I request two spatial light modulators (SLMs), programmable optical beam shaping tools that can support our on-going project of building exciton-polariton quantum simulators (QS) as a next-generation high-performance computing platform. At the heart of the Information age, various formats of data are generated and handled as common audio or video signals, texts, and emails. And complex and big data are necessary to satisfy growing demands of information sharing in modern society. Moreover, the size of these data increases almost double up every year. Hence, high performance computing technologies are on high demand that aim to handle big sized data efficiently and to solve highly complicated computation problems controllably. Our group has been developing a photonic computing platform based on exciton-polaritons that can offer promising computational advantages from the system traits of nonlinearity and strong light-matter interactions through series of theoretical and experimental research activities for many years.   So far, we built prototypes of an exciton-polariton QS in fixed geometries using semiconductor material growth and device nanofabrication processing techniques. We characterized them optically to understand the basic operation principles, system dynamics, node connectivity and node-to-node coupling. Now we need to formulate practical applications to establish programmable exciton-polariton photonic QS. A critical technique for successful technological transition is reversible programmability and dynamical control of lasers in our optical setup because this allows us to study various types of situations readily.   We identify that the SLM is the best solution to our needs as a well-established optical technology to design laser beam profiles for defining a single site and for patterning multiple arrays of each site. Furthermore, we request two SLMs in order to engineer two opposite polarization states of lasers independently at the same time to represent binary states as a basic information unit. The high reflectivity of the proposed SLM models is desirable to control the laser power range widely so that we can exploit the full laser capacity and nonlinearity as a new functionality. Therefore, our selected SLM model can allow us to achieve all necessary technical specifications to create densely packed node arrays which are suitable for complex and large-scale problems. Since the SLM is regarded as state-of-the art quantum optical technologies to control lasers and quantum systems spatially and temporally, it is critical that students acquire hands-on experience in this advanced optical technology for their global leadership in quantum computing sectors. With the SLMs, our programmable exciton-polariton QS will pave ways to construct a powerful and competent photonic computing platform in a timely action with fast speed and compact footprints for favorable commercial implementation.

我请求两个空间光调制器（SLM），可编程光束整形工具，可以支持我们正在进行的构建激子-极化子量子模拟器（QS）作为下一代高性能计算平台的项目。在信息时代的核心，各种格式的数据被生成和处理为常见的音频或视频信号，文本和电子邮件。复杂的大数据是满足现代社会日益增长的信息共享需求所必需的。此外，这些数据的规模几乎每年增加一倍。因此，对高性能计算技术的需求很高，旨在有效地处理大数据并可控地解决高度复杂的计算问题。本课题组多年来通过一系列的理论和实验研究，开发了一个基于激子-极化激元的光子计算平台，该平台可以从系统的非线性和强的光-物质相互作用特性中提供有前途的计算优势。 到目前为止，我们使用半导体材料生长和器件纳米加工技术建立了固定几何形状的激子极化激元QS原型。我们的特点是他们的光学理解的基本工作原理，系统动力学，节点连接和节点到节点的耦合。现在，我们需要制定实际的应用程序，建立可编程激子-极化激元光子QS。成功的技术转型的一个关键技术是可逆的可编程性和动态控制的激光器在我们的光学设置，因为这使我们能够研究各种类型的情况很容易。 我们确定SLM是满足我们需求的最佳解决方案，因为它是一种成熟的光学技术，可以设计用于定义单个站点和每个站点的多个阵列的激光束轮廓。此外，我们要求两个SLM，以工程的两个相反的偏振态的激光在同一时间独立代表作为一个基本信息单元的二元状态。所提出的SLM模型的高反射率是期望的，以广泛地控制激光功率范围，使得我们可以利用全激光容量和非线性作为一个新的功能。因此，我们选择的SLM模型可以让我们实现所有必要的技术规格，以创建密集的节点阵列，适用于复杂和大规模的问题。由于SLM被认为是在空间和时间上控制激光器和量子系统的最先进的量子光学技术，因此学生在这种先进的光学技术方面获得实践经验对于他们在量子计算领域的全球领导地位至关重要。借助SLM，我们的可编程激子-极化子QS将为及时构建一个功能强大的光子计算平台铺平道路，该平台具有快速和紧凑的占地面积，有利于商业实施。
