The quantum cryptography patent data can well reflect the pro- gress and achievement in quantum cryptography field of a country, which reveals the relevant scientific and technological strength and national defense strength of a country. This paper makes a detailed analysis of patent applications from 2000 to 2017 in four major quantum research and development regions in the world, namely the United States, the European Union, Japan and China. The analysis is carried out from three aspects of patent application time, patent application organization and patent classification number. And then the research results in quantum cryptography field of the countries above are summarized and the research trends are predicted. These provide an intuitive and detailed data support for the analysis of a country’s scientific and technological strength. Moreover, it can be an important reference for further research on developments of global quantum technology and the national quantum strategic planning.
In the early decades of the 20th century, the inception of quantum mechanics catalyzed the first quantum revolution, resulting in groundbreaking technological advances, such as nuclear energy, semiconductors, lasers, nuclear magnetic resonance, superconductivity, and global satellite positioning systems. These innovations have promoted significant progress in material civilization, fundamentally changed the way of life and societal landscape of humanity. Since the 1990s, quantum control technology has made significant strides forward, ushering in a rapid evolution of quantum technologies, notably exemplified by quantum information science. This encompasses domains such as quantum communication, quantum computing, and quantum precision measurement, offering paradigm-shifting solutions for enhancing information transmission security, accelerating computational speed, and elevating measurement precision. These advances hold the potential to provide crucial underpinning for national security and the high-quality development of the national economy. The swift progression of quantum information technology heralds the advent of the second quantum revolution. Following nearly three decades of concerted efforts, China’s quantum information technology field as a whole has achieved a leap. Specifically, China presently assumes a prominent international role in both the research and practical application of quantum communication, leading the global domain in quantum computing, and achieving international preeminence or advanced standing across various facets of quantum precision measurement. Presently, it is imperative to conduct a comprehensive assessment of the developmental priorities in the realm of quantum information in China for the forthcoming 5 to 10 years, in alignment with national strategic priorities and the evolving landscape of international competition. This will enable the proactive establishment of next-generation information technology systems that are secure, efficient, autonomous, and controllable.
The article examines the current level of quantum technologies development worldwide and specifically in Russia. Currently, the quantum technology market is in the formative stage and a limited number of countries produce competitive samples. Quantum innovations can upend a number of industries, and the possession of such technologies may give a significant boost to the development of the national economy. Despite external constraints and economic uncertainty, Russia remains a significant player in the emerging industry. With an extensive research base and some unique developments, Russia can occupy an important niche in the market and get closer to the industry leaders such as the United States and China. The study identified potential directions for the further development of quantum technologies in Russia and the ways to achieve the established goals.
Quantum communication technology is emerging as a transformative area in telecommunications, with the potential to revolutionize how data is transmitted, secured, and processed globally.The global quantum computing and communication market is expected to grow rapidly as major technology firms are contributing to the development of quantum communication hardware and software, signaling the commercial potential of such technology. This paper presents a comparative study of quantum communication across different regions (China, the United States, and the European Union). The result indicates distinct approaches, technological advancements, and strategic goals.
Quantum communication is a key to information security, which has a wide range of applications in military, financial, and social development.
