Arguably one of the greatest feats of ultrafast science up until now has been the development of tools which enable access to the elementary dynamics of the fundamental degrees of freedom of matter. In particular, the ability to measure time evolution of fields has opened a unique window into the world of condensed matter physics, where a formation of quasiparticles, collective modes and dynamics of their correlations can be observed on the fundamental timescales of the respective processes. This progress has provided a leap in our microscopic understanding of many-body interactions and motivated the development of novel applications and devices. Owing to their intrinsically quantum-mechanical nature, the interplay of various fundamental degrees of freedom of a solid can be understood more directly if one is able to access quantum instead of classical system observables. Furthermore, the capability of a truly quantum field-resolved detection would enable direct observation of the evolution of quantum correlations in the time domain. Such ability is poised to seed a new era of quantum spectroscopy of light-matter interaction. In this proposal, we elaborate our long-term plan toward the development of a novel experimental approach to ultrafast quantum electrodynamics which also seeks to harness this quantumness for cutting edge applications. We outline broad research goals as intermediate steps toward the pursuit of this main idea. To this end, we subdivide the activities into three research threads. In the first, we explore novel sources of ultrafast nonclassical light. The second develops new time-domain detection methodologies for field-resolved sensing of quantum light and, finally, in the third thread we make first steps toward quantum spectroscopy of matter and light-matter coupling. Along the way, we are also seeking for new cutting edge applications which our novel approach entails. We believe that the efficient path for research is to synergistically combine fundamental studies with the development of precision instrumentation and novel measurement techniques at the world-class level. As designed, our Program is motivated by both advancing the fundamental research in physics as well as the development of high-tech applications in the field of photonics. Within this framework, we believe that our Program offers a well-integrated, diverse and engaging platform for training future generations of highly qualified professionals in industry as well as academia.

可以说，到目前为止，超快科学的最伟大壮举之一是开发工具，可以访问基本物质自由度的基本动态。特别是，测量田地时间演变的能力为凝聚态物理学的世界打开了一个独特的窗口，在这些窗口中，可以在相应过程的基本时间表上观察到准粒子，集体模式和相关性的形成。这一进步为我们对多体相互作用的理解提供了飞跃，并激发了新型应用和设备的发展。由于其本质上的量子力学性质，如果能够访问量子而不是经典的系统可观察物，则可以更直接地理解各种基本自由度的相互作用。此外，真正的量子场分辨检测的能力将能够直接观察到时域中量子相关的演变。这种能力有助于播种光 - 物质相互作用的量子光谱的新时代。在此提案中，我们阐述了我们的长期计划，以开发一种新型的超快量子电动力学方法，该方法也试图利用这种量子来实现最前沿应用。我们将广泛的研究目标概述为追求这一主要思想的中间步骤。为此，我们将活动细分为三个研究线程。首先，我们探索了超快非古老光的新颖来源。第二个开发了用于量子光的现场分辨传感的新的时间域检测方法，最后，在第三个线程中，我们迈出了迈向物质和光 - 物质耦合的量子光谱的第一步。在此过程中，我们还在寻求新型方法需要的新的尖端应用。我们认为，研究的有效途径是将基本研究与精确仪器和新颖的测量技术的发展结合起来。按照设计，我们的计划是由推进物理学的基本研究以及光子学领域高科技应用的开发所激发的。在此框架内，我们认为我们的计划为培训子孙后代的行业和学术界提供了一个整合，多样和引人入胜的平台。
