The research fields of quantum information processing and communication are now well established, although still growing and developing. It was realized early on that there is significant potential for new technologies and applications, leading to the vision of a whole new quantum information technology industry. The vision is not yet reality, and there are many open questions with regard to how it might become so. This article raises some of these questions, and gives a viewpoint on how we might proceed, from where we are today towards a quantum information technology industry in the future.

Quantum Communication becomes a new field of communication technologies with highly diverse applications, and much complexity, and is a promising area deserving further exploration. This paper aims to provide a complete expository of quantum communication, describing the principles that govern it, which is quite different from classical communication. However, the paper also reflects on how the industrialization of quantum communication was achieved and examples of funded projects that were developed. Quantum communication is then considered in the context of 6G networks, IoT, government, and defense to show the typical use of quantum communication in future information processing and secure communication domains. The paper aims to integrate the most recent developments, difficulties, and future outlook of the subject, hence serving as a thorough manual for researchers and practitioners operating in a complicated landscape of quantum communication technologies.
In the 21st century, the world is full of rapid changes and constant development of technology. The modern rhythm of life requires innovations and revolutionary solutions that would ensure efficiency, safety, and stability in various spheres of activity. In this context, quantum technologies come to the fore and provide unparalleled opportunities to transform our world. The relevance of research and study of quantum technologies is growing every day. They already today have the potential to change our understanding of cleaning processes, cryptography, telecommunications, medicine, and other industries. Understanding the principles of quantum physics and the possibilities of their implementation in practical application becomes necessary due to the rapid progress of scientific research in this area. This research paper aims to review the literature and analyze the prospects and applications of quantum technologies. It will be a valuable source of information for researchers, scientists, engineers, and all those interested in the future development of these advanced technologies. In this framework, the main principles of quantum physics will be developed; its advantages differ from classical technologies and demonstrative application in various fields. Current challenges and obstacles to the introduction of quantum technologies, as well as ways to overcome them, will also be highlighted. It is expected that this work will help readers gain a deeper understanding of the essence of quantum technologies and their impact on the modern world. It will encourage further research, contributing to the development and improvement of these powerful tools.
Quantum technology has garnered considerable attention for its transformative potential across various industries since the early 2000s, precipitating a surge in quantum start-ups and substantial investments worldwide. However, comprehensive research on quantum technology in industries, particularly start-ups in the quantum field, remains limited. This study analyzes a dataset of 1,200 quantum start-ups from 40 countries, specifically focusing on 430 notable active start-ups. The analysis provides a thorough perspective on the industry’s progress, including trends in growth, geographical distribution, industry categorization, and investment patterns. The study categorizes start-ups into five domains: quantum computing, communication, sensing, hardware, and software. The analysis further captures the progress made by ten prominent quantum start-ups, six major technology companies, and quantum consortia regarding their technological innovations and strategic partnerships. We provide a comparative analysis of prior research to identify current conditions and future implications validated by notable studies, focusing on key parameters such as dataset scope, geographical distribution, growth trends, industry categorization, taxonomy, main interests in quantum fields, key players, and ecosystem identification. This approach underscores the dynamic growth of the quantum industry, which will drive future advancements.
A new quantum information technology (QIT) could emerge in the future, based on current research in the fields of quantum information processing and communication1, 2, 3 (QIPC). In contrast to conventional IT, where quantum mechanics plays a support role in improving the building blocks, fundamental quantum phenomena play a central role in QIPC — information is stored, processed, and communicated according to the laws of quantum physics. This additional freedom could enable future QIT to perform tasks we will never achieve with ordinary IT. Today many people are familiar with at least the consequences of Moore’s Law — the fastest computer in the shops doubles in speed about every 18 months to two years. This exponential progress, first noted4 by Gordon Moore — cofounder and former CEO of Intel — in 1965, has continued ever since. But it cannot go on forever. Hurdles exist, for example: silicon will hit problems, with oxide thinness or track width5; new materials or even new paradigms, such as self-assembled nano-devices or molecular electronics, will be needed; lots of dollars will be required as Moore’s second law tells us that fabrication costs are also growing exponentially. However, even if the hurdles can be overcome, we will eventually run into nature.
Quantum computing technologies have become a hot topic in academia and industry receiving much attention and financial support from all sides. Building a quantum computer that can be used practically is in itself an outstanding challenge that has become the ‘new race to the moon’. Next to researchers and vendors of future computing technologies, national authorities are showing strong interest in maturing this technology due to its known potential to break many of today’s encryption techniques, which would have significant and potentially disruptive impact on our society. It is, however, quite likely that quantum computing has beneficial impact on many computational disciplines. In this article we describe our vision of future developments in scientific computing that would be enabled by the advent of software-programmable quantum computers. We thereby assume that quantum computers will form part of a hybrid accelerated computing platform like GPUs and co-processor cards do today. In particular, we address the potential of quantum algorithms to bring major breakthroughs in applied mathematics and its applications. Finally, we give several examples that demonstrate the possible impact of quantum-accelerated scientific computing on society.
It is now roughly thirty years since the incipient ideas on quantum information science was concretely formalized. Over the last three decades, there has been much development in this field, and at least one technology, namely devices for quantum cryptography, is now commercialized. Yet, the holy grail of a workable quantum computing machine still lies faraway at the horizon. In any case, it took nearly several centuries before the vacuum tubes were invented after the first mechanical calculating were constructed, and several decades later, for the transistor to bring the current computer technology to fruition. In this review, we provide a short survey of the current development and progress in quantum information science. It clearly does not do justice to the amount of work in the past thirty years. Nevertheless, despite the modest attempt, this review hopes to induce younger researchers into this exciting field.
