High-order quantum coherence reveals the statistical correlation of quantum particles. Manipulation of quantum coherence of light in the temporal domain enables the production of the single-photon source, which has become one of the most important quantum resources. High-order quantum coherence in the spatial domain plays a crucial role in a variety of applications, such as quantum imaging, holography, and microscopy. However, the active control of second-order spatial quantum coherence remains a challenging task. Here we predict theoretically and demonstrate experimentally the first active manipulation of second-order spatial quantum coherence,which exhibits the capability of switching between bunching and anti-bunching, by mapping the entanglement of spatially structured photons. We also show that signal processing based on quantum coherence exhibits robust resistance to intensity disturbance. Our findings not only enhance existing applications but also pave the way for broader utilization of higher-order spatial quantum coherence.

提出一种通过石墨涂敷处理(GCT)泡沫铝夹芯板(AFS)前驱体来提高其在粉末冶金发泡过程中传热效率的新方法。研究不同传热方法的升温和膨胀特征以及对泡孔结构和抗弯性能的影响。结果表明,前驱体在采用GCT后,升温速度增加近2倍,这提高了AFS的膨胀率、改善了泡孔尺寸均匀性和外部面板形态。此外,在发泡后期阶段具有更加平稳的升温速率,这有助于提高泡孔圆度,并减少泡壁内微孔缺陷。这些改变使AFS的弯曲强度和吸能性能得以显著提高。值得注意的是,因为热传递速率不受板幅尺寸的影响,GCT技术在大尺寸AFS的生产中具有巨大潜力。

大数据时代各种数据权益保护学说值得进一步反思与检讨。数据权益保护问题在我国既有规则体系内完全能够得到妥善解决。因数据的非排他性与权利的排他效力间的根本冲突,数据权益难以被纳入绝对权或相对权中进行保护,而各类新型数据权利混淆了权利在民法体系中的定位,忽视了体系功能,甚至阻遏数据的共享与流通。从体系逻辑、制度调适成本与数据治理全球发展方向来看,数据权益应当被纳入法益保护模式中。数据法益保护应以事实控制状态为基础,将数据权益直接归属于事实控制人,保护范围以各个主体享有的事实利益范围为限。数据产权分置政策应经法律解释还原为数据法益归属确认的基础前提与数据主体行为规范的设计方向。

Zirconium hydride(ZrH_(2)) is an ideal neutron moderator material. However, radiation effect significantly changes its properties, which affect its behavior and the lifespan of the reactor. The threshold energy of displacement is an important quantity of the number of radiation defects produced, which helps us to predict the evolution of radiation defects in ZrH_(2).Molecular dynamics(MD) and ab initio molecular dynamics(AIMD) are two main methods of calculating the threshold energy of displacement. The MD simulations with empirical potentials often cannot accurately depict the transitional states that lattice atoms must surpass to reach an interstitial state. Additionally, the AIMD method is unable to perform largescale calculation, which poses a computational challenge beyond the simulation range of density functional theory. Machine learning potentials are renowned for their high accuracy and efficiency, making them an increasingly preferred choice for molecular dynamics simulations. In this work, we develop an accurate potential energy model for the ZrH_(2) system by using the deep-potential(DP) method. The DP model has a high degree of agreement with first-principles calculations for the typical defect energy and mechanical properties of the ZrH_(2) system, including the basic bulk properties, formation energy of point defects, as well as diffusion behavior of hydrogen and zirconium. By integrating the DP model with Ziegler–Biersack–Littmark(ZBL) potential, we can predict the threshold energy of displacement of zirconium and hydrogen in ε-ZrH_(2).
