SEALSQ Corp made a strategic investment in EeroQ, a U.S.-based quantum chip design company, as part of its “Quantum Made in USA” program to reinforce U.S. and European leadership in quantum-resistant technologies and future quantum computing platforms.

Earlier this year, SEALSQ launched SEALQUANTUM.com to invest up to $35 million in startups; the company finalized two transactions before this deal, including a partnership with ColibriTD and the acquisition of IC’ALPS. SEALSQ focused on developing and selling semiconductors, Public Key Infrastructure (PKI), and post-quantum hardware and software products and described plans to build an integrated post-quantum and quantum-era semiconductor ecosystem combining post-quantum cryptographic chips, quantum-resistant secure microcontrollers, advanced personalization centers in the USA and UAE, and future quantum accelerator chips developed in strategic partnership.

Founded in 2017, EeroQ aimed to construct a large-scale quantum computer using single electrons trapped on superfluid helium. Its design emphasized an ultra-compact form factor, CMOS-compatible fabrication, and single-electron qubits that provided metrics in coherence time, all-to-all connectivity, and qubit mobility that could enable novel architectures.

The investment was the first SEALSQ made in the USA under its stated strategy; EeroQ appointed Steve Lyon as chief technology officer and completed a 9,600 sq ft Research and Development (R&D) facility in Chicago. The companies described plans to combine EeroQ’s U.S.-based design and fabrication roadmap with SEALSQ’s secure semiconductor personalization and Outsourced Semiconductor Assembly and Test (OSAT) capabilities to support U.S.-sovereign and Europe-sovereign quantum technologies.

Carlos Moreira said, “Our strategic investment in EeroQ is a key step in SEALSQ’s ‘Quantum Made in USA’ industrial strategy. EeroQ’s helium-based quantum architecture is one of the most promising scalable designs we have seen. By aligning their breakthrough chip technology with SEALSQ’s secure semiconductor expertise, we are helping accelerate the development of quantum systems that are sovereign, secure, and industrially viable.”

The release contained forward-looking statements regarding SEALSQ's business strategy, financial performance, and expected developments and said those statements were subject to risks and uncertainties described in SEALSQ's filings with the SEC.
