Coherence Quantum raises €2.78M seed for cryogenic quantum control
Three Aalto physicists raised €2.78M from Lifeline Ventures to fix the part of quantum computing nobody photographs: the wiring and control electronics inside the cryostat.

Founded 2026 · Espoo, Finland
Coherence Quantum, a 2026 spinout of Aalto University based in Espoo, has raised a €2.78M seed round led by Lifeline Ventures, joined by technology entrepreneur Mårten Mickos, to build the cryogenic signalling and control systems that solid-state quantum computers need to scale.
Below, I lay out what the round funds, why the control layer is suddenly the interesting end of quantum, and what a Helsinki fund leading two deep-tech seeds in one week tells us about where Nordic capital is going.
A seed for the coldest part of the stack
The €2.78M seed, announced on 20 October 2026, is led by Lifeline Ventures, the Helsinki-based early-stage firm, with technology entrepreneur Mårten Mickos investing alongside. The money establishes the company’s laboratory in Espoo, funds its first product prototypes and the manufacturing process behind them, and grows the team while research continues.
“The quantum industry has proved that increasingly capable processors can be built,” said Petteri Koponen of Lifeline Ventures in the announcement. The harder question sits around those processors: the wiring, the shielding, the signal conditioning that keeps a qubit usable at all.
Three physicists out of Aalto’s cold lab
Coherence Quantum was founded in 2026 out of Aalto University’s Quantum Computing and Devices group, after more than two years of cryogenic signalling and control research and multiple generations of prototypes tested in dilution refrigerators on live qubit systems. CEO Aashish Sah is a quantum physicist specialised in superconducting qubits, CTO Suman Kundu helped build Aalto’s 20-qubit Q20 machine, and CPO Erkki Soininen held a product leadership role at cryogenics company Bluefors. Mikko Möttönen, professor of quantum technology at Aalto, advises.
The product is an integrated cryogenic signalling and control platform for solid-state quantum computers, superconducting and spin-qubit systems alike. The first products handle cryogenic signal conditioning, protecting the qubit environment from thermal noise; higher-density signal interfaces and control functionality inside the cryostat, closer to the quantum processing unit, come next.
“Quantum computers won’t scale by adding qubits alone,” said Sah in the announcement. Every additional qubit drags more wiring and signal-conditioning hardware into a space with almost no room and even less cooling capacity. Qubit counts make the headlines; wiring is what makes them true.
The $20bn market behind the cryostat door
The global quantum computing market stands at $3.52bn in 2025 and is forecast to reach $20.2bn by 2030, a 41.8% CAGR (MarketsandMarkets, September 2025). A growth rate like that moves the bottleneck down the stack: every new processor generation needs conditioning, interfaces and control electronics that today are largely hand-built, which is exactly the layer Coherence Quantum wants to standardise.
Our own records show the European end of that curve filling in. Qilimanjaro Quantum Tech closed a €19.6M Series A first close in Barcelona on 14 October (Sesamers fundraising data), a year after quantum hardware seeds like QFX’s €2.2M round. And the bigger European cheques are going to the same thesis one layer up: Salience Labs’ $125M Series B for photonic interconnect is also infrastructure for machines that compute differently.
Lifeline’s second deep-tech seed in six days
The good news is that this looks like a pattern, not an exception. Lifeline Ventures led Ambio’s €5.1M advanced-materials seed on 14 October (Sesamers fundraising data), which makes two deep-tech seed leads from one Helsinki fund in under a week. We are watching generalist Nordic capital walk into labs it would have called “too early” three years ago.
So why does a three-founder control-electronics company matter more than another qubit-count record? Because Finland already owns the cold end of this industry: Aalto’s quantum group, the dilution-refrigerator know-how Soininen carries over from Bluefors, IQM a few kilometres away in Espoo. We keep asking where Europe’s quantum advantage will come from, and in the Nordics part of it is already installed and running cold.
What to watch now: whether Coherence Quantum’s conditioning hardware turns up inside other European machines, and whether a standardised control architecture emerges from Espoo rather than from a US lab’s internal stack. Europe’s quantum bet is increasingly the enabling layer. Watch the cold boxes, not just the qubit counts.
