Tunable pulse-shapers for the exploration of dynamic photon-photon interactions

所要求的设备支持女王大学新的量子纳米光子学实验室的发展。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。我们的研究处于快速增长的国际量子社区的前沿，所需的设备对于保持这一极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。我们要求为两个任意脉冲发生器提供资金，这些脉冲发生器能够将我们的连续激光转变为宽度可达三个数量级的可广泛调谐的脉冲来源。拥有两个这样的独立脉冲源，可以对不同的光子进行独立调谐的多光子实验，使人们能够了解通过单个量子发射器调节的基本未知的少光子量子非线性动力学；反过来，塑造每个脉冲的能力又赋予了塑造动力学、操纵和增强巨型光子-光子相互作用的能力，这是其他平台根本不可能实现的。这是皇后学院首创的激光系统，不仅是我们研究不可或缺的一部分，而且将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。在过去的两年里，我们的团队在皇后学院成立以来，已经培训了20多名各级HQP；所有人都进入了更高级别的学术职位，包括在法国的一个终身职位，或者进入了工业领域的高影响力职位。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。应用于任意脉冲发生器的及时获取对于他们在高需求技能集-量子光子设备的操作、先进的纳米光子设计和表征以及对量子理论的深厚知识-方面的培训至关重要，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生态系统中的成功至关重要。

The requested equipment supports the growth of a the new Quantum Nanophotonics Lab at Queen's University. 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 and 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 two arbitrary pulse generators capable of turning our continuous lasers into sources of widely tunable pulses whose widths can span three-orders of magnitude. Having two such independent pulse sources enables multi-photon experiments with independent tuning of the different photons, shining a light on largely unexplored dynamics of few-photon quantum nonlinearities mediated via individual quantum emitters; the ability to shape each pulse, in turn, confers the ability to shape the dynamics, manipulating and enhancing giant photon-photon interactions that are simply not possible with other platforms. 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. Though young, our research program has already trained a diverse and successful set of young scientists. In the past 2 years, since its establishment at Queen's, our group has trained over 20 HQP across all levels; 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 HQP have been women or from other under-represented groups, a testament to our active commitment to an inclusive environment. The timely acquisition of the applied-for arbitrary pulsed generators 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 ecosystem.
