ABSTRACT The paper examines the rise of quantum computing and its implications for cybersecurity. Quantum computers, unlike classical ones, use principles of quantum mechanics, such as superposition and entanglement, to solve complex problems exponentially faster. This poses a threat to existing cryptographic systems, especially those based on public-key encryption like RSA and ECC, which could be vulnerable to quantum algorithms such as Shor’s algorithm. The document highlights the potential for quantum computing to break current encryption methods, putting sensitive data at risk from cybercriminals. To mitigate these risks, researchers are developing post-quantum cryptography and exploring quantum-resistant security measures, such as Quantum Key Distribution (QKD), to protect data in a future quantum-powered landscape. The paper emphasizes the urgency of updating encryption and cybersecurity strategies to prepare for the impending "quantum era." keywords Quantum computer Cyber security Cryptography Algorithm Digital signature Post-quantum cryptography Quantum key distribution Cyber attack Digital infrastructure Quantum mechanism Legacy systems Quantum era
