The portfolio combines investments across two quantum architectures with acquired chip-design and photonic technology capabilities.

Rhea-AI Summary

SEALSQ (Nasdaq: LAES) outlined its investment strategy through SEALQuantum to bring hardware-based security into the infrastructure supporting quantum computers. The company aims to integrate secure chips and post-quantum cryptography, designed to resist quantum-computing threats, while that infrastructure is being designed.

Investments in Quobly and EeroQ span silicon spin qubits and electrons held above liquid helium, respectively.

5 terms

post-quantum cryptography technical

"bringing secure chips, hardware roots of trust and post-quantum cryptography into quantum computing infrastructure"

Post-quantum cryptography is a set of new methods for scrambling data so it stays secure even if powerful quantum computers exist; think of replacing today’s locks with designs that a future high‑speed lockpicker cannot open. For investors, it matters because companies must upgrade systems, meet regulations, and protect customer and trade data—creating costs, competitive advantages, or legal and reputational risks depending on how quickly and effectively they adopt these new security standards.

qubits technical

"Quantum processors rely on classical electronics and software to control qubits"

Qubits are the basic units of information in quantum computing, similar to how traditional computers use bits. Unlike regular bits that are either 0 or 1, qubits can represent both at the same time, allowing quantum computers to process complex problems much faster. This potential for unprecedented speed and power could transform industries, making qubits a key focus for investors interested in cutting-edge technology.

pki technical

"Semiconductors, PKI (Public Key Infrastructure), and Provisioning Services"

PKI (Public Key Infrastructure) is a system that creates and manages digital “keys” and electronic certificates to prove identities and secure online communications, like a bank vault and ID card for data. For investors, PKI matters because it helps prevent fraud, ensures that financial documents and trading instructions are genuine, and reduces regulatory and operational risk tied to hacked accounts or tampered disclosures.

elliptic curve cryptography technical

"traditional cryptographic methods like RSA and Elliptic Curve Cryptography (ECC)"

Elliptic curve cryptography is a method of creating secure digital keys and signatures using specific mathematical curves, offering strong protection with much smaller keys than older systems. For investors, it matters because it underpins security for online banking, trading platforms, digital assets and blockchain systems—affecting custody, transaction safety and regulatory compliance much like sturdy locks protect a warehouse full of valuables.

root of trust technical

"embedding a hardware Root of Trust that enables trusted hardware"

A root of trust is a small, tamper-resistant component inside a device or system that serves as the secure anchor for identity and data protection—think of it as a locked safe that holds the master keys and proof that the system is genuine. It matters to investors because a strong root of trust reduces the risk of hacks, supports regulatory compliance and customer confidence, and therefore can protect a product’s value and a company’s reputation.

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.
