QMPH: Modeling of a Photonic Crystal Hosting a Quantum Network Made of Single Spins in Quantum Dots that Interact via Single Photons

提案编号：0725514提案标题：QMHP：承载量子网络的光子晶体建模，该量子网络由通过单光子相互作用的量子点中的单自旋组成PI姓名： Schoenfeld，Winston V. PI机构：中央佛罗里达大学这个项目是一个面向设备的实验学家和量子建模者之间的合作。他们计划共同建立一个新的模型，以证明他们可以通过使用他们开创的新硬件方法来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，计算在较旧的简单类型的模型中错过的耦合效应，以便从他们过去所做的设备级工作转向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偏振和电子自旋的纠缠，即纳米腔中量子点中电子的自旋，纳米腔嵌入光子晶体中，光子晶体包含连接纳米腔的波导。智力优势研究人员将开发一个新的模拟模型，能够捕捉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一个增广的Jaynes-Cumming模型中，这是一个由偶极相互作用项增广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形式主义的主方程进行实际计算。更广泛的好处PI将使用他们的新模式作为教育工具。该工具将用于整个量子比特系统（电子-光子-电子）纠缠过程的实时可视化，以及每个量子比特状态演化的实时可视化（这使得可以探索量子网络内的量子信息流）。教育和推广计划的范围从博物馆展示和演示，到Partin小学和大学高中的定期K-12参与，到白求恩-库克曼（一所历史悠久的黑人大学）的本科生夏季研究机会，以及大学纳米科学技术中心的新活动。

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.
