SEALSQ Welcomes the Official Launch of the "Year of Quantum Security 2026" and Confirms Active U.S. Deployments of Post-Quantum Semiconductor Technology

Geneva, Switzerland, Jan. 15, 2026 (GLOBE NEWSWIRE) --

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, SEALSQ Corp., a global leader in post-quantum semiconductor and cryptographic security technologies, welcomes the official launch of the "Year of Quantum Security 2026" ("YQS2026") in Washington, D.C., on January 12, 2026. The event brought together U.S. government officials, industry leaders, legal experts, and international partners and marked a call to action to address the growing risks posed by quantum computing, emphasizing the need for coordinated global strategies, timely adoption of quantum-safe technologies, and long-term planning to protect critical infrastructure and sensitive data.

The discussions in Washington reflected precisely what SEALSQ has been preparing for over the last several years: the urgent need to secure long-lived data, critical infrastructure, and emerging quantum technologies themselves against future quantum-enabled threats.

"Quantum security is not a future problem. It is a present responsibility," said Carlos Moreira, CEO of SEALSQ. "The launch of YQS2026 is a natural extension of what we are already executing in the United States via the deployment of post-quantum semiconductor-based trust anchors that are securing real-world systems in production environments."

The Year of Quantum Security 2026 marks a turning point, and for SEALSQ it confirms a trajectory already underway: protecting the world's digital foundations from the classical age through the quantum era.

Last year, SEALSQ announced a first partnership with Trusted Semiconductor Solutions (TSS) aimed at supplying US government and enterprise customers with post-quantum-ready semiconductor platforms. These include secure microcontrollers and chips embedding quantum-resistant cryptographic algorithms, hardware roots of trust that protect data, devices, and networks against harvest-now-decrypt-later attacks, as well as secure identity and authentication chips designed for long-life government applications. These technologies are already deployed in millions of devices, ensuring that sensitive data created today remains protected against the arrival of large-scale quantum computers.

SEALSQ also confirmed that its roadmap extends beyond post-quantum cryptography into the next generation of quantum-enabled infrastructure. Through its ecosystem of semiconductor manufacturing, secure element design, satellite infrastructure, and cryptographic R&D, the Company is preparing to expand its security platform to support full-fledged quantum computing environments, including the protection of quantum processors, control systems, and research environments, the secure provisioning of quantum networks and quantum-safe cloud platforms, and hardware-based protection of intellectual property, algorithms, and data pipelines. This positions SEALSQ as a bridge between today's classical digital world and tomorrow's quantum era, ensuring continuity of trust across both.

The launch of YQS2026 underscored the risks posed by fragmented national approaches and delayed planning, a message SEALSQ strongly endorses. Quantum-safe migration is a multi-year journey involving cryptographic transitions, legacy infrastructure upgrades, supply-chain trust, and the protection of sensitive data with decades-long lifespans. SEALSQ's strategy directly supports this reality by delivering hardware-anchored, quantum-resilient security that can be integrated today and remain secure well into the quantum future.

As governments and industries worldwide move from awareness to action, SEALSQ stands ready to support U.S. and international partners with technologies that secure critical infrastructure, digital identity, space and satellite systems, defense and industrial platforms, and tomorrow's quantum computing environments.
