QMill is a Finnish quantum-algorithm and software company founded in2024 and based in Espoo. It develops software for quantum-powered information security and hybrid quantum-classical optimization in telecommunications, transport, energy, finance and defense. Its Quantum Advantage Services platform provides researcher and developer tools, including an AI-powered circuit-compression service that reduces gate counts and circuit depth while preserving a circuit’s function, with hosted and private deployment plus API and SDK access. The company is developing quantum key-establishment and verifiable-computation methods, has demonstrated mobile-network encryption with Telia, and is working with ESL Shipping on assigning cargo across vessel fleets. Its broader quantum-advantage performance estimates are based on mathematical analysis and simulations; they are research results rather than a claim that universal industrial quantum advantage has already been demonstrated.
