Geneva, Switzerland, March 4, 2026 -- 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 it is ready to offer its Quantum-Resilient Vertical Security Stack to protect companies developing quantum computers and quantum computing infrastructures.
As the global race to build practical quantum computers accelerates, securing the systems that control and operate these powerful machines has become a critical challenge. While quantum computing promises breakthroughs in fields such as materials science, artificial intelligence, pharmaceuticals, and financial modeling, it also introduces new cybersecurity risks that require next-generation protection mechanisms embedded directly into hardware and system architectures.
SEALSQ can address this challenge through comprehensive end-to-end security architecture, spanning from Root of Trust, PKI technology with post quantum certificates embedded in quantum resistant secure semiconductors, to identity management. This vertical quantum-proof approach could enable quantum computing developers to secure the entire lifecycle of their systems, from quantum processor control electronics to cloud orchestration platforms.
By integrating hardware Root of Trust and post-quantum cryptography at the silicon level, SEALSQ enables quantum computing developers to create secure-by-design architectures, avoiding the risks and inefficiencies associated with retrofitting security into existing IP blocks.
As quantum computing transitions from research laboratories to industrial and commercial deployment, the security of quantum systems themselves becomes a critical engineering priority. Quantum processors, cryogenic controllers, and cloud-accessible quantum platforms introduce novel attack surfaces that traditional cryptographic methods cannot adequately protect.
SEALSQ addresses this challenge directly: by embedding post-quantum cryptography and hardware-anchored Root-of-Trust at the semiconductor level, we could ensure that quantum computing systems are designed to be both powerful and provably secure from the earliest stages of their architecture.
SEALSQ will provide four integrated service modules covering the complete quantum computing security stack, from hardware identity through cloud-accessible quantum platforms.
SEALSQ secure elements and TPM technologies can provide hardware-anchored identity and authentication for quantum processors, cryogenic controllers, and supporting infrastructure.
SEALSQ can deploy NIST-standardized PQC cryptographic stacks in August 2024 designed to protect systems against future quantum-enabled cyberattacks.
Quantum processors depend on classical electronics for control, orchestration, and error correction. SEALSQ can integrate secure ASIC architectures directly into quantum hardware designs.
As quantum computing will move toward cloud deployment models, SEALSQ could also provide the identity, authorization, and communication security layer for Quantum Computing as a Service (QCaaS) platforms.
“Quantum computers will redefine the limits of computing, but they will also redefine cybersecurity risks,” said Carlos Creus Moreira, CEO of SEALSQ. “Organizations developing quantum technologies must ensure their infrastructures are built on trusted security foundations. SEALSQ is ready to provide a complete vertical stack, from silicon Root of Trust to QBit-level protection, designed to secure the entire quantum computing ecosystem.”
SEALSQ’s cybersecurity technologies are already deployed in more than 1.7 billion devices worldwide, securing critical infrastructure, IoT systems, healthcare platforms, and government networks. By extending its post-quantum semiconductor and cryptographic capabilities to the quantum computing sector, SEALSQ aims to become a strategic cybersecurity partner for companies building the next generation of computing platforms.
As quantum technologies continue to evolve, SEALSQ’s mission is to ensure that the quantum era is built on secure, trusted, and resilient digital foundations.
