SEALSQ Increases Strategic Investment in EeroQ to Advance “Quantum Made in USA” Strategy SEALSQ Corp (NASDAQ: LAES) has finalized a second strategic investment in EeroQ, a U.S.-based quantum hardware company developing an architecture based on electrons on superfluid helium (eHe). This follow-on investment, executed through the SEALQUANTUM.com platform, builds upon SEALSQ’s initial entry into EeroQ in December 2025. The capital injection is part of a broader “Quantum Made in USA” strategy intended to establish a sovereign, vertical security stack that integrates post-quantum cryptography (PQC) with scalable quantum processing units (QPUs). The eHe architecture utilizes electron spins trapped on a superfluid helium surface, a method that offers long coherence times and CMOS-compatible fabrication. EeroQ recently validated a control architecture—centered on its Wonder Lake chip—capable of managing up to one million qubits using fewer than 50 physical control lines. This addresses the “wire problem” inherent in superconducting and trapped-ion systems, where the thermal and physical overhead of thousands of individual coaxial cables often prevents large-scale integration. By reducing system complexity and power dissipation, EeroQ’s platform allows for ultra-compact quantum processors potentially as small as a thumbnail. As part of this expanded partnership, SEALSQ and EeroQ will develop a Proof of Concept (PoC) at the SEALSQ Quantum Center of Excellence in Geneva. This platform will demonstrate a complete “Quantum Security Vertical Stack,” linking SEALSQ’s secure semiconductor hardware and PKI services with EeroQ’s quantum processing roadmap. This “Quantum Highway” initiative is designed to create a trusted industrial pipeline where secure classical and quantum processing coexist, providing a reference architecture for national security and critical infrastructure providers evaluating quantum-resistant systems.
