QMill

QMill is a Finnish quantum computing company developing quantum-advantage algorithms and software designed to run on near-term quantum computers in the noisy intermediate-scale quantum (NISQ) era. Its first product, QMill Circuit Compression, is an AI-powered service that compresses, runs, and compares quantum circuits — enabling useful quantum computations sooner. QMill's algorithms have demonstrated a six-fold leap toward practical quantum advantage, requiring only 48 qubits, and its AI-powered compression method was trained using the LUMI supercomputer. The company aims to unlock real-world industrial applications of quantum computing ahead of full fault-tolerant hardware availability.
