The requested equipment supports the establishment of a new Quantum Nanophotonics Lab at Queen's University, which continues and builds on a successful and inclusive research program began at the Niels Bohr Institute. Our goal is to build quantum nonlinear optical effects photon-by-photon. To do so, we develop novel nanophotonic systems that enable us to perform challenging quantum optical measurements, advancing scientific knowledge of fundamental quantum light-matter interactions and opening pathways to efficient all-optical control of quantum photonic states. Our research is at the forefront of a rapidly growing international quantum community; rapidly re-establishing our lab in Canada, with support of the requested equipment, is crucial to maintaining this pole position and ensuring the success of the diverse group of scientists that work therein. We request funds for: i. two tunable narrowband lasers to act as sources of ultra-coherent photons and which can be scanned across the whole wavelength range of our quantum emitters; and ii. a high-finesse wavemeter to precisely determine the wavelengths of the photons, which enables active locking and stabilization of the laser outputs. Altogether, this system acts as source of independently tunable signal and control photons, capable of addressing any of our quantum emitters and mapping out the spectral response of each nonlinear interaction. This first-of-its-kind laser system at Queen's is not only integral to our research, but will facilitate collaborative research and development projects within the University and across Canada over the next decade and more. Though young, our research program has already trained a diverse and successful set of young scientists. In three years at the Niels Bohr Institute, 15 HQPs at all levels have worked within this program; all have gone on to either higher level academic positions, including one tenured position in France, or to high-impact positions in industry. Over half of the graduate or post-graduate HQPs have been women or from other under-represented groups, a testament to our active commitment to an inclusive environment. Though only established at Queen's three months ago, our group already contains 4 HQPs and is rapidly expanding. The timely acquisition of the applied-for laser system is critical to their training in a highly in demand skill-set the operation of quantum photonic equipment, advanced nanophotonic design and characterization, and deep knowledge of quantum theory and therefore to their future success in academia or the growing Canadian quantum technology industry.

所要求的设备支持在女王大学建立一个新的量子纳米光子学实验室，该实验室继续并建立在尼尔斯玻尔研究所开始的成功且包容性的研究项目的基础上。 我们的目标是逐个光子地构建量子非线性光学效应。为此，我们开发了新颖的纳米光子系统，使我们能够执行具有挑战性的量子光学测量，推进基本量子光与物质相互作用的科学知识，并为量子光子态的有效全光学控制开辟途径。我们的研究处于快速发展的国际量子界的前沿；在所需设备的支持下，在加拿大迅速重建我们的实验室，对于保持这一领先地位并确保在其中工作的多元化科学家群体的成功至关重要。 我们请求资金用于：两个可调谐窄带激光器作为超相干光子源，可以在我们的量子发射器的整个波长范围内进行扫描； ii.高精度波长计可精确确定光子的波长，从而实现激光输出的主动锁定和稳定。 总而言之，该系统充当独立可调信号和控制光子的来源，能够寻址我们的任何量子发射器并绘制出每个非线性相互作用的光谱响应。女王大学的这一首创激光系统不仅是我们研究的组成部分，还将在未来十年或更长时间内促进大学内部和加拿大各地的合作研究和开发项目。 尽管我们的研究项目还很年轻，但它已经培养了一批多元化且成功的年轻科学家。 在尼尔斯玻尔研究所的三年里，15 名各级 HQP 参与了该项目；所有人都获得了更高级别的学术职位，包括在法国的一项终身职位，或者在工业界担任高影响力的职位。 超过一半的毕业生或研究生 HQP 是女性或来自其他代表性不足的群体，这证明了我们对包容性环境的积极承诺。 虽然我们的小组仅在三个月前在女王大学成立，但已经拥有 4 个总部，并且正在迅速扩张。 及时获得所应用的激光系统对于他们接受急需的技能组合培训至关重要，包括量子光子设备的操作、先进的纳米光子设计和表征以及量子理论的深入知识，因此对于他们未来在学术界的成功至关重要或不断发展的加拿大量子技术产业。
