Imagine hands covered in wide-meshed woolen mittens in winter compared to those protected by modern materials that keep the skin dry and warm and additionally charge your phone. This gives an analogy to how future technologies can profit from new so-called quantum materials that are currently at the forefront of research. These materials are capable of transmitting quantum effects into our macroscopic world, be it for new metrologies or devices used in photonics, electronics or telecommunication industries. To exploit such features however requires in-depth characterization which is greatly limited with current metrologies and calls for new developments. The proposed project will allow researchers from INRS-EMT and its industrial partner Quantum Valley Investments (QVI) - a think-tank developing quantum materials, to create such new metrologies. This requires the combination of conventional laboratory based ultrafast temporal resolution with short wavelength particles (photons and electrons). Fully accessing the interior of such quantum materials demands a combination of well controlled XUV/soft X-ray photons and ultrafast electron bunches. With the X-ray pulses the material's electrons will be characterized, while the electron bunches provide complementary lattice information. At the ALLS facility located in Varennes (Qc), both have been produced in the past and will be shaped within the current research proposal to meet the high requirements necessary for such new material characterization. An important component of this project will be the transfer of a metrology - a high flux harmonic source - to QVI's R&D facility in Waterloo (On). Once the metrologies are set, they will be applied and validated for studying dynamics in materials of high relevance to QVI. The proposed metrologies/instrumentations and the training of highly-qualified personnel will contribute to keep Canada at the forefront of the rapidly moving "quantum revolution", thereby enhancing its leading position across critical sectors that vitally require powerful quantum computation and metrology platforms, such as advanced environmental sensing, high-precision chemical analysis, and increased security protocols.

想象一下，与那些受到现代材料保护的手套相比，冬季用宽丝羊毛手套覆盖的手覆盖着，这些材料使皮肤干燥，温暖并另外为手机充电。这比较类似于未来技术如何从当前处于研究最前沿的新的所谓量子材料中获利。这些材料能够将量子效应传输到我们的宏观世界中，无论是用于光子学，电子或电信行业的新计量学或设备。但是，要利用此类功能需要深入的特征，这在当前的计量和呼吁新开发方面受到了很大的限制。拟议的项目将允许来自INRS-EMT及其工业合作伙伴量子谷投资（QVI）的研究人员 - 一种智慧开发的量子材料，以创建这种新的计量。这就需要将基于实验室的超快时间分辨率与短波长颗粒（光子和电子）组合在一起。完全进入此类量子材料的内部需要良好控制的XUV/软X射线光子和超快电子束的组合。使用X射线脉冲，将表征材料的电子，而电子束提供互补的晶格信息。在瓦伦尼斯（QC）的Alls设施中，两者都在过去生产，并将在当前的研究建议中塑造，以满足这种新材料表征所需的高要求。该项目的一个重要组成部分是将计量学（高通量谐波源）转移到滑铁卢（ON）的QVI的R＆D设施。设置计量学之后，将对它们应用和验证，以研究与QVI高相关材料的动力学。拟议的计量/仪器以及对高度合格的人员的培训将有助于使加拿大保持迅速移动的“量子革命”的最前沿，从而增强了其在关键领域的领先地位，这些领域具有强大的量子计算和计量平台，例如高级环境感应，高级化学化学分析和增强的安全协议。
