Coherence Quantum, EUR 2.78M seed for cryogenic quantum control
Coherence Quantum says its team has spent more than two years on cryogenic signalling and control hardware, through several prototype generations tested in dilution refrigerators with qubit systems, and that four patent applications cover its core technologies. On 20 October 2026 the Finnish company announced a €2.78 million seed round led by Lifeline Ventures, with technology entrepreneur Mårten Mickos also taking part.
The research comes out of the Quantum Computing and Devices group at Aalto University. The problem it targets is infrastructure. As quantum computers gain qubits, they need more control and readout electronics, and the usual approach adds wiring and signal-conditioning hardware inside a cryostat with limited space and cooling capacity. CEO Aashish Sah: "We're starting with signal conditioning and building towards higher-density interfaces and, ultimately, more integrated cryogenic control."
The company's own site says it starts with cryogenic signal-conditioning technologies that protect the qubit environment. According to tech.eu, its longer-term aim is to contribute to a standardised architecture for cryogenic signalling and control, combining its own technology with other parts of the quantum ecosystem.
Who gave the money: Lifeline Ventures, which the company's site calls its lead investor and describes as a Helsinki-based early-stage venture capital firm, and Mårten Mickos. No public funder is named in what is published.
The limits: the patents are applications, not granted patents. No valuation, no split of the round between investors and no customers are published. The two-year and four-application figures are the company's own.
What the money pays for: according to tech.eu, a laboratory in Espoo, the first product prototypes and manufacturing processes, continued research and development, and a larger team.
