The US quantum resilience clock has become operational, marking a significant milestone in the country's efforts to prepare for the potential risks associated with quantum computing. This development is particularly notable in light of Executive Order 14412, which has introduced deadlines for addressing quantum-related threats. A common misconception is that quantum attacks will only begin once a powerful quantum computer is available, but in reality, the risk starts much earlier. As a result, organizations must take proactive steps to enhance their quantum resilience. The operationalization of the quantum resilience clock underscores the importance of prompt action, as the clock is now ticking towards a future where quantum computers could potentially compromise certain types of encryption1. This matters to practitioners because it highlights the need to prioritize quantum risk mitigation strategies, such as migrating to quantum-resistant cryptography, to ensure the long-term security of their systems and data.
