Quantum technologies include two key high-tech areas: communications and computing. Commercialization of quantum solutions depends on the strategy of managing the corporate ecosystems, i.e., developers and consumers of innovative products. To identify future leaders of the quantum technology ecosystem, the authors studied the medium-term scientific and economic indicators of 150 large companies. Software and hardware developers (Toshiba, Huawei, etc.) are more likely to become technological leaders in quantum communications than service providers (British Telecom, Deutsche Telekom, etc.). Former leaders of electronic computer market also strive for leadership in quantum computing (IBM, Intel). Some companies have projects in both areas; for instance, Amazon, NVidia, Cisco, and NTT can become a link in the synergy of computing and communications, especially when it comes to the quantum Internet. Such industrial, logistics, and financial companies as Volkswagen, BMW, Toyota, Honda, JP Morgan, Credit Agricole, Mitsui, Airbus, and Mitsubishi focus on piloting quantum algorithms. This research may be of interest to Russian organizations responsible for the strategic development of quantum technologies. Domestic communications and computing require new ecosystem companies with extensive experience in innovative R&D.
Quantum communication based on quantum mechanics is a secure communication technology,which can provide unconditional security between communication parties in principle. Recently,quantum communication technology and its practical engineering have been regarded by many counties and regions such as the US,European Union,China and Japan. With the engineering development of quantum communication technology,it has been progressing from point-to-point communications to network applications,including local area networks and wide area networks. Furthermore,global quantum communication is developing. In the review,we summarize in detail the development of the quantum communication networks built by various countries,and introduce the plans of quantum satellites.
Humanity’s social, economic, and technological progress could not have been made without communications infrastructure. The need to attain the sophistication of long-distance communication has grown steadily since the dawn of civilization. The modern global communications system is the single greatest infrastructural project in human history. The global telecommunications grid which uses satellites, deep-sea fiber-optic systems, Wi-Fi, Bluetooth, microwave and other radio, and optical-frequency communications networks are tremendous in coverage, unparalleled in connection, and ubiquitous in application. As we approach the middle of the 21st century, this system’s next major update will incorporate quantum communications technology. Quantum communication, in tandem with quantum computing and quantum sensing, constitutes one of the three pillars of second-generation quantum technology and promises an array of novel applications. Considering the reliable transmission of quantum information often requires the transport of individual particles of light photons through a world inundated by trillions upon trillions of photons, quantum communication systems are an engineering marvel. To provide a technological alternative for existing public-key encryption protocols, which are now susceptible to the threat posed by future quantum computing systems, nascent commercial quantum communication networks aim to realize the potential for cryptographic security provided by the laws of quantum mechanics. However, a number of obstacles must be overcome before quantum communications can be widely adopted. This study focuses on the current state of quantum communication, the promise of its prospects in the near and far future, the obstacles it faces, and the breakthroughs and applications developed by the United Arab Emirates.
The aim of this survey-based study is to provide insights into the current awareness perception and expectations that businesses representatives see in the emerging field of quantum communication technology.Quantum communication is revolutionizing the way we perceive data security, transmission and networking.In a close future we expect to use communication systems that are more secure, efficient, and potentially transformative for various industries.The study focuses on how businesses are preparing for the potential commercial applications of quantum communication, the challenges they might face in integrating this technology, and their expectations for its impact on specific sectors.A further development of the study on larger population and diverse regions would provide relevant information for policy makers in shaping policies and funding strategies to promote the growth of quantum communication.
Quantum information technologies are poised to fundamentally transform global communication. Unlike classical systems, quantum communication leverages phenomena like quantum entanglement to offer unprecedented capabilities. This not only revolutionizes security and computational methods, but also drives advancements in specialized applications such as advanced sensing and precise time synchronization. These developments hold significant implications for critical sectors including medicine and health, materials science, and energy. At the core of this transformation is the concept of a quantum Internet, built upon the unique properties of quantum entanglement. The strategic use of entanglement as a communication resource is expected to profoundly impact the future evolution of the Internet and the development of 6G networks. This paper explores the path from current quantum entanglement research to a global quantum network. It highlights the advantages of satellite-based quantum communications for routing quantum information and discusses the simulation tools essential for designing and optimizing these advanced communication systems.
