On January 12, 2026, SEALSQ Corp welcomed the launch of the “Year of Quantum Security 2026” in Washington, D.C., an industry-wide initiative that convened over 150 U.S. government officials, legal experts, international partners and technology leaders to address the accelerating threat posed by large-scale quantum computers. SEALSQ’s CEO Carlos Moreira highlighted the company’s existing post-quantum semiconductor trust anchors, which have been integrated into production environments across the U.S. over the past year. These secure microcontrollers and identity chips—developed in partnership with Trusted Semiconductor Solutions—are embedded in over three million devices used in critical infrastructure, defense communications and commercial networks to guard against harvest-now-decrypt-later attacks.

SEALSQ has entered exclusive negotiations under a non-binding memorandum of understanding to invest approximately $200 million in Quobly SAS, a French quantum computing firm specializing in silicon-based processors. The multi-stage transaction contemplates an initial minority investment followed by acquisition of a majority stake, combining SEALSQ’s post-quantum cryptographic expertise with Quobly’s hardware capabilities. This deal builds on a November 2025 collaboration agreement and aims to co-develop secure-by-design quantum systems, leveraging SEALSQ’s roadmap to extend hardware-anchored security into emerging quantum infrastructures, including protected provisioning of quantum networks and cloud platforms.
