SEALSQ (NASDAQ: LAES) unveiled the Quantum Shield QS7001, described as the industry’s first secure chip embedding NIST‑standardized post‑quantum algorithms in hardware. The chip integrates ML‑KEM (CRYSTALS‑Kyber) and ML‑DSA (CRYSTALS‑Dilithium), claims 10× performance gains, improved side‑channel resistance, and tamper protection. An official product launch is planned for mid‑November 2025, with development kits available and QVault TPM variants expected H1 2026. SEALSQ cites certifications (Common Criteria EAL5+, FIPS 140‑3), a track record of protecting 1.75 billion devices, global personalization centers, recent IC’Alps acquisition, and multiple industry partnerships supporting adoption across defense, healthcare, energy, and IoT.

SEALSQ (NASDAQ: LAES) announced the integration of French ASIC design house IC’Alps to deliver an end-to-end post-quantum semiconductor strategy covering Catalog ICs, Custom ICs, and Security IP. The combined teams will pursue a three-phase roadmap: short-term commercialization of the first PQC-standard chip, mid-term development of the QASIC (Quantum ASIC) and related security IP, and longer-term secure system solutions including Chiplet-based HSMs and pre-certified secure enclaves. The first prototype from this roadmap is expected in 2026. SEALSQ says IC’Alps brings analog, mixed-signal, RISC-V, power management, and embedded NVM expertise, preferred partnerships with six leading foundries, and multiple quality and security certifications.
