The advancements in quantum computing and quantum cryptology have recently started to gain momentum and transformation of usable quantum technologies from dream to reality has begun to look viable. This has created an immediate requirement to comprehend quantum attacks and their cryptographic implications, which is a prerequisite obligation to design cryptographic systems resistant to current and futuristic projected quantum and conventional attacks. In this context, this paper reviews the prevalent quantum concepts and analyses their envisaged impact on various aspects of modern-day communication and information security technologies. Moreover, the paper also presents six open-problems and two conjectures, which are formulated to define prerequisite technological obligations for fully comprehending the futuristic quantum threats to contemporary communication security technologies and information assets processed through these systems. Furthermore, the paper also presents some important concepts in the form of questions and discusses some recent trends adapted in cryptographic designs to thwart quantum attacks.
