The theory of classical universal computation was laid down in 1936, was implemented within a decade, became commercial within another decade, and dominated the world's economy half a century later. This success story relied on the progress in technology. As computers become faster they must become smaller. The history of computer technology has involved a sequence of changes from one type of physical realisation to another, with smaller and smaller components. The unavoidable step to the quantum level will be one in this sequence; but it promises something more exciting as well. It can support entirely new modes of computation that do not have classical analogues. There is so much potential in this fundamentally new way of harnessing nature that it appears as though the age of computation has not yet even begun!
2025 is the year UNESCO selected to celebrate 100 years of this novel science, quantum mechanics, based on Heisenberg’s “uncertainty principle” discovery. However, quantum mechanics began with the discovery of quantum packets of energy emission formulated by the German physicist Max Planck, and it incorporated additional discoveries and principles from Albert Einstein, Niels Bohr, Heisenberg, Pauli, de Broglie, and many others in the early 1900s. Since then, many advancements and breakthroughs have been made. Such scientific contributions have influenced the culture and technology of humanity from the 20th century onwards, with the first quantum revolutions bringing innovations in technology and engineering, including the omnipresent light amplification by stimulated emission of radiation (Laser), magnetic resonance imaging (MRI), microprocessor manufacturing and design for computers and nuclear energy. Thus, at the beginning of the Second Quantum Revolution in the 21st century, amid a new wave of novel quantum technologies promising to create the 5th Industrial Revolution and transform humanity, a brief history of these marvellous sciences is condensed, connecting the wonders of the new quantum technogenesis that is being forged, linking its past with classical mechanics and also with novel relativistic mechanics. Understanding these developments highlights the significance of quantum technologies shaping our future and what lies ahead for us. This article explores technologies that are presently under research and development (R&D) in the quantum physics realm, including quantum computing, quantum cryptography, quantum sensing and metrology, and quantum simulation. It also discusses emerging careers in the quantum field and the unresolved mysteries that continue to challenge scientists. The discussion follows the ancient griot tradition of storytelling, a method that the distinguished physicist, great professor, and Nobel laureate Richard Feynman encouraged us to use to explain complex scientific ideas.
The current state of the art in space systems would not be possible without the advances in our understanding of matter and light at the atomic level provided by quantum theory. This triumph of 20th century physics provides the foundation for most of the components employed in satellites from integrated circuits, solar cells, atomic clocks, and advanced materials. Over the past 25 years a new understanding of the relationship between quantum theory, theory and security, and computing has raised the possibility of exploiting \quantum information for computing and secure encryption key generation. The eld of quantum science exploits quantum states for processing and security applications. The power of quantum derives from the quantum nature of matter that allow algorithms with exponential speed-up when compared to the best-known classical algorithms. Quantum Key Distribution involves using quantum states, typically encoded into the phase or polarization of photons, to securely share the bits to be used to construct an encryption key. The theoretical security of quantum key distribution rests on the physical laws of quantum theory, unlike classical cryptography that relies on assumptions about the computational complexity of certain mathematical problems. In this paper we survey the state of quantum science and technology, summarizing the basic features of quantum processing and key distribution. We describe the potential for quantum computing and key distribution to support future NSS applications and missions, for both the ground and space segments. We conclude with a discussion of the current challenges with advancing quantum technology to meet these future needs.
Information as accessed by the human mind, and the myriad ways of processing it, is what has set humankind apart in the animal world. The ability to use the physical systems around us to encode and then to process information has been evolving in leaps and bounds ever since the dawn of our race! The earliest form of computation was probably in the form of account-keeping by counting pebbles or on the fingers. This developed into the abacus, writing symbols, the computing machine, and now, a laptop or a supercomputer: everywhere we represent information by means of a physical system, and perform manipulations on that system to process the information in many desired ways, including communication. The stress here is on the realization that the basis of information is a physical system. The more advanced that system is and the set of rules it functions on, the more capable our means of information processing and communication. When the underlying physical system used for encoding and processing information is a quantum system, we have quantum information processing.
Abstract Design and development of new drug molecules are essential for the survival of human society. New drugs are designed for therapeutic purposes to combat new diseases. Besides treating new diseases, new drug development is also needed to treat pre‐existing diseases more effectively and reduce the existing drugs' side effects. The design of drugs involves several steps, from the discovery of the drug molecule to its commercialization in the market. One of the most critical steps in drug design is to find the molecular interactions between the target (infected) molecule and the drug molecule. Several complex chemical equations need to be solved to determine the molecular interactions. In the late 20th Century, the advancement of computational technologies has made the solution of chemical equations relatively easier and faster. Moreover, the design of drug molecules involves multi‐criteria optimization. Classical computational methodologies have been used for drug design since the end of the 20th Century. However, nowadays, more advanced computational methodologies are inevitable in designing drugs for new diseases and drugs with fewer side effects. In this context, the quantum computing paradigm has proved beneficial in drug design due to its advanced computational capabilities. This paper presents a state‐of‐the‐art comprehensive review of the quantum computing‐based methodologies involved in drug design. A comparative study is made about the different quantum‐aided drug design methods, stating each methodology's merits and demerits. The review work presented in this manuscript will help new researchers assess the present state‐of‐the‐art concept of quantum‐based drug design.
