The Cybersecurity Guide to Governance, Risk, and Compliance

CHAPTER 29Quantum Computing: A New Frontier

“Quantum computing has the potential to disrupt the field of cybersecurity, rendering encryption obsolete. The intricate interplay of qubits exposes weaknesses, leaving digital defenses powerless against this quantum onslaught.”

Quantum computing represents an emerging paradigm in cybersecurity with potentially transformative impacts on businesses and governments. An initial understanding of quantum computing and a comparison to classical computing sets the foundation for further exploration. The connection between quantum computing and cryptography is another area of focus, outlining how quantum technologies could influence current cryptographic methods and lead to the development of quantum‐resistant cryptography. The study also delves into the geopolitical and strategic aspects of the global “quantum race” and emphasizes the need for a quantum‐ready cybersecurity framework.

QUANTUM COMPUTING – AN EMERGING PARADIGM IN CYBERSECURITY

Quantum computing, an emerging field with the potential to cause a seismic shift in information technology, operates on principles that deviate significantly from those of classical computing. This deviation begins with the unit of data. While classical computing relies on bits, each holding a value of 0 or 1, quantum computing introduces quantum bits or qubits. The revolutionary characteristic of qubits is their ability to exist in multiple states at once, a phenomenon known as superposition. Through ...
