Dissipative mode theories and reservoir engineering in quantum nanophotonics

光子学是产生、控制和探测光的基本粒子（光子）的科学。限制在微米尺度的光（光纤）已经彻底改变了信息技术。然而，随着器件和光学结构的不断缩小，我们已经开始进入一个新的光学技术领域，称为“纳米光子学”，其中光在纳米（nm）尺度上的行为，以及纳米尺度物体（光子纳米结构）与光的相互作用在性质上是不同的。光子纳米结构允许在基本量子力学水平上对物质和光物质相互作用进行前所未有的控制和表征，从而开启了一系列新技术，包括量子光源和量子传感器。我的研究小组在纳米光子学和量子光学的理论理解方面处于世界领先地位。我们开发光-物质相互作用的创新模型和模拟，以解释新数据，预测新机制并实现新的量子设备。已经建立了一个强大的合作网络，涉及加拿大、美国、德国、丹麦、新西兰和日本的团体。该提案介绍了耗散模式（开放腔模式和纳米等离子体）和水库工程的理论和应用的雄心勃勃的研究计划，以研究和利用量子纳米光子学和量子电路中的光物质相互作用。这项工作是由开放系统量子光学中的深层基础物理问题驱动的（例如，如何在任意结构中对光进行光调制，具有任意相互作用强度和任意时间依赖控制），以及纳米光子混合系统中的新兴应用。我们的工作对基础科学发现很重要，并应用于下一代量子和纳米光子技术。研究主题将研究广泛的光子纳米结构，如半导体量子点，纳米线波导，金属纳米谐振器，混合电介质-金属系统和机械谐振器，以无与伦比的控制来操纵量子光-物质相互作用。这种控制将通过油藏工程来辅助，包括光学控制（激光）、相干反馈和混合量子系统。这项发现补助金的成果将通过以下方式产生广泛而重大的影响：（i）开发强大而有效的模型来描述固态纳米结构和具有损耗的开放腔中的开放系统量子光学，（ii）与领先的理论小组合作，以帮助开发最准确和有效的模型，（iii）与领先的实验小组合作，以测试我们的理论并解释他们的数据，及（iv）为对加拿大经济重要的光子技术领域的实习研究人员提供充满活力和激励的培训经验。该研究计划将是国际领先的，并将在纳米光子学的量子理论中引入新的篇章。

Photonics is the science of generating, controlling, and detecting the fundamental particles of light (photons). Light confined to the micron scale (optical fibers) has revolutionized information technology. However, as devices and optical structures continue to shrink, we have started to enter a new realm of optical technology termed "nanophotonics", wherein the behavior of light on the nanometre (nm) scale, and of the interaction of nm-scale objects (photonic nanostructures) with light is qualitatively different. Photonic nanostructures allow unprecedented control and characterization of matter and light-matter interactions at the fundamental quantum mechanics level, unlocking new set of technologies, including quantum light sources and quantum sensors. My research group is a world leader in the theoretical understanding of nanophotonics and quantum optics. We develop innovative models and simulations of light-matter interactions to explain new data, predict new regimes and realize new quantum devices. A strong network of collaborations has been put in place, involving groups in Canada, USA, Germany, Denmark, New Zealand and Japan. This proposal introduces an ambitious research program on the theory and application of dissipative modes (open cavity modes and nanoplasmonics) and reservoir engineering, to study and exploit light-matter interactions in quantum nanophotonics and quantum circuits. The work is driven by deep fundamental physics problems in open system quantum optics (e.g., how to quantize light in arbitrary structures, with arbitrary interaction strengths and arbitrary time-dependent control), as well as emerging applications in nanophotonic hybrid systems. Our work is important for fundamental science discoveries and has applications for next-generation quantum-and nano-photonic technologies. The research themes will study a wide range of photonic nanostructures such as semiconductor quantum dots, nanowire waveguides, metal nanoresonators, hybrid dielectric-metal systems, and mechanical resonators to manipulate quantum light-matter interactions with unparalleled control. This control will be aided through reservoir engineering, involving optical control (lasers), coherent feedback, and hybrid quantum systems. The outcomes of this discovery grant will find broad and significant impact through: (i) the development of powerful and efficient models to describe open-system quantum optics in solid state nanostructures and open cavities with loss, (ii) collaboration with leading theory groups to help develop the most accurate and efficient models, (iii) collaboration with leading experimental groups to test our theories and to explain their data, and (iv) providing a vigorous and stimulating training experience for trainee researchers in technological photonics areas that are important to the Canadian economy. The research program will be internationally leading and will introduce a new chapter in the quantum theory of nanophoptonics.
