SEALSQ and Quantix to deploy post-quantum semiconductor centre

SEALSQ announced a definitive agreement with Quantix to develop and deploy Spain's first post-quantum semiconductor personalisation centre

SEALSQ announced a definitive agreement with Quantix Edge Security to develop and deploy Spain’s first post-quantum semiconductor personalisation centre in the region of Murcia.

This agreement, marking a key milestone in the Quantix Edge Security project previously announced in June 2024, is expected to generate $25 million of revenue over the next three years with recognition likely to be milestone-based during the course of the project. SEALSQ anticipates the project will begin in H1 2026 and expects project milestones will occur regularly over the life of the project, creating an even spread of revneue.

This development is aligned with the Spanish government’s national strategy to strengthen sovereignty in critical sectors such as semiconductors and cybersecurity. In September 2025, the government announced a €19.6 million public investment in Quantix, projected to deliver €793 million in economic impact to Murcia over the next five years. The new centre will reinforce Spain’s role as a European hub for post-quantum and cybersecurity-focused semiconductor innovation.

SEALSQ plans to accelerate commercialisation by distributing its post-quantum semiconductors through Quantix beginning in 2026 while the Murcia facilityy remains under construction. This strategy will enable early adoption of SEALSQ’s quantum-resistant technologies and supports its $170 million pipeline of potential revenue as part of its wider quantum roadmap.

It’s also planning to launch the QUantum Shield QS7001 in mid-November 2025, the world’s first secure chip to embed NIST-standardised quantum-resistant algorithms ML-KEM (CRYSTALS-Kyber) and ML-DSA (CRYSTALS-Dilithium) at the hardware level. The QS7001 will provide robust protection for critical applications such as cryptocurrency and blockchain infrastructures, defence and aerospace systems, healthcare platforms, and IoT ecosystems.

The QS7001 delivers secure key storage, post-quantum signing, and hybrid migration frameworks that enable transitions from RSA/ECC to quantum-secure cryptography.
