Signal NIST post-quantum standards and Spain's Quantum Spain and national quantum strategy

Summary

The report describes international work already under way on encryption standards for the quantum computing era. International bodies such as the US National Institute of Standards and Technology are driving a new cybersecurity framework. Projects such as Open QKD and PROMETHEUS bring together academic, industrial and government efforts to set open and secure standards for the post-quantum age. In Spain, initiatives such as the Quantum Spain project and the Spanish Quantum Technologies Strategy 2025 to 2030 show that this path will be a core pillar of a digital future already under construction. These moves stem from concern that quantum computers could undermine the mathematical difficulty on which current encryption relies. The report sees the transition as especially urgent in finance, defence and health, where data must stay confidential for long periods.
