-Quantum computer is no longer a hypothetical idea. It is the world's most important technology and there is a race among countries to get supremacy in quantum technology. It is the technology that will reduce the computing time from years to hours or even minutes. The power of quantum computing will be a great support for the scientific community. However, it raises serious threats to cybersecurity. Theoretically, all the cryptography algorithms are vulnerable to attack. The practical quantum computers, when available with millions of qubits capacity, will be able to break nearly all modern public-key cryptographic systems. Before the quantum computers arrive with sufficient ‘qubit’ capacity, we must be ready with quantum-safe cryptographic algorithms, tools, techniques, and deployment strategies to protect the ICT infrastructure. This paper discusses in detail the global effort for the design, development, and standardization of various quantum-safe cryptography algorithms along with the performance analysis of some of the potential quantum-safe algorithms. Most quantum-safe algorithms need more CPU cycles, higher runtime memory, and a large key size. The objective of the paper is to analyze the feasibility of the various quantum-safe cryptography algorithms.

It emphasizes the urgency of preparing for the quantum era while acknowledging the complexities involved in implementing quantum-resistant measures across global networks. This comprehensive overview provides insights into the evolving landscape of cybersecurity in the face of advancing quantum technologies and underscores the critical need for proactive strategies to safeguard digital infrastructure in the coming quantum age.
Quantum computing is rapidly advancing, with significant implications for cybersecurity. While it holds the potential to revolutionize computation, it also poses a threat to current cryptographic systems. This tutorial introduces the fundamentals of quantum computing, explores the state of quantum software engineering, and examines the impact of quantum advancements on cryptography and cybersecurity. It will also discuss post-quantum cryptography (PQC) and strategies for transitioning to quantum-resistant cryptographic systems. The session will provide both theoretical insights and practical guidance for cybersecurity professionals preparing for dependable systems and networks in a post-quantum future.
