Managing Cyber Security with Quantum Techniques

Recent advancements in quantum information theory and quantum computation intend the possibilities of breaking the existing classical cryptographic systems. To mitigate these kinds of threats with quantum computers we need some advanced quantum-based cryptographic systems. The research orientation towards this is tremendous in recent years, and many excellent approaches have been reported. In this article, we discuss the probable approaches of the quantum cryptographic systems from implementation point of views to handle the post-quantum cryptographic attacks.
