Coherence Quantum raises €2.78M for quantum scaling technology

Coherence Quantum, a Finnish quantum hardware startup originating from Aalto University’s Quantum Computing and Devices research group, has raised €2.78 million in a seed funding round. The investment was led by Lifeline Ventures, with participation from technology entrepreneur Mårten Mickos.

The company is developing an integrated cryogenic signaling and control platform to address the infrastructure challenges of scaling quantum processors. As the number of qubits increases, traditional methods face limitations due to excessive wiring, complex signal conditioning, and restricted space and cooling capacity within dilution refrigerators.

CEO and co-founder Aashish Sah stated that quantum computers cannot scale simply by adding qubits; the surrounding infrastructure must evolve accordingly. Coherence Quantum aims to provide an architecture that supports larger systems without a proportional increase in wiring, cooling requirements, or complexity. The company is currently establishing research, testing, and manufacturing resources in Otaniemi, Espoo.
