SEALSQ and Quobly
In a transformative move for the global technology sector, SEALSQ Corp officially announced its entry into a non-binding Memorandum of Understanding (MoU) to acquire a majority stake in Quobly SAS, the French pioneer in quantum microelectronics,. The $200 million transaction, which intends to build the first “secure-by-design” quantum computing platform in history, is a major consolidation in the European quantum scene.

A Strategic Union for Technological Sovereignty
The two businesses’ growing strategic partnership, which began in late 2025, is what led to the proposed acquisition. The organizations plan to create a sovereign infrastructure for Europe and its allies by combining Quobly’s cutting-edge silicon-based quantum computers with SEALSQ’s proficiency in Post-Quantum Cryptography (PQC).
SEALSQ’s founder and CEO, Carlos Moreira, stressed that the action is a fundamental part of the business’s long-term Quantum agenda. Moreira asserts that security must be integrated at the hardware level from the beginning as quantum computing develops into an essential strategic infrastructure. Industrialized, reliable quantum systems are intended to be produced by combining SEALSQ’s post-quantum Root-of-Trust capabilities with Quobly’s CMOS-compatible technology.
The Silicon Advantage: Scalability and Manufacturing
Often referred to as the “Silicon Valley of Europe,” Quobly was founded in 2022 and has made a name for itself by emphasizing scalability. Quobly uses conventional semiconductor manufacturing techniques (CMOS), in contrast to alternative quantum modalities like trapped ions or superconducting loops, which encounter major challenges in mass production.
Because this method addresses the industrialization issues now affecting the sector, Quobly’s quantum chips may be produced in already-existing semiconductor foundries, which is a very desirable feature. With the use of the semiconductor industry’s current worldwide infrastructure, Quobly hopes to introduce quantum processors to the market at a scale and speed that were previously unthinkable.

Elite Leadership and Scientific Pedigree
Quobly’s strength is found in both its leadership and its hardware. CEO Maud Vinet, a former employee of the esteemed French research agency CEA-Leti, and Tristan Meunier, who trained under Nobel winner Serge Haroche, co-founded the business.
The partnership with SEALSQ, a world leader in post-quantum security, will greatly speed up the commercialization of their secure silicon-based processors, Vinet said. Through this collaboration, the realities of industrial manufacturing are brought closer to the realm of advanced theoretical physics.
Financial Strength and the “Quantum Fund”
This $200 million investment will be backed by SEALSQ‘s Quantum Fund. This fund was created expressly to support the development of large-scale quantum technologies in Europe so that the continent may continue to compete with China and the United States in terms of rapid technological developments.
SEALSQ is a financially strong company going into this deal. The company released early 2025 financial measures the transaction was announced. These metrics showed a strong balance sheet with more than $425 million in cash. The company’s substantial liquidity guarantees that it has the funds required to finance the acquisition of Quobly and carry on with its R&D projects.

Defending Against the “Quantum Apocalypse”
The potential threat posed by the development of quantum computers is the main factor driving this merger. These devices might theoretically threaten practically all current encryption systems, such as RSA and Elliptic Curve Cryptography (ECC), as their power increases.
Developing “Quantum Resistant” hardware and software to avert a potential “quantum apocalypse” of global data security has always been SEALSQ’s primary goal. SEALSQ is moving from a defensive to a proactive stance by acquiring Quobly, gaining ownership of the gear that will shape computing in the coming century.
The merged company intends to offer safe, quick processing for a number of crucial industries, such as:
- Defense and Intelligence: Providing fast, secure processing to ensure national security.
- Financial Services: Preventing fraud facilitated by quantum computing in international markets and financial data.
- Pharmaceuticals: Using quantum simulation to speed up the search for novel medications.
- Industrial Automation: Keeping vital infrastructure intact is achieved through industrial automation.

The Road to Completion
The MoU’s clear aim to merge, there are still a number of procedural obstacles to overcome. A non-binding agreement turning into a legally binding contract and thorough due diligence that includes technical, financial, and legal evaluations are two examples.
Additionally, both French and European industrial regulators will probably scrutinize the acquisition closely. Authorities will want to make sure that the merger promotes technical sovereignty inside the European Union because of the strategic significance of quantum technology to regional and national security.
In conclusion,
Many industry observers see the SEALSQ-Quobly merger as a model for the semiconductor industry’s future. By combining post-quantum cryptography’s strict security with the raw computing power of silicon-based qubits, SEALSQ is establishing itself as the key designer of the next phase of digital existence.
The industry will be closely monitoring if this $200 million investment will turn Grenoble’s silicon inventions into the global standard for the quantum era as the battle for “Quantum Supremacy” heats up.
