Compared with traditional communication technology,there are several incomparable advantages in quantum communication technology such as great capacity for memory,high speed operation and absolute communication security.Quantum communication technology is the best option for future military informationization.In this article,the standardization for this attractive and advancing front technology was concerned.The structure of standard system of quantum communication technology and the systematical modulization method of quantum communication equipment were put forward and discussed also,which could afford some references for the future application of quantum communication technology in some military fields such as national defense and security.
With the development of technology, quantum technology with enormous military value has become a key technology related to national information security in the application and development of communication systems. The application of quantum communication technology in military and civilian research is of great significance for China’s future information network construction, as well as the safety of people’s lives and property. One need to increase investment in technology, increase investment in technology, and establish a sound policy system and institutional mechanisms. Only by increasing the promotion of this project can one further promote the development of military civilian integration of quantum communication technology in China and gradually establish a strong quantum communication information network. This article introduced the principles and development of quantum communication, and verified through simulation experiments that quantum technology communication has a lower bit error rate and better performance compared to traditional communication systems.
The article focuses on quantum technologies and the prospects for their application in the defense and security sectors. Based on an analysis of the current state of development of quantum technologies and their applications in defense and security, three main areas are identified: quantum computing, quantum communication, and quantum sensors. For each of these, a specific set of applications, advantages, and limitations is identified. It is noted that quantum computing in defense and security finds application primarily in four subfields: post-quantum cryptography, quantum cryptography, cyber threat detection, and cryptanalysis; quantum communication ensures secure information transmission by utilizing the physical properties of quantum states, particularly the principle of the impossibility of cloning a quantum state, with its primary practical application being Quantum key distribution and its promising application being the quantum internet; quantum sensors are the category of quantum technologies closest to operational deployment, as they utilize the hypersensitivity of quantum states to external disturbances to achieve measurement accuracy unattainable by classical devices. A summary of the main areas of application for quantum technologies in defense and security indicates that quantum sensors have the nearest practical implementation horizon (5–7 years), while quantum computing will have the greatest strategic impact on cryptographic infrastructure due to the threat it poses to existing asymmetric encryption algorithms—which is precisely why the transition to post-quantum standards is becoming urgent. Therefore, given the significant interest in and funding for quantum technologies from both the civilian industry and governments, it is expected that these technologies will continue to develop and new quantum applications will become available over the next five to ten years, and new advances in the development of quantum technologies may bring new opportunities for the military, but for the military to actually reap the benefits of new quantum technologies, they need to actively engage in this field and guide the development and implementation of military applications of quantum technologies.
Due to the advancement of technology, laser communication, fiber optic communication and optical quantum communication have been developed, not only in the field of life, but also in the field of aviation, military and information security. This paper, mainly compares the difference between optical quantum communication and other communication technologies in terms of security and effectiveness, presenting the current state of technology and applications and providing an outlook on future directions. Through the comparison, this paper argues that the application of technology in optical quantum communication can promote the rapid development of quantum communication technology and thus enhance the comprehensive strength of global communication technology.
As the established communication networks no longer meet people’s need in the speed and the security in transferring information, quantum communication draws people’s attention. Taking advantage of the basic quantum properties, quantum communication guarantees the message being delivered promptly and safely. This paper first introduces a general background quantum communication. After that, we introduced the history of the development of quantum communication and Quantum Key Distribution (QKD) as well as the general flow of quantum communication. Based on that, we evaluated a scheme of quantum communication network based on QKD, proposing different methods to improve the security and efficiency of the transmission of information. We encapsulated the history of the development of QKD. We conclude that the improvement of quantum communication depends on the algorithms. While various algorithms are proposed, we discussed a potentially possible way to combine the advantages of the algorithms. However, the actual effectiveness of our method still needs to be testified in future researches.
Quantum communication as a vital branch of quantum information science, leverages physical properties such as quantum superposition, entanglement, and the impossibility of cloning to pioneer entirely new technical pathways for achieving unconditional secure communication. This paper comprehensively and meticulously elucidates the core technological principles of quantum communication, including quantum key distribution, quantum teleportation, and quantum secure direct communication; It also delves into its application status in critical domains such as dedicated communications, finance, and government affairs.
