Isentroniq Raises €7.5M To Overcome Wiring Challenges And Scale Quantum Computing

Quantum computing could transform industries such as medicine, energy, and logistics, but creating large-scale systems is very difficult. Millions of qubits are needed to manage errors, yet superconducting qubits are limited by cryogenic wiring. Systems over ~100 qubits face heat and space challenges, and scaling to 1 million qubits with current technology would require enormous facilities and tens of billions of euros.

Isentroniq addresses heat, cost, and space bottlenecks, aiming to enable up to 1,000× more qubits in existing dilution refrigerators. Its long-term goal is to reduce the cost of a 1 million-qubit system to ~€50 million. Operating a fabless model, Isentroniq designs its architecture and outsources fabrication to specialized partners, accelerating time-to-market, limiting capex, and ensuring industrial-grade quality.

Today, wiring is the #1 bottleneck to scale superconducting quantum computers. Our mission is to turn it into an accelerator, said Paul Magnard, co-founder and CEO.

Isentroniq was co-founded by Magnard, a superconducting qubits expert with a PhD from ETH Zurich and former lead architect at Alice & Bob, and Théodore Amar, a second-time founder with experience at Bain & Company and Hilti.

The announcement comes as major players including Google, IBM, Amazon, IQM, Alice & Bob, and Rigetti advance toward 100,000 to 1 million qubits.

The new funding will support development of Isentroniq’s wiring technology, expansion of the team, and building partnerships to deliver a plug-and-play solution for scalable quantum systems.
