Coherence Quantum Raises €2.78 Million in Seed Round

Coherence Quantum Raises €2.78 Million to Tackle Quantum‑Computer Scaling

Coherence Quantum, an Aalto University spin‑out based in Espoo, Finland, announced a €2.78 million seed round led by Lifeline Ventures with participation from technology entrepreneur Mårten Mickos. The funding will be used to establish a dedicated laboratory, develop product prototypes, advance manufacturing processes, and expand the team.

Why Cryogenic Infrastructure Matters

Quantum computers promise breakthroughs in materials science, drug discovery, and complex system modelling, but realizing those promises requires far more qubits than today’s devices can host. Adding qubits creates a parallel scaling challenge: the control and read‑out wiring, signal‑conditioning hardware, and cooling capacity needed to keep the quantum processing unit (QPU) stable. Conventional approaches rely on a growing tangle of room‑temperature cables and bulky electronics, which strain the limited space and cooling power inside a cryostat.

Coherence Quantum’s strategy is to move key components of the control stack closer to the qubits, operating them at cryogenic temperatures. By developing cryogenic signal‑conditioning technologies, the company aims to protect qubits from thermal noise while reducing the number of physical connections required. The roadmap proceeds from low‑temperature conditioning to higher‑density signal interfaces and eventually to integrated cryogenic control that sits directly on or near the QPU.

The Team and Technical Foundations

The founding trio brings deep expertise across the quantum hardware stack:

• Aashish Sah (CEO & Co‑founder) – Leads the vision of a scalable cryogenic control architecture.
• Suman Kundu (CTO) – An experimental quantum physicist who helped build Aalto’s 20‑qubit Q20 processor.
• Erkki Soininen (CPO) – Former product leader at cryogenics specialist Bluefors.

Advisory support comes from Mikko Möttönen, a professor of quantum technology at Aalto University, ensuring the company’s work stays closely tied to cutting‑edge academic research. Over the past two years, the team has produced multiple generations of cryogenic prototypes, validated in dilution refrigerators with actual qubit systems.

Investor Perspective

Lifeline Ventures’ partner Petteri Koponen highlighted the market need: “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.”

Angel investor Mårten Mickos 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. This type of sophisticated technology is needed to turn quantum computing into practical and scalable systems.”

Outlook and Impact

With the seed capital, Coherence Quantum will:

1. Set up a dedicated R&D and test facility in Espoo, close to Aalto’s ecosystem.
2. Produce first‑generation product prototypes that integrate cryogenic signal conditioning.
3. Develop a manufacturing pipeline to scale production as demand from quantum‑computer builders grows.
4. Expand the team across engineering, physics, and product development.

The company’s longer‑term ambition is to define a standardised blueprint for the cryogenic signalling and control stack, positioning its technologies alongside complementary solutions across the quantum hardware landscape. If successful, this could reduce the physical and thermal overhead of large‑scale quantum processors, making it easier for manufacturers to increase qubit counts without proportionally increasing system complexity.

Practical Takeaway

Coherence Quantum’s seed round underscores a shifting focus in the quantum industry: beyond building more powerful qubits, the ecosystem is now investing in the infrastructure that makes those qubits usable at scale. Stakeholders—from hardware vendors to research labs—should watch how the company’s cryogenic control platform evolves, as it may become a critical building block for the next generation of quantum computers.
