In recent years, the notion of ‘Quantum Materials’ has emerged as a powerful unifying concept across diverse fields of science and engineering, from condensed-matter and coldatom physics to materials science and quantum computing. Beyond traditional quantum materials such as unconventional superconductors, heavy fermions, and multiferroics, the field has significantly expanded to encompass topological quantum matter, two-dimensional materials and their van der Waals heterostructures, Moir materials, Floquet time crystals, as well as materials and devices for quantum computation with Majorana fermions. In this Roadmap collection we aim to capture a snapshot of the most recent developments in the field, and to identify outstanding challenges and emerging opportunities. The format of the Roadmap, whereby experts in each discipline share their viewpoint and articulate their vision for quantum materials, reflects the dynamic and multifaceted nature of this research area, and is meant to encourage exchanges and discussions across traditional disciplinary boundaries. It is our hope that this collective vision will contribute to sparking new fascinating questions and activities at the intersection of materials science, condensed matter physics, device engineering, and quantum information, and to shaping a clearer landscape of quantum materials science as a new frontier of interdisciplinary scientific inquiry. We stress that this article is not meant to be a fully comprehensive review but rather an up-to-date snapshot of different areas of research on quantum materials with a minimal number of references focusing on the latest developments.

近年来，“量子材料”的概念已经成为横跨科学和工程领域的一个强大的统一概念，从凝聚态物质和冷原子物理学到材料科学和量子计算。除了传统的量子材料，例如非常规的超导体，重费米子和多铁性材料，该领域已大大扩展，涵盖了拓扑量子物质，二维材料及其范德华异质结构，莫尔材料，浮球时间晶体以及材料和器件用马里亚纳费米子进行量子计算。在本路线图系列中，我们旨在捕获该领域最新动态的快照，并确定突出的挑战和新出现的机会。路线图的格式，每个学科的专家可以借此交流他们的观点并阐明他们对量子材料的看法，反映该研究领域的动态和多面性，并旨在鼓励跨越传统学科领域的交流和讨论。我们希望，这种集体愿景将有助于在材料科学，凝聚态物理，设备工程和量子信息的交汇处引发新的有趣的问题和活动，并有助于形成更清晰的量子材料科学前景，成为量子科学的新领域。跨学科的科学探究。我们强调，这篇文章并不是要进行全面的综述，而应该是量子材料研究不同领域的最新快照，而有关最新进展的参考文献最少。
