Isentroniq, a French quantum hardware startup, has announced a €7.5 million ($8.7 million USD) funding round to develop and industrialize its wiring technology. The round was led by Heartcore, with participation from OVNI Capital, Kima Ventures, iXcore, Better Angle, and Epsilon VC. The funding is also supported by Bpifrance and the French National Research Agency (ANR) under the France 2030 program.
The company’s technology is designed to solve what it calls the “wiring deadlock” in superconducting qubits, which is a bottleneck to scaling due to heat, cost, and space constraints inside cryostats. The new wiring technology is intended to enable 1,000x more qubits to be integrated into existing dilution refrigerators. Isentroniq adopts a fabless model, leveraging a network of specialized manufacturing partners for production.
The funding will be used to industrialize the wiring technology, establish an engineering team, and build key industrial partnerships. The company’s mission is to deliver an end-to-end, plug-and-play solution enabling quantum computer builders to realize scaled-up systems. Paul Magnard, co-founder and CEO of Isentroniq, noted that the company’s mission is to turn wiring into an accelerator for superconducting quantum computers.
