SEALSQ and Quobly have entered into a $5 million agreement to bolster the security of Quobly's silicon-based quantum computing platform with post-quantum security technologies. This partnership expansion will integrate secure semiconductors, Root-of-Trust technologies, and post-quantum cryptography into Quobly's systems, enhancing the security of next-generation quantum infrastructure. The collaboration aims to support the development of a European quantum computing ecosystem, with a focus on securing quantum systems against potential threats. As quantum computing advances, the need for post-quantum cryptography becomes increasingly urgent, with the timeline for cryptographic migration narrowing1. This agreement underscores the importance of proactive security measures in the face of emerging quantum technologies. The integration of post-quantum security technologies will be crucial for protecting sensitive information and preventing potential breaches, making this partnership a significant step forward in the development of secure quantum computing systems, and thus, practitioners should prioritize post-quantum cryptography planning to ensure the long-term security of their systems.
