SEALSQ Plans Swiss Post-Quantum Semiconductor Center

SEALSQ, WISeKey, and the Republic and Canton of Jura have signed a memorandum of understanding (MoU) to explore establishing a Post-Quantum Semiconductor and Cybersecurity Center in Switzerland. SEALSQ manufactures post-quantum chips and PKI hardware, whereas its parent company, WISeKey, specializes in cybersecurity and IoT.

Jura, a Swiss canton, would host the facility and serve as a catalyst for its development. For those in the quantum-security field, this plan signifies the potential for sovereign capacity to produce and provision chips with post-quantum cryptography within Switzerland.

MoU Details

As an MoU, the agreement indicates an intent to cooperate rather than a firm commitment of funds or a construction timeline. The companies project an estimated investment of CHF 40 to 60 million over six years for the proposed center. The envisioned work includes semiconductor personalization, testing, secure provisioning, and post-quantum technology development, with ASIC design capabilities added over time.

Central to this initiative is SEALSQ’s QS7001 Quantum Shield, a secure semiconductor designed to implement NIST-standardized post-quantum algorithms like ML-KEM and ML-DSA. The companies anticipate creating approximately 40 direct jobs within two years, growing to 150 by year five, and over 250 by year eight. 

At least 60% of these positions are expected to be filled by Jura residents.

The Need for Swiss Post-Quantum Silicon

ML-KEM and ML-DSA are the algorithms underpinning NIST’s FIPS 203 and FIPS 204 standards, respectively, with FIPS 205 covering a hash-based signature scheme. These standards aim to address the “harvest-now-decrypt-later” problem, where adversaries collect encrypted data today to decrypt it later once sufficiently powerful quantum computers become available. 

This vulnerability is particularly critical for devices with long operational lifespans, such as those found in satellites, avionics, and secure communication systems.

Though the QS7001 run standardized algorithms, this is distinct from formal certification. The release does not mention FIPS 140-3 module validation or Common Criteria status for the QS7001, meaning the algorithm implementation should not be construed as a certified module.

Next Steps and Open Questions

The involved parties plan to establish a joint working group to develop a detailed business plan, select a site, structure public-private financing, and define a certification roadmap. The center will operate as a Swiss company incorporated in Jura. 

This initiative builds on the success of Quantix Edge Security, a EUR 40 million center in Murcia, Spain, which SEALSQ reported generated initial revenue in the second quarter of 2026. This endeavor focuses specifically on SEALSQ’s post-quantum hardware, differentiating it from unrelated developments such as Fujitsu’s open-sourced quantum package.
