Quantum computing, a novel branch of technology based on quantum theory, processes information in ways beyond the capabilities of classical computers. Traditional computers use binary digits [bits], but quantum computers use quantum binary digits [qubits] that can exist in multiple states simultaneously. Since developing the first two-qubit quantum computer in 1998, the quantum computing field has experienced rapid growth.

Cryptographic algorithms such as RSA and ECC, essential for internet security, rely on the difficulty of complex math problems that classical computers can’t solve. However, the advancement of quantum technology threatens these encryption systems. Algorithms, such as Shor’s, leverage the power of quantum machines to factor large numbers, a task challenging for classical computers.

Acknowledging this threat, it is important to develop and implement quantum-resistant cryptography to safeguard communication, financial systems, and national security. This study covers the past, present, and future of quantum computing and cybersecurity and their increasingly connected roles. It provides a detailed history of both fields, explores the challenges posed by quantum computing to traditional cryptographic methods, and discusses the development of new, robust cryptographic solutions to ensure security in a future where quantum computing is prevalent.
