Coherence Quantum, a spinout from Aalto University in Espoo, Finland, has raised €2.78m (about $3.1m) in a seed round. It announced the round on 20 October 2026.
Lifeline Ventures, a Helsinki early-stage firm, led the round. Mårten Mickos, the Finnish technology executive and investor, also took part, the company said.

“Quantum computers won't scale by adding qubits alone. The infrastructure around them has to scale too.”Aashish Sah, CEO and Co-founder, Coherence Quantum
What Coherence Quantum does
Coherence Quantum is working on the hardware that surrounds a quantum processor rather than the processor itself. Superconducting quantum computers run inside dilution refrigerators at temperatures close to absolute zero, and wiring and control signals have to reach every qubit. As machines grow, that supporting infrastructure becomes a bottleneck.
Its first technology focuses on cryogenic signal conditioning, which protects the environment around the qubit from thermal noise. The company then plans higher-density signal interfaces that carry more signals through the cryostat, and later control functions placed inside it, closer to the quantum processing unit. The platform is aimed at superconducting and spin-qubit systems. In the long run the company wants to set a standard blueprint for the cryogenic signalling and control stack, combining its own technology with that of other companies in the field.
"Quantum computers won't scale by adding qubits alone. The infrastructure around them has to scale too," said Aashish Sah, the chief executive and co-founder.
Tech.eu reported that the company grew out of more than two years of research at Aalto and has tested several generations of prototypes in dilution refrigerators.
"We're starting with signal conditioning and building towards higher-density interfaces," Sah told Tech.eu. He said the goal is an architecture that lets builders make larger machines without wiring, cooling needs and complexity growing at the same rate. The company says it has filed four patent applications covering its core technology.
The team and investors
Sah founded the company with Suman Kundu, its chief technology officer, and Erkki Soininen, its chief product officer. Mikko Möttönen, an Aalto professor, is a founding adviser. Sah is a quantum physicist who specialises in superconducting qubits and their electromagnetic environment. Kundu holds a PhD in superconducting quantum circuits and played a key role in setting up Aalto's 20-qubit Q20 quantum computer. Soininen, who has a PhD in physics, previously held a product leadership role at the cryogenics company Bluefors. Möttönen leads the Quantum Computing and Devices group.
Petteri Koponen, founding partner of Lifeline Ventures, said the industry has shown that ever more capable processors can be built. "This type of sophisticated technology is needed to turn quantum computing into practical and scalable systems," said Mickos. The company's website describes Mickos as a former chief executive of MySQL, which Sun Microsystems bought for $1bn.
The company came out of the Quantum Computing and Devices group at Aalto University.
What the money is for
Coherence Quantum said it will use the money to set up a lab in Espoo, build its first product prototypes and a manufacturing process, continue research and development, and hire. Its website says it is hiring cryoelectronics engineers, fabrication specialists and ASIC designers, and that it plans to work with quantum-computer builders through product supply, pilot projects and custom development.
The company has not said when it expects to ship its first product or how many people it employs.
