Quantum nonlinear optics for experimental investigations of advanced quantum technologies and fundamental physics

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，这要归功于量子计算、激光物理和非线性材料方面的重大突破。 在这个提议中，我们描述了一个研究计划，它将非线性光学实验室中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。在第一批研究中，我们专注于成形激光脉冲技术，其中光脉冲中的不同颜色可以被结构化或组织化。 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。 我们建议将我们的发明“啁啾脉冲干涉仪”，一种新的干涉仪，这是强大的对色散，成为一个非侵入性的，高分辨率的3D光学成像原型。 我们还提出了利用非线性光学研究理论预测的量子相对论效应的量子模拟。 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局域性程度进行实验测试。 这些三胞胎将被运出实验室，并使用直接的视线光学链路发送到600米外的三个独立的接收站。在这些站的测量结果的相关性预测排除了一个大类的描述世界如何运作，最多有两个粒子的非局域性。这些实验将由本科生，研究生和博士后水平的研究人员进行。 该提案要求为他们的工资、差旅、设备和与出版结果有关的费用提供资金。 加拿大将直接受益于对这些研究人员的培训以及他们在培训期间开发的新技术。

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.
