SEALSQ and Quobly Announce Potential $200 Million Acquisition to Build Secure Silicon Quantum Systems
The Quantum Frontier: SEALSQ and Quobly's $200 Million Acquisition to Secure Silicon Quantum Systems
In a groundbreaking move, SEALSQ Corp (NASDAQ: LAES) has entered into a non-binding Memorandum of Understanding (MOU) for the strategic investment and potential majority acquisition of Quobly SAS, a French pioneer in silicon-based quantum computing. This multi-stage transaction, anchored by SEALSQ's recently expanded $100 million Quantum Fund, could result in a total investment of approximately $200 million. This acquisition follows a strategic collaboration established in November 2025 and aims to create a vertically integrated platform that combines Quobly's CMOS-compatible hardware with SEALSQ's post-quantum "Root-of-Trust" security capabilities.
The Power of Silicon Quantum Computing
Quobly, a 2022 spin-off from CEA-Leti and CNRS based in Grenoble, specializes in developing quantum processors using standard 300 mm FD-SOI semiconductor manufacturing processes. This industrial approach allows Quobly to leverage the existing global microelectronics infrastructure to scale silicon spin qubits toward the millions required for fault-tolerant operation. The company is currently advancing its Q100T program, which targets the production of a 100-physical-qubit silicon chip by 2027. Quobly also maintains a strategic manufacturing partnership with STMicroelectronics, further reinforcing its "industrial-grade" roadmap.
The use of silicon-based quantum computing has several advantages over other approaches. Silicon is a well-established material in the semiconductor industry, and its use in quantum computing allows for the creation of highly scalable and fault-tolerant systems. Additionally, silicon quantum computing can be integrated with existing classical computing systems, making it easier to adopt and deploy.
The Importance of Secure Quantum Systems
Strategically, the acquisition is designed to establish a "secure-by-design" reference platform for quantum infrastructure. By embedding quantum-resistant security directly at the hardware level during the design phase, SEALSQ and Quobly intend to serve mission-critical sectors such as defense, intelligence, and financial services. According to SEALSQ CEO Carlos Moreira, the goal is to build sovereign, trusted quantum systems for Europe and its strategic partners, ensuring that future quantum infrastructures are resilient against the very threats that quantum computers themselves pose to traditional cryptography.
The need for secure quantum systems is becoming increasingly pressing. As quantum computing becomes more widespread, it will be used to break many of the encryption algorithms currently in use. This will create a significant security risk, as many of the systems currently in use will be vulnerable to attack. By developing secure quantum systems, SEALSQ and Quobly are helping to mitigate this risk and ensure that the benefits of quantum computing can be realized while minimizing the risks.
The Implications of the Acquisition
The acquisition of Quobly by SEALSQ has significant implications for the development of quantum computing. By combining Quobly's CMOS-compatible hardware with SEALSQ's post-quantum "Root-of-Trust" security capabilities, the company will be able to create highly secure and scalable quantum systems. This will enable the company to serve a wide range of customers, from defense and intelligence agencies to financial services and other mission-critical sectors.
The acquisition also has implications for the broader quantum computing industry. By establishing a "secure-by-design" reference platform for quantum infrastructure, SEALSQ and Quobly are helping to set a new standard for the development of quantum systems. This will help to ensure that the benefits of quantum computing can be realized while minimizing the risks, and will help to drive the adoption of quantum computing in a wide range of industries.
