SEALSQ Deploys Post-Quantum Chips in Millions of Devices Worldwide

SEALSQ Corp. has deployed post-quantum chips in millions of devices worldwide. These semiconductors and cryptographic technologies include secure microcontrollers embedding quantum-resistant algorithms and hardware roots of trust. This deployment addresses the urgent need to protect long-lived data and critical infrastructure against future quantum computing threats.

YQS2026 Launch Highlights Quantum Security Urgency

The YQS2026 launch in Washington, D.C. signaled a critical shift in focus toward proactive quantum security measures, aligning with SEALSQ’s multi-year preparation for this eventuality. Company CEO Carlos Moreira emphasized that quantum security is an immediate concern, not a distant threat, and that SEALSQ is already deploying post-quantum semiconductors as trust anchors in live systems. This initiative addresses the rising risks of “harvest-now-decrypt-later” attacks, protecting data created today from future decryption by quantum computers. SEALSQ’s established partnership with Trusted Semiconductor Solutions highlights its commitment to supplying post-quantum platforms to U.S. government and enterprise clients.

These platforms include secure microcontrollers with quantum-resistant cryptography, designed to secure data, devices, and networks—demonstrating SEALSQ’s move beyond cryptography to encompass the next generation of quantum-enabled infrastructure, including protection for quantum processors themselves. Millions of devices already incorporate these technologies, ensuring long-term data protection.

SEALSQ’s Post-Quantum Semiconductor & Cryptographic Solutions

SEALSQ develops post-quantum semiconductor solutions, including secure microcontrollers and chips, embedding quantum-resistant cryptographic algorithms. These hardware roots of trust aim to defend against “harvest-now-decrypt-later” attacks, safeguarding data, devices, and networks. The company’s technologies are already integrated into millions of devices, offering long-term data protection as quantum computing capabilities advance. Their ecosystem spans semiconductor manufacturing, secure element design, and cryptographic research, enabling support for full-fledged quantum computing environments. This comprehensive approach positions SEALSQ to bridge classical and quantum digital worlds, maintaining trust throughout the transition.

Protecting Infrastructure: From Classical to Quantum Eras

Protecting infrastructure requires a long-term strategy, as SEALSQ delivers hardware-anchored security designed to transition systems from today’s classical digital world into the quantum era. This involves cryptographic transitions, infrastructure upgrades, and securing data with decades-long lifespans against future threats. The company’s semiconductors embed quantum-resistant algorithms, offering protection against “harvest-now-decrypt-later” attacks and establishing hardware roots of trust for networks and devices. SEALSQ’s roadmap extends beyond current post-quantum cryptography, preparing for full-fledged quantum computing environments. They are developing solutions to protect quantum processors, networks, and research environments, alongside secure provisioning for quantum-safe cloud platforms. This expansion leverages their existing ecosystem of semiconductor manufacturing and cryptographic research to ensure continued trust as computing evolves.
