A Finnish quantum hardware company has secured €2.78 million in seed funding to advance its cryogenic signalling and control platform for quantum computers. Lifeline Ventures led the round, joined by technology entrepreneur Mårten Mickos.
Coherence Quantum emerged from the Quantum Computing and Devices (QCD) research group at Aalto University and is building an integrated cryogenic signalling and control platform to tackle the infrastructure bottlenecks that emerge as quantum processors scale.
The fundamental problem is straightforward: as quantum computers gain more qubits, the control and readout systems become exponentially more demanding. Traditional approaches pile on extra wiring and signal-conditioning hardware inside cryogenic environments where space is scarce and cooling capacity is finite. Quantum processors themselves must stay isolated from thermal noise and other environmental interference that degrades their performance.
Coherence Quantum's approach focuses on improving signal conditioning and creating more efficient pathways between control systems and the quantum processing units themselves.
We're starting with signal conditioning and building towards higher-density interfaces and, ultimately, more integrated cryogenic control. Our aim is to give quantum-computer builders an architecture that can support larger systems without wiring, cooling requirements, and complexity growing at the same rate.

The company's technology rests on more than two years of development and testing conducted at Aalto University. The team has built and iterated through multiple prototype generations, running validation tests inside dilution refrigerators with actual qubit systems.
The fresh capital will fund several near-term priorities: setting up a laboratory facility in Espoo, building and testing the first commercial product prototypes, establishing manufacturing processes, continuing research efforts, and hiring additional staff.
Looking ahead, Coherence Quantum intends to help shape a standardised architecture for cryogenic signalling and control systems by combining its own innovations with complementary technologies from the broader quantum industry.
