Isentroniq Secures €7.5M to Revolutionize Quantum Wiring Solutions

French deeptech startup Isentroniq has successfully raised €7.5 million to address a critical challenge in the field of quantum computing: the wiring bottleneck. This funding will allow the company to develop innovative wiring solutions that promise to enhance the scalability and efficiency of quantum systems, paving the way for broader applications in various industries, including medicine and energy.

Current quantum computers rely on qubits, which represent information in quantum states. To maintain stability, these qubits must be cooled to nearly absolute zero, necessitating thousands of ultra-thin wires that run through cryogenic chambers known as dilution refrigerators. Each wire introduces heat, occupies valuable space, and increases costs, creating significant limitations in existing systems. Presently, these systems can only manage a few hundred qubits before reaching their operational limits. To achieve practical, fault-tolerant quantum computing, systems capable of handling millions of qubits are essential, yet this requires substantial facilities and investments, potentially costing billions.

Isentroniq aims to tackle this wiring crisis by developing technology that allows integration of up to 1,000 times more qubits within existing cryostats. By reducing heat transfer, physical bulk, and cabling expenses, the startup’s innovation could lower the cost of a million-qubit machine from tens of billions to approximately €50 million, significantly advancing the feasibility of commercially viable quantum computing.

Funding and Strategic Growth Plans

The recent funding round was led by Heartcore and included participation from OVNI Capital, Kima Ventures, and others, with backing from Bpifrance and the French National Research Agency (ANR) under the France 2030 initiative. This capital will enable the Paris-based company to expand its engineering team, further develop its proprietary technology, and establish industrial partnerships to create a plug-and-play infrastructure for quantum computer manufacturers.

Isentroniq adopts a fabless production model, which means it designs the architecture while outsourcing manufacturing to specialized partners. This approach not only ensures high-quality production but also accelerates deployment without incurring heavy capital expenditures.

Founders with Vision and Expertise

The driving force behind Isentroniq includes co-founders Dr. Paul Magnard and Théo Amar. Dr. Magnard, who holds a PhD from ETH Zurich and previously served as lead architect at Alice & Bob, possesses extensive expertise in superconducting qubits, with numerous publications in prominent journals such as Nature. Théo Amar brings valuable experience from his time at Bain & Company and Hilti, focusing on market strategies and operational scalability.

Together, they aim to resolve one of quantum computing’s most persistent infrastructure challenges. As tech giants like Google, IBM, and Amazon push towards achieving million-qubit systems, Isentroniq’s innovations could serve as the foundational layer that makes these ambitious goals attainable.

Looking forward, Isentroniq plans to expand its workforce by 2026, seeking to recruit quantum, mechanical, and RF engineers, as well as software specialists. Dr. Magnard, co-founder and CEO, emphasized the urgency of addressing wiring challenges: “Today wiring is the #1 bottleneck to scale-up superconducting quantum computers. Our mission is to turn it into an accelerator. With this funding, we will industrialise a wiring technology capable of supporting million-qubit machines and make quantum computing truly useful for science, industry, and society.”
