Coherence Quantum
Cryogenic signalling and control technology for scaling solid-state quantum computers
About
Coherence Quantum is a Finnish deep-tech startup spun out of Aalto University's Quantum Computing and Devices research group, led by CEO and co-founder Aashish Sah. It develops an integrated cryogenic signalling and control platform that improves signal conditioning and connections between control electronics and quantum processing units, so that larger quantum computers can be built without wiring, cooling and complexity growing at the same rate. Its team spent more than two years building and testing multiple prototype generations in dilution refrigerators with qubit systems. In October 2026 it raised €2.78 million to set up a lab in Espoo, build its first product prototypes and manufacturing processes, and grow the team.
