Quantum computing is fundamentally changing our approach to cybersecurity and cryptography cryptography . New types of computation opportunities and approaches are introduced by quantum computation which is discussed in this paper as well as the shift towards quantum secure security models including encryption for critical infrastructure and cloud systems. The holism of how quantum computing quantum computing affects quantum resistant infrastructures is assessed from the application level down to the hardware level. The paper is devoted to describing the measures that have to be taken, in the quantum tech age, to counter threats and disaster scenarios related to quantum technologies quantum technologies . The study raises concerns about the lack of well thought out and coordinated approaches to building reliable and quantum-safe systems. A detailed defense strategy does not only offer a solution for handling cyber threats cyber threats that emanate from the installation of quantum technologies but also offers the relevant stakeholders how to guide the management of the infrastructure and formulation of policies.
