Abstract: Quantum computing is a modern calculation method that is based on the science of quantum mechanics. These phenomena include the bizarre behavior of particles at the atomic and subatomic levels, and the way that these particles can be in multiple states simultaneously. The field of computer science is a great mix of physics, math, and information theory. This technology provides high computing power, low power consumption, and exponential speed by controlling the behavior of small physical objects, such as atoms. Atoms, electrons, photons, etc. are all elements of the physical world. We would like to introduce the basics of quantum computing, and some of the ideas behind it. This article begins with the origins of the classical computer and discusses all the improvements and transformations that have been made due to its limitations thus far, then moves on to the basic operations of quantum computing and results in quantum properties such as superposition, entanglement, and interference.
Quantum computing is a contemporary method of computation that follows the concepts of quantum mechanics. This technology is a wonderful amalgamation of physics, mathematics, computer science, and information technology. This technology imparts towering computing capacity, lessened energy demand, and mounting speed on top of conventional machines. This is accomplished by having a control on the behavior of tiny physical matter such as atoms and electrons. This chapter gives a sneak peek into the world of quantum computing and its fundamental concepts. This work also discusses the conventional mechanism of computing and augmentation and transfiguration happened due to constraints in the existing machines. After discussing this, the flow of work moves to discussion of the basic work mechanism and properties of quantum computing. This work also uncovers the hardware and software requirements, its significance, and favorable and unfavorable outcomes. This study certainly gives a deep insight into the power of this new arising technology in this competitive world.
Why quantum computing? As we all know very well, conventional (electronic) computers have enormous power which, moreover, is constantly increasing. With their help gigantic quantities of data can be handled and evaluated. This is of crucial importance, for instance, in modern high energy physics experiments. On the other hand, computers can be used to model very complex systems with the aim of predicting, for example, future developments in our environment, notably climatic changes. Thanks to their incredible speed computers are, of course, destined to treat mathematical problems for which specific algorithms exist very efficiently. To mention a simple example, the digits of π are readily evaluated up to a very high order. Last, but not least, their potential to solve differential equations numerically, even when they are nonlinear, makes computers indispensable in modern research. So, one might ask, is there any reason to look for fundamentally new ways of computing as they are seemingly offered by quantum processes? What advantages can be expected when the laws of quantum mechanics, rather than those of classical physics, are exploited for computation? Two answers were given: first, the simulation of complex quantum systems on classical computers meets serious difficulties that might be overcome with the help of quantum computers. This idea was suggested in 1982 by R. Feynman, and in the 1990s it was indeed shown by several groups of researchers that quantum mechanical systems for which no efficient simulation on a classical computer is known can be efficiently simulated on a quantum computer.
Applying quantum artificial intelligence (QAI) to protect healthcare systems includes several technologies that improve data security and protect against threats. The chapter emphasizes the need for advanced cybersecurity techniques in healthcare, integrating QAI to protect sensitive data. Traditional defense frameworks are insufficient, and QAI, a combination of quantum computing and artificial intelligence (AI), is needed to address the complexities of cyber threats and establish enduring cybersecurity frameworks. The chapter describes the cybersecurity problems of the healthcare sector. Digital transformation has revolutionized the healthcare sector by introducing electronic health records, connected medical devices, and telemedicine which now provide a bigger target for cyber adversaries. The delicacy of health data is the reason why it is the major target of ransomware, data breaches, and other hacking techniques. As the threats grow more complicated, traditional security solutions may become less effective. This chapter presents QAI as a novel technique for taking care of these issues using the incredible computational power of quantum computing combined with the pattern recognition and decision-making skills of AI. Furthermore, the chapter reviews the field of quantum resistance, which is defined as the capability of algorithms to deliver secure encryption even in the face of quantum computers; under this context, the chapter presents lattice-based and hash-based cryptography as critical to protecting healthcare data from future quantum cyberattacks. These encryption techniques protect against threats from quantum computing and most of today’s common encryption methods such as the Rivest-Shamir-Adleman (RSA) and Elliptic Curve Cryptography (ECC) are vulnerable to breakage by quantum machines.
