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.
