| 1 | Revisiting the security of quantum dialogue and bidirectional quantum secure direct communication显示文摘From the perspective of information theory and cryptography,the security of two quantum dialogue protocols and a bidirectional quantum secure direct communi-cation(QSDC) protocol was analyzed,and it was pointed out that the transmitted information would be partly leaked out in them.That is,any eavesdropper can elicit some information about the secrets from the public annunciations of the legal us-ers.This phenomenon should have been strictly forbidden in a quantum secure communication.In fact,this problem exists in quite a few recent proposals and,therefore,it deserves more research attention in the following related study. | GAO Fei GUO FenZhuo WEN QiaoYan ZHU FuChen | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，5： | 28 |

| 3 | Quantum secure direct communication over the collective amplitude damping channel显示文摘An efficient quantum secure direct communication protocol is presented over the amplitude damping channel.The protocol encodes logical bits in two-qubit noiseless states,and so it can function over a quantum channel subjected to collective amplitude damping.The feature of this protocol is that the sender encodes the secret directly on the quantum states,the receiver decodes the secret by performing determinate measurements,and there is no basis mismatch.The transmission's safety is ensured by the nonorthogonality of the noiseless states traveling forward and backward on the quantum channel.Moreover,we construct the efficient quantum circuits to implement channel encoding and information encoding by means of primitive operations in quantum computation. | QIN SuJuan WEN QiaoYan MENG LuoMing ZHU FuChen | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，8： | 9 |
| 4 | Stability of coal pillar in gob-side entry driving under unstable overlying strata and its coupling support control technique显示文摘Considering the situation that it is difficult to control the stability of narrow coal pillar in gob-side entry driving under unstable overlying strata, the finite difference numerical simulation method was adopted to analyze the inner stress distribution and its evolution regularity, as well as the deformation characteristics of narrow coal pillar in gob-side entry driving, in the whole process from entry driving of last working face to the present working face mining. A new method of narrow coal pillar control based on the triune coupling support technique (TCST), which includes that high-strength prestressed thread steel bolt is used to strain the coal on the goaf side, and that short bolt to control the integrity of global displacement zone in coal pillar on the entry side, and that long grouting cable to fix anchor point to constrain the bed separation between global displacement zone and fixed zone, is thereby generated and applied to the field production. The result indicates that after entry excavating along the gob under unstable overlying strata, the supporting structure left on the gob side of narrow coal pillar is basically invalid to maintain the coal-pillar stability, and the large deformation of the pillar on the gob side is evident. Except for the significant dynamic pressure appearing in the coal mining of last working face and overlying strata stabilizing process, the stress variation inside the coal pillar in other stages are rather steady, however, the stress expansion is obvious and the coal pillar continues to deform. Once the gob-side entry driving is completed, a global displacement zone on the entry side appears in the shallow part of the pillar, whereas, a relatively steady fixed zone staying almost still in gob-side entry driving and present working face mining is found in the deep part of the pillar. The application of TCST can not only avoid the failure of pillar supporting structure, but exert the supporting capacity of the bolting structure left in the pillar of last sublevel entry, thus to jointly maintain the stability of coal pillar. | Yuan Zhang Zhijun Wan Fuchen Li Changbing Zhou Bo Zhang Feng Guo Chengtan Zhu | 2013 | International Journal of Mining Science and Technology2013，23，2： | 8 |
