Development of novel quantum materials and their ultrafast characterization using advanced near- and mid-infrared spectroscopy

由于其独特的性质，量子材料是突破性研究的温床，提供了许多科学和技术机会。我们的工业合作伙伴QVI/IPL和Axis Photonique希望利用QM科学的最新进展，为量子计算和量子模拟应用开发新的量子技术。他们对真空效应的控制特别感兴趣，真空效应的起源在于电磁真空场的涨落和光-物质耦合，这将使其在量子信息、纳米和光电子学、探测器和传感器方面的应用成为可能。我们的工业伙伴希望加强他们在量子体系的合成/生长和分析方面的能力。这将通过拟议的联盟项目实现，(I)发展关于制备和表征新的异质结构或功能化材料的专门知识，以及(Ii)支持开发利用二维相干光谱学和高次谐波光谱学探测其动力学的测量技术。该项目将开发包括功能化有机半导体在内的新的异质结构，其超快声子动力学将通过先进的超快光谱和高次谐波光谱来研究。该项目将使QVI/IPL能够为包括量子信息科学在内的许多应用设计量子过程。这还将导致Axis Photonique的一种新产品，预计该产品将被证明对QMS的表征至关重要，这两项都将是量子技术领域的重要进展。

Due to their unique properties, quantum materials (QMs) are a hotbed for ground-breaking research, offering many scientific and technological opportunities. Our industrial partners, QVI/IPL and Axis Photonique, would like to take advantage of the latest advances in QM science to develop new quantum technologies for applications in quantum computing and quantum simulations. They are especially interested in the control of vacuum effects, whose origin lies in the fluctuations of the electromagnetic vacuum field and light-matter coupling, which will enable applications in quantum information, nano- and optoelectronics, detectors and sensors.Our industrial partners wish to strengthen their capabilities on the synthesis/growth of QMs and their analysis. This will be realized through the proposed Alliance project, (i) by developing expertise on preparing and characterizing new heterostructural or functionalized materials, and (ii) by supporting the development of measurement techniques to probe their dynamics, using two-dimensional coherent spectroscopy and high-order harmonic spectroscopy. The proposed project will develop new QMs (heterostructures), including functionalized organic semiconductors, whose ultrafast phonon dynamics will be studied by advanced ultrafast spectroscopy and high-harmonic spectroscopy. The project will enable QVI/IPL to design quantum processes for many applications, including quantum information science. It will also result in a new product for Axis Photonique that is expected to prove crucial for the characterization of QMs, both of which will be important advances in the field of quantum technologies.
