Isentroniq designs plug-and-play wiring architecture for superconducting quantum computers, targeting the thermal and spatial bottlenecks that stall machines at roughly 100 qubits. By shrinking heat load and footprint inside dilution refrigerators, its technology aims to accommodate up to 1,000× more qubits in existing cryostats and ultimately bring the cost of a 1-million-qubit system down to about €50 million. The company follows a fabless model, outsourcing fabrication to specialized partners to accelerate time-to-market and minimize capital expenditure while ensuring industrial-grade quality. Co-founded by superconducting-qubits expert Paul Magnard and repeat founder Théodore Amar, Isentroniq is positioning itself as an essential hardware enabler for quantum players such as Google, IBM, and Alice & Bob that are racing toward 100,000-plus qubit roadmaps. The startup will use its recent financing to advance product development, expand its team, and forge partnerships with quantum system builders. No revenue or user figures were disclosed, but the firm’s long-term vision centers on becoming the standard wiring solution for large-scale superconducting quantum computers.
