Quantum secure direct communication(QSDC)enables the direct transmission of secret messages over a quantum channel without prior key sharing.QSDC implemented in the continuous-variable(CV)regime allows high-capacity information transmission using simple optical communication technologies.In this work,we propose a novel CV-QSDC protocol with a quantum one-time pad,which achieves secure message transmission based on coherent states and unitary operations,and the receiver can directly obtain the secret messages after measuring the coherent states.The security of this protocol is jointly guaranteed by one-time pad encryption and a CV quantum key distribution(QKD)protocol.Performance analysis shows that the proposed scheme can achieve a quantum bit error rate(QBER)lower than 1% by adjusting the modulation variance and unitary operation parameters.With the optimal modulation variance,the secure transmission distance of the proposed protocol can exceed 150 km. 展开更多

Quantum secure direct communication(QSDC) is a communication method based on quantum mechanics and it is used to transmit secret messages. Unlike quantum key distribution, secret messages can be transmitted directly on a quantum channel with QSDC. Higher channel capacity and noise suppression capabilities are key to achieving longdistance quantum communication. Here, we report a continuous-variable QSDC scheme based on mask-coding and orbital angular momentum, in which the mask-coding is employed to protect the security of the transmitting messages and to suppress the influence of excess noise. The combination of orbital angular momentum and information block transmission effectively improves the secrecy capacity. In the 800 information blocks ×1310 bits length 10-km experiment, the results show a statistical average bit error rate of 0.38%, a system excess noise value of 0.0184 SNU, and a final secrecy capacity of 6.319×10~6 bps. Therefore, this scheme reduces error bits while increasing secrecy capacity, providing a solution for long-distance large-scale quantum communication, which is capable of transmitting text, images and other information of reasonable size. 展开更多

OBJECTIVE:To investigate the clinical effect of abdominal moxibustion at the Zhongji(CV3)combined with Yiqi Tonglin Yangyin decoction(益气通淋养阴汤)and antibiotics on elderly women with complicated urinary tract infections.METHODS:One hundred and forty-four elderly female patients diagnosed with complicated urinary tract infections and admitted to our hospital were selected for this study.They were randomly assigned to two groups:the dual treatment group,consisting of 72 patients,treated with antibiotics combined with Yiqi Tonglin Yangyin decoction,and the triple treatment group,comprising 72 patients,who received abdominal moxibustion at the Zhongji(CV3)in addition to the dual treatment.The clinical efficacy,Traditional Chinese Medicine(TCM)syndrome score,immune function indicators,oxidative stress status indicators,symptom recovery,and recurrence were evaluated and compared.RESULTS:Before treatment,there was no statistically significant differences observed in the TCM syndrome score,levels of immunoglobulin A(IgA),immunoglobulin M(IgM),xanthine oxidoreductase(XOD),malondialdehyde(MDA)and superoxide dismutase(SOD)between the two groups(P>0.05).After treatment,the triple group exhibited a significantly higher overall response rate(95.9%>84.7%)compared to the dual group.Moreover,the triple group demonstrated elevated levels of IgA,IgM,and SOD,a lower TCM syndrome score,and reduced levels of XOD and MDA,along with a diminished recurrence rate.Additionally,patients in the triple group experienced a shorter time to return to normal symptoms,bacteriuria,and a routine urine output.CONCLUSION:Abdominal moxibustion at the Zhongji(CV3),combined with Yiqi Tonglin Yangyin decoction and antibiotics for treating complicated urinary tract infections in elderly women,can effectively improve the clinical symptoms,TCM syndromes,and immune function of patients.Additionally,it can reduce oxidative stress,promote patient recovery,and lower the recurrence rate with pronounced comprehensive efficacy. 展开更多

Durian(Durio zibethinus L.)is a tropical fruit of substantial nutritional and economic value from the family Malvaceae.Several genome assemblies for durian have been reported previously,but these assemblies contain gaps that have restricted their completeness and hindered their practical utility for downstream research.Here,we present the first gap-free genome assembly of Durio zibethinus cv.Chuongbo by integrating PacBio HiFi,Oxford Nanopore,and Hi-C sequencing data.The assembled genome is 824.78 Mb across 28 chromosomes,with a scaffold N50 of 30.88 Mb and 44,024 protein-coding genes.Comparative genomic analyses dated the divergence between D.zibethinus cv.Chuongbo and Herrania umbratica to 35 million years ago,and between two durian cultivars to 2 million years ago.D.zibethinus cv.Chuongbo exhibits substantial gene family expansion and a high abundance of species-specific genes,reflecting key genomic innovations underlying its unique biological traits.Additionally,comparative analysis of the TERT gene family across 27 Malvaceae species uncovered strong evolutionary constraints that maintain a predominant single-copy configuration,with two copies identified in several Gossypium taxa.This high-quality,gap-free genome provides a foundational resource for elucidating genome architecture,gene evolution,and the molecular basis of unique traits in durian and related Malvaceae species. 展开更多

We present a Trojan-horse attack on the practical two-way continuous-variable quantum key distribution system. Our attack mainly focuses on the imperfection of the practical system that the modulator has a redundancy of modulation pulsewidth, which leaves a loophole for the eavesdropper inserting a Trojan-horse pulse. Utilizing the unique characteristics of two-way continuous-variable quantum key distribution that Alice only takes modulation operation on the received mode without any measurement, this attack allows the eavesdropper to render all of the final keys shared between the legitimate parties insecure without being detected. After analyzing the feasibility of the attack, the corresponding countermeasures are put forward. 展开更多

