SEALSQ Outlines Its Investment Strategy in Quantum Computing and Security

Geneva, Switzerland, Nov. 10, 2026 (GLOBE NEWSWIRE) --

Through SEALQuantum, the Company aims to build hardware-based security into the systems that control, operate and connect quantum computers and create opportunities for long-term growth.

SEALSQ Corp (Nasdaq: LAES), ("SEALSQ" or "Company"), a developer of secure semiconductors and post-quantum cryptography solutions, today outlined the strategic and commercial rationale for its investments in quantum computing through SEALQuantum. The Company’s Root-to-Qubit strategy focuses on bringing secure chips, hardware roots of trust and post-quantum cryptography into quantum computing infrastructure while that infrastructure is being designed. The objective is to position SEALSQ as a supplier of security technologies for this emerging market while expanding applications for its existing semiconductor expertise.

Quantum processors rely on classical electronics and software to control qubits, authenticate operators, verify firmware updates and communicate with other systems. Those functions create points where hardware-based security can help verify a device’s identity, establish who is authorized to operate it and protect the data it exchanges.

“Quantum computers will depend on classical systems for many of their most critical functions,” said Carlos Moreira, Founder and CEO of SEALSQ. “Our investment strategy is designed to connect SEALSQ’s security expertise with the companies developing this infrastructure. By engaging early, we aim to identify opportunities to integrate our technologies into their designs and build relationships that can support future commercial adoption. We are pursuing that longer-term opportunity alongside applications for post-quantum security in systems customers use today.”

Building a Portfolio Across Quantum Computing and Security

SEALSQ’s investments and acquisitions bring together complementary capabilities across quantum processors, supporting electronics, connectivity and security applications in existing markets.

Together, they are intended to expand the potential applications of the Company’s core security technologies as quantum infrastructure develops.

Working across distinct quantum computing architectures

• In France, Quobly is developing silicon spin qubits using established semiconductor manufacturing techniques.
• In the United States, EeroQ is developing qubits based on electrons held above liquid helium. SEALSQ’s investments in both companies give it an opportunity to explore how hardware-based security can be applied across two distinct architectures.
• Its acquisition of IC’ALPS, a French custom chip design specialist, adds expertise in designing the classical electronics that support quantum processors, including circuits for cryogenic environments.
  
  

Connecting quantum systems and testing practical applications

• Swiss-based Miraex, acquired by SEALSQ, is developing photonic technology designed to convert microwave signals into optical signals, a step toward linking quantum processors over optical networks.
• WISeSat.Space provides a platform for deploying and testing post-quantum security in low Earth orbit. Separately, SEALSQ is working with ColibriTD and Xdigit to explore whether quantum algorithms can help model voltage drop in advanced chip designs.

Applying the same security principles to infrastructure in use today

• In Spain, Quantix Edge Security is developing local semiconductor testing and personalization capabilities, including secure key provisioning.
• SEALSQ’s majority investment in Wecan Group provides a route to bring post-quantum protection into digital identity, secure data exchange and compliance workflows used by financial institutions.

Together, these initiatives reflect the scope of SEALSQ’s Root-to-Qubit strategy, from the first cryptographic key provisioned on a chip to the networks that could connect quantum processors. Scaling quantum computing is not only about increasing the number of qubits; it is also about ensuring those qubits can operate within a trusted ecosystem. SEALSQ addresses both challenges by supporting qubit scalability while embedding a hardware Root of Trust that enables trusted hardware, authenticated operators, and verifiable data integrity across the quantum infrastructure.
