5 terms

post-quantum cryptography technical

"By embedding Post-Quantum Cryptography into our semiconductor solutions"

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.

pki technical

"Our technology seamlessly integrates Semiconductors, PKI (Public Key Infrastructure)"

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.

fd-soi technical

"a proven 300 mm FD-SOI manufacturing platform"

FD-SOI (Fully Depleted Silicon On Insulator) is a semiconductor manufacturing technique that builds transistor switches on a very thin layer of silicon separated from the bulk wafer by an insulating layer, improving control over electricity flow. For investors, it matters because FD-SOI can deliver faster chips, lower power use and potentially lower production costs—like using a more efficient engine design—affecting a maker’s performance, market competitiveness and profit margins.

silicon spin qubits technical

"combining silicon spin qubits with advanced semiconductor manufacturing"

Silicon spin qubits are tiny quantum information units that use the orientation of an electron’s or nucleus’s magnetic moment inside silicon to represent 0 and 1, like a microscopic compass needle pointing one way or the other. They matter to investors because they promise a path to scalable, more easily manufactured quantum computers using existing chip-making techniques, which could reshape computing power, software markets and industries that rely on secure encryption.

metrology technical

"strengthen the advanced characterization, metrology and automated testing capabilities"

Metrology is the science and practice of making measurements accurate, consistent and traceable so numbers about size, weight, temperature or other properties mean the same thing everywhere. For investors it matters because reliable measurement underpins product quality, regulatory compliance and manufacturing efficiency—like using a well-calibrated ruler so every part fits—reducing recalls, legal risk and wasted costs that can affect a company’s earnings and reputation.

Geneva, Switzerland, Sept. 08, 2026 (GLOBE NEWSWIRE) --

Quobly’s new collaborations with TNO and Orange Quantum Systems support the transition of silicon-based quantum processors from laboratory research to industrial-scale deployment

SEALSQ Corp (NASDAQ: LAES) (“SEALSQ” or the “Company”), a global leader in post-quantum semiconductor, PKI and hardware security technologies, today highlighted the continued progress of its SEALQuantum strategy through Quobly, a French quantum computing company developing industrially scalable silicon-based quantum processors. SEALQuantum is a strategic quantum initiative through which the Company allocates its own capital across quantum and post-quantum technologies with the aim to develop a Sovereign Quantum Vertical Stack,

Through SEALQuantum, SEALSQ supports companies developing critical technologies for the next generation of sovereign digital infrastructure. These strategic, collaborative investments focus on quantum computing, post-quantum cybersecurity, trusted semiconductors, photonics and secure communications.

Quobly represents one of the flagship companies within this strategy. As a lead investor in Quobly’s €115 million Series A financing, SEALSQ made a significant commitment to support the research, development and industrialization of silicon-based quantum computing in Europe.

That investment has now grown into a strategic technology partnership. Earlier this year, SEALSQ and Quobly entered into a $5 million commercial agreement to integrate SEALSQ’s post-quantum security technologies into next-generation quantum computing platforms.

Furthermore, Quobly recently announced new collaborations with TNO and Orange Quantum Systems designed to strengthen the advanced characterization, metrology and automated testing capabilities required to accelerate the transition of scalable quantum processors from the laboratory to industrial deployment.

These developments provide concrete evidence of Quobly’s continued execution of its technology and industrialization roadmap, strengthening the capabilities required to manufacture, test and qualify silicon spin qubit devices at scale. They also reinforce the strategic objectives of SEALQuantum.

Carlos Moreira, Founder and CEO of SEALSQ commented, “Every commitment we make via SEALQuantum is designed with a focus on strategic collaborations with SEALSQ that accelerate research, development and ultimately comemrcialization, and Quobly demonstrates how that model can work. Quobly is a strong example of this approach. Our investment supports the development of silicon-based quantum computing, while our commercial agreement brings SEALSQ’s post-quantum security technology directly into the emerging quantum computing ecosystem. At the same time, we are working to convert strategic investments into contracted revenue and build a durable position in a quantum market that is moving from research into industrial deployment.”

Maud Vinet, Chief Executive Officer and Co-founder of Quobly added, “Building quantum computers at industrial scale requires more than developing high-performance qubits. It requires the engineering capabilities to manufacture, test and qualify them at scale. Our collaborations with TNO and Orange Quantum Systems strengthen two important parts of that industrialization effort. SEALSQ’s support, as both an investor and technology partner, complements this approach by bringing post-quantum security capabilities into the quantum computing platforms we are building.”
SEALSQ believes that scalable quantum computing systems will require security architectures capable of protecting processors, control systems, communications and digital identities against both classical and quantum-enabled cyber threats.

By combining Quobly’s silicon-based quantum processing capabilities with SEALSQ’s expertise in post-quantum semiconductors, secure elements and trusted digital identities, the companies are working toward a secure and sovereign technology foundation for the quantum era.

SEALSQ is proud to support Quobly as both a strategic R&D investor and technology partner as the company helps shape the future of secure, scalable and industrially deployable quantum computing in Europe.
