Abstract

Fast data and growing artificial intelligence have brought traditional computer infrastructures to their limits. They expose inherent limitations in processing speed, energy efficiency, and scalability. In the face of nearing physical barriers with Moore's Law and memory bottlenecks plaguing traditional von Neumann architectures, quantum computing offers a completely new way of leveraging principles such as superposition and entanglement to redefine computation possibilities. This review is concerned with addressing how quantum computing stands to do that foundational AI and big data challenges, from accelerating extremely complex optimization tasks to enabling very secure, real-time analytics. These topics include basic principles of quantum mechanics, the basis of qubits and quantum circuits; updates in quantum algorithms (such as Grover's search, quantum annealing); and hybrid classical-quantum systems that serve as pathways through technological gaps. The paper suggests major applications of transformative nature in some of the higher-impact domains: quantum-accelerated drug discovery for health, portfolio optimization in finance, and quantum-secured communication infrastructures to guard the IoT. Case studies present early successes on quantum machine learning models improving diagnostic accuracy and annealing-based traffic optimization for urban congestion. Decoherence, error-prone devices, as well as low software ecosystems are conspiring against the actual roadways to practical quantum advantages. Future progress is dependent on the innovative development of error-corrected qubits, scalable algorithms, as well as interdisciplinary collaboration. While universal quantum supremacy remains while unreached, this coming decade promises a series of developments toward applied, specific applications that will place quantum computing as an added force among the classical systems. This review tries to project both sides of the likely potential of the space, obstacles, and path, paving the way for the researcher to find their foot in the continually progressing quantum-AI terrain.

Quantum computing has emerged as a transformative computational paradigm capable of addressing limitations increasingly encountered by classical computing systems as Moore’s law approaches physical and economic constraints. By leveraging quantum mechanical principles such as superposition, entanglement, and interference, quantum systems offer the potential for significant computational advantages in solving complex problems that are currently infeasible for conventional architectures. This review critically synthesizes recent advances in quantum computing by examining foundational principles, major algorithmic breakthroughs, evolving hardware platforms, and interdisciplinary real-world applications. A structured narrative literature review was conducted using major scientific databases, including PubMed, IEEE Xplore, Nature, ScienceDirect, and arXiv, with emphasis on peer-reviewed studies, landmark foundational research, and major industry developments published between 2018 and 2026. Key findings indicate substantial progress in superconducting, trapped ion, photonic, and topological quantum systems, alongside innovations in algorithms such as Shor’s, Grover’s, variational quantum methods, and quantum machine learning. Despite these advancements, major challenges including decoherence, noise, scalability limitations, and fault-tolerant error correction remain substantial barriers to commercial maturity. Future implications suggest quantum computing may profoundly influence artificial intelligence, cybersecurity, optimization, molecular simulation, and scientific discovery, particularly through hybrid classical-quantum systems and cloud-based democratization. Although practical deployment remains transitional, quantum computing is positioned to become a foundational technology with broad scientific, industrial, and societal implications.

Quantum computing is poised to revolutionize the future of advanced computational systems, offering unprecedented speed and efficiency for solving complex problems that are beyond the capabilities of classical computers. Traditional computational models, based on bits representing either a 0 or 1, are approaching their physical and performance limits. Quantum computers, however, leverage the principles of quantum mechanics—specifically, superposition and entanglement—to operate on quantum bits, or qubits, which can exist in multiple states simultaneously. This capability allows quantum systems to process vast amounts of data in parallel, potentially solving problems in seconds that would take classical systems millions of years. As the demands on computational systems grow in fields like cryptography, artificial intelligence (AI), drug discovery, and materials science, quantum computing offers solutions that can overcome the bottlenecks faced by classical computing architectures. This paper explores the foundational principles of quantum computing, its advantages over classical systems, and its potential applications in various industries. Additionally, we analyze the current challenges that quantum computing faces, such as error rates, quantum decoherence, and hardware scalability. We also consider the future trajectory of quantum computing, including the potential for quantum supremacy and the development of hybrid quantum-classical systems. Although quantum computing is still in its nascent stages, with practical quantum computers requiring further advancements in qubit coherence and error correction, its future impact on computational systems is undeniable. This paper aims to provide a comprehensive review of how quantum computing is shaping the future of computational systems, detailing the technologies, applications, and challenges ahead. With continuous technological advancements, quantum computing has the potential to redefine global industries, solve previously unsolvable problems, and fundamentally alter our understanding of computation in the coming decades.
