Coherence Quantum, a spinout from Aalto University, has secured €2.78 million in seed funding led by Lifeline Ventures to address a critical bottleneck in quantum computing scalability. The Finnish company is developing an integrated cryogenic signalling and control platform designed to streamline the infrastructure surrounding solid-state quantum processors. “Quantum computers won’t scale by adding qubits alone. The infrastructure around them has to scale too,” said Aashish Sah, CEO and co-founder of Coherence Quantum, as the team focuses on higher-density interfaces and integrated cryogenic control.

€2.78M Seed Funding for Cryogenic Control Platform Development

The seed funding round of €2.78 million, led by Lifeline Ventures, will directly support the establishment of Coherence Quantum’s research and development facilities in Espoo, Finland, enabling the company to build initial product prototypes and refine its manufacturing processes. This investment signifies a move beyond processor development and towards the essential infrastructure needed for larger, more stable quantum systems. Coherence Quantum intends to use the funds to expand its team and continue research into cryogenic signalling and control platforms, technologies designed to address the increasing demands placed on cooling and wiring as qubit counts rise.

The company’s approach focuses initially on cryogenic signal conditioning, a critical step in protecting the sensitive qubit environment from external disturbances. The core of Coherence Quantum’s technology builds upon over two years of focused research originating from Aalto University’s Quantum Computing and Devices group, resulting in multiple generations of cryogenic prototypes.

These prototypes have undergone validation within dilution refrigerators using actual qubit systems, demonstrating the feasibility of their integrated control platform, the company says. Multiple generations of cryogenic prototypes designed, fabricated, and tested, including validation in dilution refrigerators using qubit systems.

“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 founding team’s combined expertise is central to this development, bringing together skills in quantum physics, cryogenics, RF and microwave engineering and product development. Suman Kundu, CTO and an experimental quantum physicist, played a major role in establishing Aalto University’s 20-qubit Q20 quantum computer, while Erkki Soininen, CPO, previously led product development at a cryogenics company. Mikko Möttönen, a professor of quantum technology at Aalto University, is a founding advisor, providing continued guidance and support.

Petteri Koponen, Founding Partner of Lifeline Ventures, emphasized the importance of this comprehensive approach, stating, “They have an exceptional technical team with a clear view of where the industry is heading and the ambition to build far more than a single component.” Mårten Mickos, a technology entrepreneur and investor in Coherence Quantum, highlighted the broader implications of this work, noting, “This type of sophisticated technology is needed to turn quantum computing into practical and scalable systems.” He further added, “Coherence Quantum is addressing a pressing need in quantum computing, supporting large numbers of qubits while managing the growing challenges of heat, noise and complexity.” The investment acknowledges a shift in the quantum computing landscape, moving from solely focusing on qubit development to tackling the infrastructural challenges that hinder scalability. “The quantum industry has proved that increasingly capable processors can be built.

The next challenge is building the infrastructure that allows them to scale. Coherence Quantum is going after a fundamental part of that problem,” Koponen explained, reinforcing the strategic importance of the company’s work.

The company’s location in Espoo, Finland, positions it within a growing quantum technology ecosystem, encouraging collaboration and innovation, according to Coherence Quantum. Coherence Quantum’s goal is to enable the construction of quantum computers that are not only more powerful but also more manageable and efficient.
