SEALSQ Corp, Quobly to build scalable Post-quantum computing

Together, Quobly and SEALSQ will natively integrate post-quantum security into scalable quantum systems.

SEALSQ Corp and Quobly

A partnership to investigate the vital intersection of scalable quantum systems and secure semiconductor architectures has been announced by Quobly, a leader in silicon-based quantum microelectronics, and SEALSQ Corp, a global supplier of post-quantum semiconductor technologies and hardware-anchored security solutions. The collaboration seeks to develop scalable and safe quantum technologies for upcoming large-scale quantum computing.

Collaboration between large-scale quantum computing and secure hardware

Quobly’s highly scalable silicon-based quantum computing platform and SEALSQ’s well-established proficiency in post-quantum security technologies and hardware-anchored security solutions are connected by this strategic partnership. The main goal is to specify native architectures for quantum-secure systems. In order to determine how enhanced security hardware and quantum processing architectures can co-evolve as quantum computing moves closer to commercial implementation, the businesses intend to collaborate.

The partners aim to define how quantum-resistant security can be natively embedded into tomorrow’s large-scale quantum systems from the very beginning of design by fusing Quobly’s unique CMOS-compatible silicon spin qubit platform with SEALSQ’s Post-quantum cryptography and field-proven Root-of-Trust technologies. They aspire to be the first to investigate post-quantum cryptography and hardware Root-of-Trust built into large-scale, fault-tolerant quantum systems.

Strategic Market Focus and Accelerated Growth

The collaboration is expected to place both businesses at the center of the safe quantum future and yield definite strategic advantages.

SEALSQ benefits from early access to one of the world’s most sophisticated and scalable silicon qubit technologies through the partnership. SEALSQ can now accurately customize its Root-of-Trust solutions, TPMs (Trusted Platform Modules), and post-quantum secure parts to satisfy the demanding specifications of fault-tolerant quantum computers in the future this access.

In high-stakes marketplaces, the partnership expedites significance. Quantum systems that are both strong and provably secure are becoming more and more demanded by prominent organizations, including intelligence communities, defense agencies, financial institutions, and pharmaceutical leaders. Because of this partnership, SEALSQ is positioned as the preferred security layer for these vital applications. By bolstering its growth in the security sector, Quobly will gain an advantage.

Additionally, by accelerating growth in the extremely critical U.S. market, the partnership supports Quobly’s and SEALSQ’s expansion. Post-quantum security, high-performance computing, and trusted hardware are becoming more and more important in the US. In industries where scalable and secure computing architectures are crucial, such as critical infrastructure, defense, and security, the partnership strengthens Quobly’s position.

Combined Strengths Across Quantum and Security Technologies

Each partner’s unique offers play a major role in the convergence:

Quobly’s Scalable Quantum Platform:

Quobly creates completely silicon-based quantum processors that work with conventional industrial CMOS production. Their method makes use of the semiconductor ecosystem’s current maturity to create millions of high-fidelity silicon spin qubits on conventional wafers. With this method, a scalable route to fault-tolerant, industrial quantum computing is established.

Important technological components that Quobly has created include:

  • CMOS-compatible spin qubits made of silicon.
  • Cryogenic electronics for control.
  • Qubit arrays with high fidelity that are especially made for fault-tolerant systems.
  • Systems with several qubits require scalable interconnects.

The foundation of Quobly, which was established in 2022 in Grenoble, France, is more than 15 years of joint research between CNRS and CEA-Leti. To hasten the industrialization of its silicon quantum chips, the company has a strategic alliance with STMicroelectronics.

SEALSQ’s Post-Quantum Security Layer:

SEALSQ is a world leader in post-quantum semiconductors, TPM chips, secure elements, and hardware-anchored Root-of-Trust solutions. Critical infrastructure, digital identification solutions, industrial systems, Internet of Things networks, and satellites around the world are all protected by its quantum-resistant security modules and semiconductor platforms.

Among the innovations of SEALSQ are:

  • Dilithium, CRYSTALS-Kyber, and hybrid schemes are examples of PQC algorithms that are tailored for embedded systems.
  • TPMs and quantum-safe secure elements.
  • Secure semiconductor personalization is made possible by cutting-edge OSAT facilities.
  • Hardware authentication and trusted execution are provided by root-of-trust frameworks.
  • Quantum-safe communication stacks for IoT, satellite, automobile, and critical systems applications.

As quantum computers develop, established cryptographic techniques like Elliptic Curve Cryptography (ECC) and RSA become more and more susceptible. To provide strong, future-proof protection for critical data, SEALSQ is leading the way in Post-Quantum Semiconductors.

Executive Commentary on the Future of Secure Computing

The strategic need of the partnership was affirmed by executives from both companies.

Building scalable quantum processors using industrial-grade semiconductor technology is Quobly’s primary priority, according to Maud Vinet, co-founder and CEO. The next logical step as quantum computing advances towards practical uses, she continued, is to investigate complementarities with post-quantum security. Vinet stated that integrating the teams’ knowledge will improve their positions in the security and defense industries and hasten the US market’s growth.

Future digital infrastructure protection depends on the confluence of secure semiconductor technology with quantum computing, according to Carlos Moreira, the founder and CEO of SEALSQ. According to Moreira, by combining SEALSQ’s post-quantum Root-of-Trust technologies with Quobly’s scalable quantum platform, they are creating the framework for independent quantum systems that Europe can completely industrialize, trust, and govern. He came to the conclusion that this collaboration enhances the groundwork for next-generation secure computing systems and speeds up Europe’s journey towards quantum independence.
