IQM Quantum Computers is a Finnish maker of superconducting quantum computers and the first European quantum company to trade on a major US exchange, completing a SPAC merger and beginning to trade on Nasdaq as IQMX around July 2026, dual-listed on Nasdaq Helsinki. It has sold 21 quantum systems to 13 customers. Its choice of a US listing over waiting for Europe's €5 billion Scaleup Europe Fund became a signature example of European deep-tech listing abroad. In October 2026 it prepared a GHZ state across all 54 qubits of its Emerald processor, with a fidelity of 0.516 using readout error mitigation.
