Ultra-coherent Lasers for the Exploration of Quantum Photonic Nonlinearities

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·玻尔研究所开始的一个成功和包容的研究计划的基础上。我们的目标是逐个光子地建立量子非线性光学效应。为此，我们开发了新的纳米光子系统，使我们能够执行具有挑战性的量子光学测量，促进基本量子光与物质相互作用的科学知识，并开辟有效的量子光子态全光学控制的途径。我们的研究处于迅速发展的国际量子社区的前沿；在所需设备的支持下，迅速在加拿大重新建立我们的实验室，对于保持这一领先地位并确保在其中工作的不同科学家群体的成功至关重要。 我们请求资金用于：i.两个可调谐的窄带激光器，作为超相干光子源，可以扫描我们量子发射器的整个波长范围；以及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，这个系统充当了独立可调的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。皇后学院的这一首创激光系统不仅是我们研究不可或缺的一部分，而且将在未来十年和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。 我们的研究项目虽然年轻，但已经培养了一批多样化和成功的年轻科学家。在尼尔斯·玻尔研究所的三年时间里，有15名各级HQP在这个项目内工作；所有人要么进入了更高级别的学术职位，包括在法国的一个终身职位，要么进入了行业中有影响力的职位。超过一半的毕业生或研究生是妇女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。虽然三个月前才在皇后学院成立，但我们的团队已经拥有4个总部基地，并且正在迅速扩大。及时获得所申请的激光系统对于他们在高需求技能集方面的培训至关重要，这些技能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深厚的量子理论知识，因此对于他们未来在学术界或不断增长的加拿大量子技术行业的成功至关重要。

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.
