PART I: WHY QUANTUM IS A GOVERNANCE CRISIS, NOT A LAB EXPERIMENT

This part establishes the fundamental reframing required to understand quantum computing in a regulated, enterprise, and societal context. Its purpose is to move the reader away from the common misconception that quantum computing is a distant technological curiosity and toward the recognition that it represents a present-day governance and risk challenge.

The chapters in this part demonstrate that quantum computing does not introduce a new type of cyberattack, but rather invalidates long-standing assumptions about cryptography, trust, and time. By examining systemic risk, the collapse of strong encryption, the strategy of harvest now, decrypt later, and the breakdown of cryptographic proof, this part shows that quantum risk is not localized, detectable, or reversible. It accumulates silently and materializes retroactively.

This part is particularly relevant for executives, board members, regulators, and risk officers, because it translates technical disruption into governance consequences. It explains why delayed cryptographic failure can still constitute present negligence, why long-term confidentiality obligations are already under threat, and why trust mechanisms such as digital signatures and audit trails are becoming fragile.
