Entanglement in macroscopic systems, as a fundamental quantum resource, has been utilized to propel the advancement of quantum technology and probe the boundary between the quantum and classical realms. This study focuses on a unique hybrid quantum system comprising of an ensemble of silicon vacancy (SiV) centers coupled to phononic waveguides in diamond via strain interactions. By employing two sets of time-dependent, non-overlapping driving fields, we investigate the generation process and dynamic properties of macroscopic quantum entanglement, providing fresh insights into the behavior of such hybrid quantum systems. Furthermore, it paves the way for new possibilities in utilizing quantum entanglement as an information carrier in quantum information processing and quantum communication.

高附加值利用废弃塑料要求再生塑料具有良好的性能,为此对比研究了高端再生聚碳酸酯(R-PC)材料(含有质量分数为50%的消费后物理回收的聚碳酸酯原材料)和原生聚碳酸酯(V-PC)材料化学结构、杂质元素、流变性能和介电性能,并进一步分析了热老化(120℃)和湿热老化(80℃,80%湿度)对材料光学性能和力学性能的影响。结果表明,R-PC材料化学结构保持良好,未发现明显的降解。R-PC材料中含有少量氯、铁、钙等杂质,质量分数分别为0.0009%,0.0007%和0.0011%。R-PC材料与V-PC材料流变性能相近,没有明显的支化和交联现象,可采用类似的加工设备和相近的工艺条件对R-PC材料进行加工。R-PC材料热老化和湿热老化的性能变化趋势与V-PC保持良好的一致性,老化后两种材料的光学性能和力学性能整体相差不大,R-PC的断裂伸长率更容易受热老化和湿热老化的影响。整体来讲,高端R-PC材料具有良好的力学性能、光学性能以及良好的热老化和湿热老化稳定性。

数字技术在促进经济增长和改善社会福祉方面发挥了积极作用,成为实现经济和社会高质量发展的重要引擎。数字技术是促进健康人力资本积累的重要途径和实现人口高质量发展的关键支撑。本文从理论层面系统阐述了数字技术促进健康人力资本积累的逻辑机制,并采用全球118个国家1990—2020年跨国面板数据,结合不同国家经济发展水平差异,从人口“生命长度和生命质量”两个维度,实证检验数字技术对健康人力资本积累的具体影响。研究发现,数字技术在大健康领域的广泛应用,有助于降低人口死亡率、提高人口健康预期寿命,进而促进健康人力资本积累;其作用途径主要通过提高政府卫生支出效率、提升数字健康素养、增加闲暇时间和促进环境改善四个路径来实现;数字技术在改善健康人力资本方面的差异与国家经济发展水平差距密切相关。基于以上分析,研究认为应加大医疗技术创新,发挥新型举国体制的优势,集中力量技术攻关,实现现代数字技术、医疗健康大数据、医疗全流程、医疗健康行业相关方多要素融合,创新中国式精准医疗发展模式。

The REAgSb_(2)(RE = rare earth and Y) family has drawn considerable research interest because the two-dimensional Sb net in their crystal structures hosts topological fermions and hence rich topological properties. We report herein the magnetization and magnetotransport measurements of SmAgSb_(2) single crystal, which unveil very large magnetoresistance and high carrier mobility up to 6.2 × 10^(3)% and 5.58 × 10^(3)cm^(2)·V^(-1)·s^(-1), respectively. The analysis of both Shubnikov–de Haas and de Haas–van Alphen quantum oscillations indicates nontrivial Berry phases in the paramagnetic state while trivial Berry curvature in the antiferromagnetic state, indicating a topological phase transition induced by the antiferromagnetic order. It is also supported by the first-principles calculations. The results not only provide a new interesting topological material but also offer valuable insights into the correlation between magnetism and nontrivial topological states.