| 5 | Comparing the efficiencies of different detect strategies in the ping-pong protocol显示文摘The way to compare the efficiencies of different detect strategies (DSs) in the 'ping-pong' protocol is studied. The trade-off between information gain and dis- turbance is calculated and compared for different DSs. The comparison result primely tallies with our intuitional analysis. It is shown that the analysis of this trade-off is a feasible way to compare the performances of different DSs in theory. | GAO Fei GUO FenZhuo WEN QiaoYan ZHU FuChen | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，12： | 7 |
| 6 | Quantum asymmetric cryptography with symmetric keys显示文摘Based on quantum encryption,we present a new idea for quantum public-key cryptography (QPKC) and construct a whole theoretical framework of a QPKC system. We show that the quantum-mechanical nature renders it feasible and reasonable to use symmetric keys in such a scheme,which is quite different from that in conventional public-key cryptography. The security of our scheme is analyzed and some features are discussed. Furthermore,the state-estimation attack to a prior QPKC scheme is demonstrated. | GAO Fei WEN QiaoYan QIN SuJuan ZHU FuChen | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，12： | 6 |
| 7 | Quantum communications with an anonymous receiver显示文摘A new protocol for the anonymous communication of quantum information is proposed. The anonymity of the receiver and the privacy of the quantum information are perfectly protected except with exponentially small probability in this protocol. Furthermore, this protocol uses single photons to construct anonymous entanglement instead of multipartite entangled states, and therefore it reduces quantum resources compared with the pioneering work. | WANG TianYin 1,2* , WEN QianYan 1 & ZHU FuChen 3 1 State Key Laboratory of Networking and Switching Technology, Beijing University of Posts and Telecommunications, Beijing 100876, China 2 School of Mathematical Science, Luoyang Normal University, Luoyang 471022, China 3 National Laboratory for Modern Communications, Chengdu 610041, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，12： | 5 |
| 8 | Isolation and Characterization of a Cinnamoyl CoA Reductase Gene(CCR) in Pear(Pyrus pyrifolia)显示文摘Pear is a popular and commercially important fresh fruit, and its texture is related to the presence of sclereid formatted by parenchyma cell with lignification in vascular plants. Previous studies have demonstrated that content of lignin may be regulated by cinnamoyl CoA reductase(CCR) in various plants. However, the function of CCR in pears remains very limited. In the present study, we isolated a cDNA encoding CCR(PpCCR, GenBank accession No. KF999958) and its promoter(proPpCCR) from Whangkeumbae pear to investigate the function of CCR in lignin biosynthesis. PpCCR-GFP expressed in rice mesophyll protoplast demonstrated that PpCCR-GFP was localized in the cytoplasm, indicating that CCR may function in cytoplasm without localization signals. In transgenic plants carrying PpCCR, we observed higher lignin content compared with that in wild type plants, further suggesting that PpCCR can affect the lignin contents through regulating lignin biosynthesis in Arabidopsis thaliana. More studies in other plants are needed to confirm our conclusion. | Meng HU Boya TAN Tao WU Xianming LI Junfan TU Fuchen YANG Hongyan ZHU Zhongqi QIN | 2014 | Agricultural Science & Technology2014，15，6： | 2 |
| 9 | Phase-pure two-dimensional Fe_(X)GeTe_(2) magnets with near-room-temperature Tc显示文摘Two-dimensional(2D)ferromagnets with out-of-plane(OOP)magnetic anisotropy are potential candidates for realizing the next-generation memory devices with ultra-low power consumption and high storage density.However,a scalable approach to synthesize 2D magnets with OOP anisotropy directly on the complimentary metal-oxide semiconductor(CMOS)compatible substrates has not yet been mainly explored,which hinders the practical application of 2D magnets.This work demonstrates a cascaded space confined chemical vapor deposition(CS-CVD)technique to synthesize 2D FexGeTe_(2) ferromagnets.The weight fraction of iron(Fe)in the precursor controls the phase purity of the as-grown FexGeTe2.As a result,high-quality Fe_(3)GeTe_(2) and Fe_(5)GeTe_(2) flakes have been grown selectively using the CS-CVD technique.Curie temperature(Tc)of the as-grown