项目摘要

Quantum communication offers the tantalizing possibility of sending secure messages over long distances. However, developing materials that can act as the central information carriers, the "bits" in quantum communication, is difficult. One strategy for creating quantum bits, or "qubits", is to combine the quantum mechanical properties of light with molecules, or plasmonic nanoparticles. With support from the Macromolecular, Supramolecular and Nanochemistry and Chemical Theory, Models and Computational Methods Programs in the Division of Chemistry, Professor David Masiello of the University of Washington and Professor Randall Goldsmith of the University of Wisconsin Madison are developing ways to force repeated interaction between light and molecular or nanoparticle quantum emitters, enabling them to act as qubits. The research discoveries could have broad implications for emerging quantum-based technologies, including quantum computing and quantum communication. The project is also providing interdisciplinary training at the graduate and undergraduate levels at the intersection between optics, photonics, quantum information, and nanomaterial fields, as well as public outreach activities demonstrating the importance of photonics (the interaction of light and matter) and quantum information. Working with their students, Professors Masiello and Goldsmith create small disk-shaped structures called toroidal microresonators decorated with molecules or nanoparticles. Light injected into the disk undergoes total internal reflection, causing it to propagate almost endlessly around the periphery of the disk with very little loss. As it moves around the disk, it interacts with molecules or nanoparticles placed on its surface, enabling the structure to maintain strong coupling between a variety of molecular and nanomaterial quantum absorbers. The project, which contains a strong interplay between theory and experiment, focuses on production and manipulation of states that demonstrate Dicke superradiance. Characterization of new coupled states is achieved by microresonator photothermal spectroscopy and photoluminescence, with experimental observation being understood in the context of an underlying theory that describes the state evolution and relevant dissipation processes.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

量子通信提供了长途发送安全消息的诱人可能性。但是，开发可以充当中央信息载体的材料，量子通信中的“位”很困难。创建量子位或“ Qubits”的一种策略是将光的量子机械性能与分子或等离子纳米颗粒相结合。在化学部的大分子，超分子和纳米化学和化学理论的支持下，模型和计算方法计划，华盛顿大学的戴维·马西洛教授和威斯康星大学麦迪逊大学的兰德尔·戈德史密斯教授正在开发如何在光线和分子量子量子上反复互动，以供他们互动，以应对态度，以供他们供应。研究发现可能对新兴的基于量子的技术具有广泛的影响，包括量子计算和量子通信。该项目还在光学，光子学，量子信息和纳米材料领域之间的交叉点提供跨学科培训，并在研究生和本科水平上提供跨学科的培训，以及展示光子学（光与物质的相互作用）和量子信息的重要性的公共外展活动。与学生合作，Masiello和Goldsmith教授创建了用分子或纳米颗粒装饰的小磁盘形结构，称为环形微孔子。注射到磁盘中的光经历了总内部反射，导致其几乎无休止地在磁盘周围传播，但损失很小。当它围绕磁盘移动时，它与放置在其表面上的分子或纳米颗粒相互作用，从而使结构能够在各种分子和纳米材料量子吸收器之间保持强耦合。该项目包含理论与实验之间的强烈相互作用，重点是展示迪克超赞的国家的生产和操纵。新耦合状态的表征是通过微孔子光热光谱和光致发光来实现的，实验观察是在描述国家进化和相关耗散过程的基本理论的背景下来理解的。该奖项反映了NSF的法定任务，并通过评估智能构成了基金会的范围，并通过评估了基金会的范围和广泛的影响。
