Quantum computing is an advanced computational paradigm that leverages principles of quantum mechanics, including superposition, entanglement, and interference, to process information more efficiently than classical systems [1][2]. Unlike classical bits, qubits can exist in multiple states simultaneously, enabling exponential computational capabilities for complex problem-solving. Since its theoretical foundations proposed by Richard Feynman and further developed by David Deutsch, quantum computing has progressed into an active research and industrial domain [2][3]. This paper presents an overview of the core concepts of quantum computation, technological evolution, and key algorithms such as Shor’s and Grover’s, which demonstrate significant computational advantages [9][10]. It also explores major application areas including cryptography, healthcare, artificial intelligence, and optimization, while addressing critical challenges such as decoherence, error correction, and scalability [5][6]. The study highlights future prospects, emphasizing the potential of quantum computing to transform scientific and industrial domains [12][15].

Quantum computing is a developing field with the prospective to revolutionize the current advanced computing, it represents a fundamental shift from classical computing principles towards superposition, entanglement, and quantum interference, which are quantum mechanical principles. By using these distinctive principals and properties of quantum mechanics, ‘Quantum Computing’ processes information in the ways that are principally different from classical computers. This paper examines the fundamental concepts of quantum computing, its current and potential diverse applications, and the effects it has on cybersecurity. As quantum computing continues to advance, it proposes both forecasts and challenges, especially in cryptography, data protection, and security systems. This review paper focusses to discuss a comprehensive understanding of the junction between quantum computing and cybersecurity. It also point-outs the risks to current encryption theory and the new quantum-safe cryptography practices.
