C12 Quantum Computing: Leading the Charge in Carbon Nanotube-Based Quantum Technology
French quantum computing startup C12, an innovative spin-off from the Physics Laboratory of the École Normale Supérieure in Paris, has successfully raised €18 million ($19.341 million USD) in its latest funding round. This financial boost, spearheaded by Varsity Capital with significant contributions from EIC Fund and Verve Ventures, aims to accelerate the development of C12's pioneering carbon nanotube-based universal quantum computers. The funds will be directed towards intensive R&D, particularly focusing on achieving high-fidelity quantum operations between two distant spin qubits linked by a communication bus.
The Funding and Its Purpose
The newly secured €18 million will facilitate C12's ambitious research and development agenda. This involves creating a high-fidelity quantum operation between two distant spin qubits, interconnected by a communication bus. Such advancements are crucial for realising the full potential of quantum computing, particularly in achieving long-distance entanglement—a fundamental milestone that could revolutionise computational speed and efficiency.
C12's CTO, Matthieu Desjardins, emphasised the importance of this goal: “Our objective is to demonstrate long-distance entanglement between 2 qubits. This entanglement is at the heart of the quantum leap that will one day allow us to compute in a few seconds what today takes several years. This long-distance 2Q gate is therefore a major step forward in quantum technology.” Source Tech.eu
Selection for France’s Proqcima Program
C12's potential and progress have been recognised through its selection for France’s Proqcima program, launched in March 2024 by the Ministry of the Armed Forces and the French Secretary General for Investment. This program aims to produce two French-designed prototypes of universal quantum computers by 2032, further cementing France's position as a leader in the global quantum race.

The Vision and the Backers
Pierre Desjardins, CEO and co-founder of C12, expressed his enthusiasm about the support from high-profile investors and the strategic vision driving the company: “I am very happy to have prestigious investors on board to speed up our development. I am proud that C12 can count on an extraordinary team. Our ambition is the same as on day one: to become one of the quantum computing leaders of tomorrow.”
Didier Valet, Founding Partner at Varsity, highlighted the significance of this investment: “We are proud at Varsity to lead the new C12 round with a clear objective to build a large-scale, fault-tolerant quantum computer and to strengthen France’s position as a leading force in quantum space.”
Historical Context and Technological Foundations
Since raising $10 million in 2021, C12 has made significant strides, both theoretically and empirically, demonstrating that its architecture—based on single spins in a vacuum—minimises noise sources that affect qubit quality. In October 2023, C12 launched the Quantum Fab, a unique production line for quantum processors in central Paris. This facility, featuring a cleanroom for semiconductor chips, marks a pivotal step towards mass-producing quantum processors.
Nader Sabbaghian, Partner at 360 Capital, compared this to the early days of digital computing: “Much like silicon laid the foundation for modern digital computing in the 1950s, we believe carbon holds the key to unleashing the extraordinary potential of quantum computing. We are immensely proud of C12's pioneering achievements to date and are committed to supporting their efforts to turn quantum computing into a tangible reality.” Source Tech.eu
C12's Carbon Nanotubes
C12 is brewing up something quite extraordinary with their carbon nanotube quantum computers. Imagine the quantum leap—literally—from the noisy neighbours of today’s qubits to the serene, whisper-quiet precision of C12’s distant entangled spins. I With France’s Proqcima program backing them and a hefty €18 million in their coffers, C12 is not just pushing the envelope; they’re rewriting the letter. Investors are on board, the tech is sound, and the vision is clear.

Commercial Applications
The advancements C12 is making could pave the way for numerous commercial applications. Quantum computers capable of high-fidelity operations between distant qubits could revolutionise fields such as cryptography, materials science, pharmaceuticals, and artificial intelligence. Industries relying on complex simulations and large-scale computations will particularly benefit from the enhanced processing power and efficiency offered by C12’s technology.
Current Blockers and Limitations
Despite the promise, several challenges remain. Achieving and maintaining high-fidelity operations over long distances is technically demanding. Quantum systems are notoriously sensitive to environmental disturbances, which can introduce errors. The development of robust error-correction techniques and fault-tolerant systems is crucial for the practical realisation of large-scale quantum computers. Additionally, scaling up production while ensuring consistency and quality in qubit performance poses a significant challenge.
Innovations
C12’s innovative use of carbon nanotubes sets it apart in the quantum computing landscape. By leveraging the unique properties of carbon nanotubes, C12 aims to reduce noise and enhance qubit stability. This approach not only addresses some of the fundamental limitations of current quantum systems but also opens up new possibilities for scalable quantum computing architectures. The establishment of the Quantum Fab production line is a testament to C12’s commitment to innovation and scalability.
Possible Future Applications
Looking ahead, the successful development of C12’s technology could unlock a myriad of future applications. From advancing scientific research with more powerful simulations to enhancing cybersecurity through quantum encryption, the potential impact is vast. Quantum computers could also revolutionise artificial intelligence, enabling more sophisticated algorithms and faster processing of large datasets. In healthcare, quantum simulations could lead to the discovery of new drugs and materials, accelerating the pace of medical advancements.
Conclusion
C12 is at the forefront of quantum technology, making significant strides towards realising the potential of carbon nanotube-based quantum computers. With substantial funding, strategic support from high-profile investors, and a clear vision, C12 is poised to become a leader in the quantum computing industry.
