SEALSQ Deepens EeroQ Bet, Leads Round Backing 1 Million-Qubit Control Architecture

SEALSQ made another strategic investment in EeroQ and agreed to anchor the U.S. quantum chip designer’s next priced financing round, extending a partnership it had already funded in December 2025 and February 2026.
EeroQ’s helium-based, CMOS-compatible platform helped drive the decision, especially a control architecture the companies said can manage up to 1 million qubits with fewer than 50 physical control lines.
The expanded tie-up also broadens joint work on a quantum security stack that would combine SEALSQ’s secure semiconductors, post-quantum cryptography and PKI services with EeroQ’s processor technology.
SEALSQ said the investment supports its “Quantum Made in USA” and Quantum Highway strategies, aimed at building sovereign quantum infrastructure for defense, national security and critical systems.
