This IMPRESS-U project is jointly funded by NSF, National Science Center of Poland (NCN), US National Academy of Sciences, and Office of Naval Research Global (DoD). The research will be performed in a multilateral international partnership that unites Tulane University, University of Pittsburgh (US), Institute of Physics, Polish Academy of Sciences (IFPAN, Poland), and B. Verkin Institute for Low Temperature Physics and Engineering (ILTPE), Kharkiv Polytechnic Institute and Karazin Kharkiv National University (Ukraine). US portion of the collaborative effort will be co-funded by NSF OISE/OD, OIA/EPSCoR, MPS/PHY, MPS/DMR, and MPS/OSI.Part 1: Non-technical description: This project will explore the potential of a materials family and combinations that are new to quantum information science, Pb and Sn chalcogenide semiconductors, coupled to superconductors, as a platform for the discovery of quantum dynamics phenomena in nanoscale devices. The international research team will investigate whether this materials platform unlocks the door to novel quantum dynamics regimes, bringing about opportunities for the discovery of new modalities of quantum control and towards improving quantum device performance. The international team of theoretical physicists, experimentalists and crystal growers will establish an effort to elaborate the materials, characterize them, build quantum devices and analyze and predict theoretically the novel quantum dynamics in these systems, by working in a single and coherent feedback loop process. Project members will engage in educational activities at two of the Kharkiv largest universities – Kharkiv Polytechnic Institute and Karazin Kharkiv National University. Cooperation with the fledgling quantum industry for technology transfer and workforce training will be explored; the team is in discussion with several global quantum computing companies.Part 2: Technical description:The project will focus on materials such as PbTe, PbSe, SnTe and SnSe, as well as their ternary combinations (e.g. PbSnTe). Their potential for quantum science is in their unique properties: strong spin-orbit interaction, large Lande g-factors make them attractive for quantum control of the spin degree of freedom. High electron mobilities and efficient electrostatic gating are advantages for a host of quantum device types, in particular topological Majorana devices. The possibility to make contacts to superconductors such as Pb, Al, Sn, MoTe, is important for superconducting qubits. Beyond these, PbSe and PbTe possess an extraordinarily large dielectric constant which can be leveraged to enter new regimes – with quenched charging energy, opening new pathways for discovery of quantum dynamical effects. The team will organize a hybrid quantum seminar for bringing together the international community around the topic of quantum science. The project will also conduct a conference and a summer school to further integrate the Ukrainian researchers into the global efforts in the field. The team will create an online course on materials for quantum computing. Outreach to the local communities including high school and public is planned.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该 IMPRESS-U 项目由美国国家科学基金会、波兰国家科学中心 (NCN)、美国国家科学院和全球海军研究办公室 (DoD) 联合资助。该研究将在杜兰大学的多边国际合作伙伴关系下进行。 、匹兹堡大学（美国）、波兰科学院物理研究所（IFPAN，波兰）、B. Verkin 低温物理与工程研究所 (ILTPE)、哈尔科夫理工学院和 Karazin Kharkiv国立大学（乌克兰）的美国部分合作项目将由 NSF OISE/OD、OIA/EPSCoR、MPS/PHY、MPS/DMR 和 MPS/OSI 共同资助。第 1 部分：非技术描述：该项目将探索量子信息科学中的新材料系列和组合的潜力，即与超导体耦合的铅和锡硫族化物半导体，作为发现纳米级量子动力学现象的平台国际研究团队将研究该材料平台是否打开了新的量子动力学机制的大门，为发现量子控制的新模式和提高量子器件性能带来了机会。种植者将通过在单一且连贯的反馈循环过程中工作，努力精制材料，表征它们，构建量子设备并从理论上分析和预测这些系统中的新颖量子动力学。项目成员将在其中两个参与教育活动。哈尔科夫最大的大学 –哈尔科夫理工学院和卡拉津哈尔科夫国立大学将探索与新兴量子产业在技术转让和劳动力培训方面的合作；该团队正在与多家全球量子计算公司进行讨论。第二部分：技术描述：该项目将重点关注诸如此类的材料。如 PbTe、PbSe、SnTe 和 SnSe 及其三元组合（例如 PbSnTe），它们在量子科学方面的潜力在于其独特的性质：强自旋轨道相互作用、大朗德。 g 因子使它们对于自旋自由度的量子控制具有吸引力。高电子迁移率和高效的静电门控对于许多量子器件类型来说都是有利的，特别是拓扑马约拉纳器件。 Al、Sn、MoTe 对于超导量子位非常重要，除此之外，PbSe 和 PbTe 还具有非常大的介电常数，可以利用它们进入新的状态——具有淬灭的充电能量，该团队将组织一次混合量子研讨会，围绕量子科学主题聚集国际社会，并举办一次会议和暑期学校，以进一步将乌克兰研究人员融入其中。该团队的努力将创建一个有关量子计算材料的在线课程，计划向包括高中和公众在内的当地社区推广。该奖项是 NSF 的法定使命，并通过使用基金会的知识进行评估，被认为值得支持。优点和更广泛的影响审查标准。
