"The rapid advancement of quantum computing poses a significant threat to the cybersecurity of our increasingly digitized world. As quantum computers become more powerful and accessible, they have the potential to break many of the cryptographic algorithms that currently secure our sensitive data, financial transactions, and critical infrastructure. This looming “quantum threat” has far-reaching implications for individuals, organizations, and nation-states, as it could lead to widespread data breaches, economic disruption, and compromised national security. Despite the growing recognition of this risk, existing legal and regulatory frameworks are largely unprepared to address the unique challenges of quantum-enabled cyber threats. Moreover, the geopolitical implications of the quantum revolution are complex and multifaceted, with the potential to reshape the global balance of power and exacerbate technological inequalities. To mitigate these risks and promote quantum readiness, there is an urgent need for the international community to develop new legal frameworks and cooperative mechanisms that span technical, economic, legal, and political domains. This article provides an interdisciplinary analysis of the quantum threat to cybersecurity, examines its potential impacts across various sectors and international relations, and offers policy recommendations for developing a comprehensive global governance framework. By proactively addressing this challenge through multi-stakeholder collaboration and quantum-resistant solutions, we can work towards a more secure and resilient digital future in the face of this transformative technology.
