Breakthrough technological and scientific advances are driven by our ability to control nature. Harnessing subtle quantum mechanical features of light and matter will lead to powerful new technologies with broad impact in how we process and share information. Optical systems feature prominently in these emerging quantum technologies as they are unparalleled in their ability to exchange quantum information over large distances. This Discovery Grant application requests funding for a research program in optical quantum information science focusing on three interrelated challenges: next-generation quantum light sources, ultrafast quantum optics, and quantum foundational experiments. ******Quantum light is the foundation for quantum optical technologies. As just one example, ultra-secure quantum cryptography can be achieved by exchanging single-photon polarization states. We propose to develop quantum light sources, based on artificial atoms that will become the new standard for single-, and entangled-photons. We propose to exploit fast laser pulses and nonlinear optical interactions to manipulate the temporal properties of single photons in the ultrafast limit. We will develop new quantum pulse characterization tools and interferometry in this regime, leading to full control over the single-photon waveform on the fastest of timescales. We will develop new methods for determining quantum states, quantum measurements, and the underlying quantum causal structure in experiments. We propose to measure trajectories of interfering photons using weak measurements and infer the Quantum Potential giving rise to bright and dark regions of interference pattern.******The research streams described in this proposal complement each other. Advancing the frontiers of quantum emitters and ultrafast quantum optics enable more demanding technologies and foundational experiments, while advances in quantum foundations establish stringent benchmarks, challenging us to expand the limits of sources and control. The experimental advances and theoretical understanding developed through this research program will have lasting impact through our ability to harness quantum states of light and discover the resources for tomorrow's quantum applications. These experiments will be carried out by undergraduate, graduate, and post-doctoral researchers. This proposal requests funding for their salaries, travel, experiments, and publications costs. Canada will directly benefit from the training of these researchers and new technologies they developed during the course of this training.***********

突破性的技术和科学进步是由我们控制自然的能力驱动的。 利用光线和物质的微妙的量子机械特征将导致强大的新技术对我们处理和共享信息的方式产生广泛的影响。 光学系统在这些新兴的量子技术中突出特征，因为它们在大距离内交换量子信息的能力是无与伦比的。 该发现赠款应用程序要求为光学量子信息科学研究计划提供资金，重点介绍了三个相互关联的挑战：下一代量子光源，超快量子光学元件和量子基础实验。 ******量子光是量子光学技术的基础。 仅仅一个例子，可以通过交换单光子极化状态来实现超安全量子加密。 我们建议基于人工原子开发量子光源，这些原子将成为单个和纠缠量的新标准。 我们建议利用快速激光脉冲和非线性光学相互作用，以在超快极限下操纵单个光子的时间特性。 我们将在此制度中开发新的量子脉冲特征工具和干涉法，从而完全控制最快的时间尺度上的单光子波形。 我们将开发用于确定实验中量子状态，量子测量和潜在量子因果结构的新方法。 我们建议使用弱测量值测量干扰光子的轨迹，并推断量子电位引起干扰模式的明亮和黑暗区域。******该提案中描述的研究流相互补充。 推进量子发射器和超快量子光学器件的前沿，可以实现更多苛刻的技术和基础实验，而量子基础的进步则建立了严格的基准，从而挑战了我们扩大源和控制的极限。通过该研究计划发展的实验进步和理论理解将通过我们利用光量子状态并发现明天的量子应用的资源来产生持久的影响。 这些实验将由本科，研究生和博士后研究人员进行。该提案要求提供薪水，旅行，实验和出版物费用的资金。加拿大将直接受益于他们在培训期间开发的这些研究人员和新技术的培训。************************************************
