In this paper, we propose certain different design ideas on a novel topic in quantum cryptography — quantum operation sharing(QOS). Following these unique ideas, three QOS schemes, the "HIEC"(The scheme whose messages are hidden in the entanglement correlation), "HIAO"(The scheme whose messages are hidden with the assistant operations) and "HIMB"(The scheme whose messages are hidden in the selected measurement basis), have been presented to share the single-qubit operations determinately on target states in a remote node. These schemes only require Bell states as quantum resources. Therefore, they can be directly applied in quantum networks, since Bell states are considered the basic quantum channels in quantum networks. Furthermore, after analyse on the security and resource consumptions, the task of QOS can be achieved securely and effectively in these schemes.

应用3D打印技术制备准固态微型超级电容器(MSCs)在可编程结构设计和高质量负载电极制造方面具有固有的优势.然而,缺乏高性能的可打印墨水和厚电极内缓慢的离子传输,对其实际电荷存储能力提出了重大挑战.本文成功开发了一种具有优异流变性能的新型NiCo_(2)S_(4)基纳米复合墨水,并结合直墨书写的3D打印技术合理设计了准固态MSCs的三维结构.得益于牢固锚定在还原氧化石墨烯(rGO)表面的NiCo_(2)S_(4)纳米颗粒和有序的三维微孔,锯齿状厚电极提供了丰富的反应位点并增强了离子传输.因此,三层锯齿状MSCs的面电容高达416.7 mF cm^(-2).在1 mA cm^(-2)的电流密度下,单层、双层和三层电极的锯齿状MSCs的面电容与相对应的网格状MSCs相比,分别增加了127.1%、349.8%和585.9%.本工作为高面电容MSCs的材料和电极结构的跨尺度设计提供了新见解,推动了MSCs在柔性便携式电子设备中的集成应用研究.