Continuous-variable quantum key distribution(CVQKD) protocols with entanglement in the middle(EM) enable long maximal transmission distances for quantum communications. For the security analysis of the protocols, it is usually assumed that Eve performs collective Gaussian attacks and there is a lack of finite-size analysis of the protocols. However,in this paper we consider the finite-size regime of the EM-based CVQKD protocols by exposing the protocol to collective attacks and coherent attacks. We differentiate between the collective attacks and the coherent attacks while comparing asymptotic key rate and the key rate in the finite-size scenarios. Moreover, both symmetric and asymmetric configurations are collated in a contrastive analysis. As expected, the derived results in the finite-size scenarios are less useful than those acquired in the asymptotic regime. Nevertheless, we find that CVQKD with entanglement in the middle is capable of providing fully secure secret keys taking the finite-size effects into account with transmission distances of more than 30 km. 展开更多

The developing tendency of continuous-variable （CV） measurement-device-independent （MDI） quantum cryptography is to cope with the practical issue of implementing sealable quantum networks. Up to now, most theoretical and experimental researches on CV-MDI QKD are focused on two-party protocols. However, we suggest a CV-MDI multipartite quantum secret sharing （QSS） protocol use the EPR states coupled with optical amplifiers. More remarkable, QSS is the real application in multipartite CV-MDI QKD, in other words, is the concrete implementation method of multipartite CV-MDI QKD. It can implement a practical quantum network scheme, under which the legal participants create the secret correlations by using EPR states connecting to an untrusted relay via insecure links and applying the multi-entangled Greenberger-Horne-Zeilinger （GHZ） state analysis at relay station. Even if there is a possibility that the relay may be completely tampered, the legal participants are still able to extract a secret key from network communication. The numerical simulation indicates that the quantum network communication can be achieved in an asymmetric scenario, fulfilling the demands of a practical quantum network. Additionally, we illustrate that the use of optical amplifiers can compensate the partial inherent imperfections of detectors and increase the transmission distance of the CV-MDI quantum system. 展开更多

Considering the ocean water＇s optical attenuation and the roughness of the sea surface, we analyze the security of continuous-variable （CV） quantum key distribution （QKD） based Mr-to-water channel. The effects of the absorp- tion and scattering on the transmittance of underwater quantum channel and the maximum secure transmission distance are studied. Considering the roughness of the sea surface, we simulate the performance bounds of CV QKD with different wind speeds using the Monte Carlo method. The results show that even if the secret key rate gradually reduces as the wind speed increases, the maximum transmission distance will not be affected obviously. Compared to the works regarding short-distance underwater optical communication, our research represents a significant step towards establishing secure communication between air platform and submarine vehicle. 展开更多

Generally, the involved scheme is based on the binary random basis choice. To improve the performance and security, we present a scheme based on a continuous random basis choice. The results show that our scheme obviously improves the performance, such as the secure communication distance. Our scheme avoids comparing the measurement basis and discarding the key bits, and it can be easily implemented with current technology. Moreover, the imperfection of the basis choice can be well removed by the known phase compensation algorithm. 展开更多

We propose a method to improve the secret key rate of an eight-state continuous-variable quantum key distribution（CVQKD） by using a linear optics cloning machine（LOCM）. In the proposed scheme, an LOCM is exploited to compensate for the imperfections of Bob＇s apparatus, so that the generated secret key rate of the eight-state protocol could be well enhanced. We investigate the security of our proposed protocol in a finite-size scenario so as to further approach the practical value of a secret key rate. Numeric simulation shows that the LOCM with reasonable tuning gain λ and transmittance τcan effectively improve the secret key rate of eight-state CVQKD in both an asymptotic limit and a finite-size regime.Furthermore, we obtain the tightest bound of the secure distance by taking the finite-size effect into account, which is more practical than that obtained in the asymptotic limit. 展开更多

We investigate the time evolution of quantum correlations, which are measured by Gaussian quantum discord in a continuous-variable bipartite system subject to common and independent non-Markovian environments. Considering an initial two-mode Gaussian symmetric squeezed thermal state, we show that quantum correlations can be created during the non-Markovian evolution, which is different from the Markovian process. Furthermore, we find that the temperature is a key factor during the evolution in non-Markovian environments. For common reservoirs, a maximum creation of quantum correlations may occur under an appropriate temperature. For independent reservoirs, the non-Markovianity of the total system corresponds to the subsystem whose temperature is higher. In both common and independent environments, the Gaussian quantum discord is influenced by the temperature and the photon number of each mode. 展开更多

The trans-media transmission of quantum pulse is one of means of free-space transmission which can be applied in continuous-variable quantum key distribution(CVQKD)system.In traditional implementations for atmospheric channels,the 1500-to-1600-nm pulse is regarded as an ideal quantum pulse carrier.However,the underwater transmission of this pulses tends to suffer from severe attenuation,which inevitably deteriorates the security of the whole CVQKD system.In this paper,we propose an alternative scheme for implementations of CVQKD over satellite-to-submarine channels.We estimate the parameters of the trans-media channels,involving atmosphere,sea surface and seawater and find that the shortwave infrared performs well in the above channels.The 450-nm pulse is used for generations of quantum signal carriers to accomplish quantum communications through atmosphere,sea surface and seawater channels.Numerical simulations show that the proposed scheme can achieve the transmission distance of 600 km.In addition,we demonstrate that non-Gaussian operations can further lengthen its maximal transmission distance,which contributes to the establishment of practical global quantum networks. 展开更多

We investigate the fundamental limits to the achievable tripartite continuous-variable （CV） entanglement criterion of a generalized Vl criterion. Our numerical simulation results show that the non-degenerate eigenvalues do effect the performances of the estimated minimum variances. From below the threshold to above the threshold, with the increase of the pump parameter, the tripartite CV entanglement gradually disappears. The different off-diagonal elements seriously distort the weights for entanglement. We can obtain a good tripartite CV entanglement by appropriately controlling the values of off-diagonal elements eij. 展开更多
