SEALSQ to Lead EeroQ Financing Round, Accelerate CMOS-Compatible Quantum Processor Scaling
LAES•SEALSQ Corp has agreed to lead EeroQ’s next financing round, following two prior investments in December 2025 and February 2026, using its Quantum Fund to deepen its long-term “Quantum Made in USA” strategy. The company’s expanded commitment supports scaling EeroQ’s CMOS-compatible helium-based quantum processor and Chicago R&D footprint.
1. Strategic Investment and Lead Role
SEALSQ Corp has signed a new investment agreement with EeroQ, marking its third financial commitment following stakes in December 2025 and February 2026. Under the deal, SEALSQ will anchor EeroQ’s upcoming priced financing round as lead investor, aiming to attract co-investors aligned with EeroQ’s U.S.-sovereign quantum roadmap.
2. Technology Cooperation Progress
The companies’ technology cooperation project has advanced to a proof of concept integrating SEALSQ’s secure semiconductor hardware, post-quantum cryptography, and PKI services with EeroQ’s helium-based quantum processor. This integrated Quantum Security Vertical Stack, to be showcased at SEALSQ’s Quantum Center of Excellence, leverages EeroQ’s one-million-qubit control architecture with fewer than 50 physical control lines.
3. Quantum Highway Strategy Alignment
The expanded funding supports scaling of EeroQ’s CMOS-compatible helium-based processors and expansion of its Chicago R&D footprint. This move reinforces SEALSQ’s Quantum Made in USA strategy and its broader Quantum Highway vision, creating a sovereign ecosystem for secure classical, post-quantum, and quantum processing in defense and critical infrastructure applications.
