Quantum and nonlinear optics are two of the most exciting fields of physics today thanks to critical breakthroughs in quantum computing, laser physics, and nonlinear materials. In this proposal, we describe a research program which bring the normally disparate effects from the nonlinear optics laboratory to bear on quantum optical technologies. These ideas will have lasting technological impact in optical imaging and quantum state generation and fundamentally impact our understanding of quantum optics and quantum nonlocality. In the first stream of research, we focus on shaped laser pulse technology where the different colours in a light pulse can be structured or organized. We will use interactions with shaped laser pulses and single photons to compress the bandwidth of single photons so that they can be optimally coupled to single atoms or optical cavities. We propose to develop our invention 'chirped pulse interferometry', a new kind of interferometer which is robust against dispersion, into a noninvasive, high-resolution 3D optical imaging prototype. We also propose to investigate quantum simulation of a theoretically predicted quantum relativistic effect using nonlinear optics. In a second stream of research, we will perform an experimental test of the degree of quantum nonlocality which exists in nature using quantum correlated three-photon states from a nonlinear optical process called down-conversion. These triplets will be transported out of the lab and sent to three independent receiver stations 600m away using direct line-of-sight optical links. Correlations in the measurement results at these stations are predicted to rule out a large class of descriptions of how the world works which have at most two-particle nonlocality. These experiments will be carried out by undergraduate, graduate, and post-doctoral level researchers. This proposal requests funding for their salaries, travel, equipment, and costs associated with publishing results. Canada will directly benefit from the training of these researchers and the new technologies they develop during the course of this training.

由于量子计算、激光物理和非线性材料方面的关键突破，量子和非线性光学是当今物理学中最令人兴奋的两个领域。 在本提案中，我们描述了一项研究计划，该计划将非线性光学实验室通常不同的效应应用于量子光学技术。 这些想法将对光学成像和量子态生成产生持久的技术影响，并从根本上影响我们对量子光学和量子非定域性的理解。在第一个研究领域中，我们专注于整形激光脉冲技术，可以对光脉冲中的不同颜色进行结构化或组织。 我们将利用成形激光脉冲和单光子的相互作用来压缩单光子的带宽，以便它们可以最佳地耦合到单原子或光学腔。 我们建议将我们发明的“啁啾脉冲干涉仪”（一种对色散具有鲁棒性的新型干涉仪）开发成非侵入性高分辨率 3D 光学成像原型。 我们还建议研究使用非线性光学对理论上预测的量子相对论效应进行量子模拟。 在第二个研究流中，我们将使用来自称为下转换的非线性光学过程的量子相关三光子态，对自然界中存在的量子非定域性程度进行实验测试。 这些三元组将被运出实验室，并使用直接视距光链路发送到 600m 外的三个独立接收站。这些站测量结果的相关性预计将排除一大类关于世界如何运作的描述，这些描述最多具有两个粒子非局域性。这些实验将由本科生、研究生和博士后级别的研究人员进行。 该提案要求为他们的工资、差旅费、设备以及与发布结果相关的费用提供资金。 加拿大将直接受益于这些研究人员的培训以及他们在培训过程中开发的新技术。
