Coherence Quantum, a Finland-based quantum hardware startup, has raised €2.78 million in a seed funding round led by Lifeline Ventures, with participation from technology entrepreneur Mårten Mickos. The funding will support the development of cryogenic signalling and control technologies designed to address infrastructure challenges in scaling quantum computers.
Founded in 2026 by Aashish Sah, Suman Kundu and Erkki Soininen, Coherence Quantum is headquartered in Espoo and originated from Aalto University’s Quantum Computing and Devices research group. Sah serves as CEO, Kundu as CTO and Soininen as CPO. The company is also supported by founding advisor Mikko Möttönen, a professor of quantum technology at Aalto University.
Coherence Quantum is developing an integrated cryogenic signalling and control platform for solid-state quantum computers, including superconducting and spin-qubit systems. Its technology is designed to manage signals between room-temperature electronics and quantum processors operating at extremely low temperatures.
As quantum processors incorporate more qubits, their supporting infrastructure requires increasingly complex wiring, signal conditioning and cooling systems. Coherence Quantum is addressing these constraints through hardware intended to reduce unwanted thermal noise and improve signal management within cryostats.
The company’s initial focus is on cryogenic signal conditioning, followed by higher-density signal interfaces and more integrated control functionality positioned closer to quantum processors. Its development work has included multiple generations of cryogenic prototypes tested in dilution refrigerators using qubit systems.
Coherence Quantum plans to use the new funding to establish its laboratory in Espoo, develop its first product prototypes and manufacturing processes, continue research and development, and expand its team.
The company was incorporated in June 2026 following research and experimental development at Aalto University. Its founding team combines expertise in quantum physics, cryogenics, microwave engineering, electronics and hardware product development.
