SEALSQ to launch Quantum Shield QS7001 mid-November, pioneering Post-Quantum Cryptography for Cryptocurrencies and Beyond

Geneva, Switzerland, Sept. 19, 2025 (GLOBE NEWSWIRE) --

Geneva, Switzerland, September 19, 2025 -- SEALSQ Corp (NASDAQ: LAES) ("SEALSQ" or "Company"), a company that focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products, today announced plans to launch the Quantum Shield QS7001 in mid-November 2025. 

Positioned to be the world’s first¹ secure chip to embed NIST-standardized quantum-resistant algorithms ML-KEM (CRYSTALS-Kyber) and ML-DSA (CRYSTALS-Dilithium) at the hardware level, the Quantum Shield QS7001 aims to secure critical applications such as cryptocurrency transactions, but also defense systems, healthcare infrastructure, and IoT devices against future quantum computing threats.

As quantum computing advances toward “Q-Day”—when quantum computers could break traditional encryption like elliptic curve cryptography (ECC)—the QS7001 addresses vulnerabilities in systems such as Bitcoin and other blockchains. Current ECC-based algorithms, including ECDSA, are susceptible to quantum attacks that could compromise public keys and expose funds.

The Quantum Shield QS7001 integrates lattice-based, quantum-resistant cryptography to provide secure key storage, efficient signing, and key exchange operations, optimized for hardware wallets, cold storage, and IoT devices. It also offers a migration framework with hybrid cryptography and tools to transition existing systems to quantum-safe standards with minimal disruption. The chip is launched as an open hardware platform to host personalized customer firmware, enabling full flexibility for all kinds of applications. SEALSQ also plans to launch a Trusted Platform Module version, the QVault TPM, in H1 2026.

While its very few competitors only integrate post-quantum cryptography through hardware accelerators that support PQC via software implementations, SEALSQ's QS7001 embeds these quantum-resistant algorithms directly at the hardware level. This approach delivers enhanced efficiency (10X faster), side-channel protection, and tamper resistance without relying on software layers, aiming to provide a more robust foundation for long-term security in high-stakes environments.

“The Quantum Shield QS7001 is a pivotal advancement in preparing for the quantum era,” said Carlos Moreira, CEO of SEALSQ. “Our goal is to deliver robust, hardware-based security to protect cryptocurrencies, defense, healthcare, and IoT applications from emerging quantum threats, ensuring trust and resilience.”

The chip will be unveiled at the IQT Quantum+AI 2025 event in New York City on October 20, 2025, where Carlos Moreira will deliver the opening keynote, “AI Meets Quantum: Building Unbreakable Post-Quantum Security.” The first commercial development kits for the QS7001 will be available for purchase in November 2025, enabling customers to start integrating this cutting-edge technology into their solutions.

With a track record of securing over 1.75 billion devices worldwide, SEALSQ continues to lead in quantum-resistant innovation. The recent launch of SEALQUANTUM.com Lab supports organizations transitioning to quantum-safe encryption, while partnerships, such as with Hedera, highlight SEALSQ’s commitment to advancing secure solutions for IoT, banking, and automotive sectors.
