| 1 | Quantum network coding for multi-unicast problem based on 2D and 3D cluster states显示文摘We mainly consider quantum multi-unicast problem over directed acyclic network, where each source wishes to transmit an independent message to its target via bottleneck channel. Taking the advantage of global entanglement state 2D and 3D cluster states, these problems can be solved efficiently. At first, a universal scheme for the generation of resource states among distant communication nodes is provided. The corresponding between cluster and bigraph leads to a constant temporal resource cost. Furthermore, a new approach based on stabilizer formalism to analyze the solvability of several underlying quantum multi-unicast networks is presented. It is found that the solvability closely depends on the choice of stabilizer generators for a given cluster state. And then, with the designed measurement basis and parallel measurement on intermediate nodes, we propose optimal protocols for these multi-unicast sessions. Also, the analysis reveals that the resource consumption involving spatial resources, operational resources and temporal resources mostly reach the lower bounds. | Jing LI Xiubo CHEN Xingming SUN Zongpeng LI Yixian YANG | 2016 | Science China(Information Sciences)2016，59，4： | 4 |

| 5 | Controlled Secure Direct Communication Protocol via the Three-Qubit Partially Entangled Set of States显示文摘In this paper,we first re-examine the previous protocol of controlled quantum secure direct communication of Zhang et al.’s scheme,which was found insecure under two kinds of attacks,fake entangled particles attack and disentanglement attack.Then,by changing the party of the preparation of cluster states and using unitary operations,we present an improved protocol which can avoid these two kinds of attacks.Moreover,the protocol is proposed using the three-qubit partially entangled set of states.It is more efficient by only using three particles rather than four or even more to transmit one bit secret information.Given our using state is much easier to prepare for multiqubit states and our protocol needs less measurement resource,it makes this protocol more convenient from an applied point of view. | Gang Xu Ke Xiao Zongpeng Li Xin-Xin Niu Michael Ryan | 2019 | Computers, Materials & Continua2019，，3： | 1 |

| 7 | Copper-catalyzed asymmetric 1,3-dipolar cycloaddition of azomethine ylides withβ-trifluoromethyl-substituted alkenyl heteroarenes显示文摘Copper-catalyzed asymmetric 1,3-dipolar cycloaddition of azomethine ylides andβ-trifluoromethyl-substituted alkenyl heteroarenes was developed for the first time.A wide range of enantioenriched pyrrolidines containing both heteroarenes and trifluoromethyl group with multiple stereogenic centers could be readily accessible by this method with good to high yields and excellent levels of both stereo-and regioselectivity(up to 99%yield,>20:1 rr,>20:1 dr,and up to 95%ee).Notably,substratecontrolled umpolung-type dipolar cycloaddition was also disclosed in this protocol to achieve regiodivergent synthesis withα-aryl substituted aldimine esters as the dipole precursors.Systematic DFT studies were conducted to explore the origin of the stereo-and regioselectivity of this 1,3-dipolar cycloaddition,and suggest that copper(Ⅱ)salt utilized in this catalytic system could be reduced in-situ to the active copper(Ⅰ)species and might be responsible for the observed high stereo-and regioselectivity. | Xiang Cheng Xin Chang Yuhong Yang Zongpeng Zhang Jing Li Yipu Li Wenxiao Zhao Lung Wa Chung Huailong Teng Xiu-Qin Dong Chun-Jiang Wang | 2023 | Science China Chemistry2023，66，11： | 0 |
| 8 | Supercritical CO_(2)-driven,periodic patterning on one-dimensionals carbon nanomaterials显示文摘One-dimensional carbon nano-materials,in particular carbon nanotubes (CNTs) and carbon nanofibers (CNFs),are of scientific and technological interest due to their satisfactory properties and ability to serve as templates for directed assembly.In this work,linear high density polyethylene (PE) was periodically decorated on CNTs and CNFs using a supercritical carbon dioxide (scCO_(2))antisolvent-induced polymer epitaxy (SAIPE) method,leading to nano-hybrid shish-kebab (NHSK) structures.The formation mechanism of different morphologies of PE lamellae on CNTs and CNFs has been discussed.Palladium nanoparticles were synthesized and immobilized on the PE/CNF NHSK structure with the assistance of scCO_(2).The obtained hierarchical nano-hybrid architecture may find applications in microfabrication and other related fields. | ZHENG XiaoLi XU Qun LI ZongPeng | 2010 | Science China Chemistry2010，53，7： | 0 |
| 9 | Pressure manipulation of ultrafast carrier dynamics in monolayer WS_(2)显示文摘Two-dimensional transition metal dichalcogenides(TMDs)have intriguing physic properties and offer an exciting platform to explore many features that are important for future devices.In this work,we synthesized monolayer WS_(2)as an example to study the optical response with hydrostatic pressure.The Raman results show a continuous tuning of the lattice vibrations that is induced by hydrostatic pressure.We further demonstrate an efficient pressure-induced change of the band structure and carrier dynamics via transient absorption measurements.We found that two time constants can be attributed to the capture process of two kinds of defect states,with the pressure increasing from 0.55 GPa to 2.91 GPa,both of capture processes were accelerated,and there is an inflection point within the pressure range of 1.56 GPa to 1.89 GPa.Our findings provide valuable information for the design of future optoelectronic devices. | Yao Li Haiou Zhu Zongpeng Song | 2023 | Journal of Semiconductors2023，44，8： | 0 |
| 10 | Verifiable Multi-Party Universal Blind Quantum Computing in Distributed Networks显示文摘Blind quantum computing(BQC)ensures that a classical client could delegate complex computing tasks to a remote quantum server safely.In order to detect the dishonest behavior of the participants,we present a verifiable multi-party universal BQC protocol in distributed networks.By using the stabilizer formalism,we propose an honesty check method to test the correctness of the graph states generated by the servers.The honesty of both the clients and the servers can be judged fairly with the help of the arbitrator.Moreover,a load balancer is introduced to control the possible breakdown of servers in the network.No-signaling principle ensures the unconditional security of the protocol.Through the use of universal resource states,our protocol can be applied in more multi-party verifiable universal BQC protocols.The failure management and workload balancing of the protocol also provide a promising prospect for the future BQC network. | SHAN Ruiting CHEN Xiubo XU Gang DOU Zhao LI Zongpeng MIAO Lihua YANG Yixian | 2021 | Chinese Journal of Electronics2021，30，4： | 0 |