FexGeTe2 can be up to-280 K,nearly room temperature.The thickness and temperature-dependent magnetic studies on the Fe_(5)GeTe_(2) reveal a 2D Ising to 3D XY behavior.Also,Terahertz spectroscopy experiments on Fe_(5)GeTe_(2) display the highest conductivity among other FexGeTe_(2) 2D magnets.The results of this work indicate a scalable pathway for the direct growth and integration of 2D ternary magnets on CMOS-based substrates to develop spintronic memory devices. | Govindan Kutty Rajendran Nair Zhaowei Zhang Fuchen Hou§ Ali Abdelaziem Xiaodong Xu Steve Wu Qing Yang Nan Zhang Weiqi Li Chao Zhu Yao Wu Heng Weiling Lixing Kang Teddy Salim Jiadong Zhou Lin Ke Junhao Lin Xingji Li Weibo Gao Zheng Liu | 2022 | Nano Research2022，15，1： | 0 |
| 10 | Simultaneous splenectomy improving the outcomes of patients with hepatocellular carcinoma,cirrhosis and portal hypertension treated with hepatectomy显示文摘Aims:Patients with cirrhosis and clinically significant portal hypertension(CSPH)usually have concomitant secondary hypersplenism,and splenectomy(Spx)is an option for treating these patients in the Asia‐Pacific region.CSPH is the most important risk factor for postoperative liver dysfunction(PLD)in patients with hepatocellular carcinoma(HCC)and cirrhosis undergoing liver resection.However,the impact of simultaneous Spx and hepatectomy in patients with HCC and CSPH remains unclear.In this study,we aimed to determine the impact of simultaneous Spx on the posthepatectomy outcomes in these patients.Methods:This study included 691 consecutive patients with hepatitis B virusrelated HCC,cirrhosis,and CSPH.These included 565 patients who underwent hepatectomy only(non‐Spx group)and 126 who underwent simultaneous hepatectomy and splenectomy(Spx group).We analyzed the effect of 25 preoperative and 5 intraoperative factors on postoperative outcomes using logistic regression.To overcome any possible selection bias,confounders were balanced by propensity score matching(PSM)and inverse probability of treatment weighting(IPTW)analyses,and subgroup analyses were performed within the PSM‐matched groups.Results:Logistic regression analyses revealed that Spx was an independent protective factor for severe postoperative liver dysfunction(SPLD;odds ratio[OR]=0.22,95%confidence interval[CI]:0.11–0.43,p<0.001)and 90‐day SPLD‐related mortality(OR=0.21,95%CI:0.06–0.55,p=0.004),respectively.Spx was also independently associated with a higher overall survival rate(hazard ratio=0.63,95%CI=0.47–0.85,p=0.002)based on Cox regression analysis.PSM and IPTW models showed that the benefit of Spx was also consistent across the major and minor hepatectomy subgroups examined.Conclusion:Simultaneous Spx improved the outcomes of patients with HCC,cirrhosis,and CSPH treated with hepatectomy,including patients who underwent major and minor hepatectomies. | Fuchen Liu Xinggang Guo Wenli Zhang Minghao Zou Jian Huang Wei Dong Jinmin Zhang Xiuli Zhu Zeya Pan Wan Yee Lau Weiping Zhou Hui Liu | 2022 | Portal Hypertension & Cirrhosis2022，1，2： | 0 |
| 11 | Eavesdropping on the Orderly-Encrypting Multiparty Quantum Secret Sharing Protocols显示文摘We discuss the security of the kind of multiparty quantum secret sharing protocols encrypting in series. It is secure against the eavesdroppers outside. However it is weak to withstand the attack of insider with a fake signal and cheating. An idiographic attack strategy is given based on the protocol. Furthermore, we conclude the key leak of the protocols and present a possible way to prevent the dishonest agents from stealing the secret. | QIN Sujuan WEN Qiaoyan ZHU Fuchen | 2006 | Wuhan University Journal of Natural Sciences2006，11，6： | 0 |
| 12 | Quantum Secret Sharing Protocols with High Efficiency显示文摘Measuring the two photons from a Bell state will yield certain correlations between the measurement results. Based on this feature, two quantum secret sharing protocols were proposed. The security against several general attacks was analysed and it was shown that both schemes are secure in theory. Furthermore, both schemes achieve full efficiency and there is no need to utilize multi-particle entanglement, which is relatively more difficult to generate. | GAO Fei WEN Qiaoyan ZHU Fuchen | 2007 | Wuhan University Journal of Natural Sciences2007，12，1： | 0 |
