。他们将需要一种新的模型，计算在旧的更简单类型的模型中忽略的耦合效应，以便从他们过去所做的设备级工作，到设计和模拟整个量子通信系统的系统级挑战。新的硬件方法涉及光子极化和电子自旋的纠缠，对于位于纳米腔内的量子点中的电子的自旋，将纳米腔嵌入包含连接纳米腔的波导的光子晶体中。智力价值PI将开发一种新的模拟模型，能够捕获他们提议研究的新型量子网络系统的纠缠行为。为了建立这个模型，他们将首先使用分波和FTDT方法来计算可用光子的光谱、耦合强度和其他参数。接下来，他们将把这些输入和参数插入到增广的Jaynes-Cumming模型中，这是一个由偶极相互作用项扩充的量子场论哈密顿量；这个额外的项将要求他们执行动态模拟(而不仅仅是计算静态平衡)，并使用基于Wigner形式的主方程进行实际计算。更广泛的好处私人投资机构将把他们的新模式作为教育的工具。该工具将用于实时可视化整个量子比特系统(电子-光子-电子)的纠缠过程，以及实时可视化每个量子比特的状态演变(这使得探索量子网络中的量子信息流成为可能)。教育和外展计划的范围从博物馆演示和展示，到帕廷小学和大学高中定期参加K-12课程，到白求恩-库克曼大学(一所历史上的黑人学院)为本科生提供的暑期研究机会，以及在大学纳米科学技术中心的新活动。
