FirstQFM

FirstQFM AB is a Stockholm-based quantum technology company that develops proprietary AI foundation models designed to enhance the performance, scalability, and reliability of quantum computers across the quantum computing stack. In October 2025, FirstQFM raised €1.2 million in pre-seed funding led by BSV Ventures with participation from Almi Invest, Further than Capital, and Luminar Ventures to accelerate development of patent-pending machine learning foundation models that improve NISQ-era quantum machines and support progress toward fault-tolerant quantum computing. FirstQFM’s core offering consists of machine learning foundation models that sit beneath the quantum software stack, analyzing and optimizing the behavior of qubits before and during computation by feeding real-time telemetry from superconducting or photonic hardware into its models to predict calibration drifts, detect anomalous error patterns, and suggest corrective pulse sequences. The company partners with quantum hardware developers to enhance device calibration and error correction, working with a global network of partners and experts to accelerate the transition of quantum computing from experimental stages to real-world industrial use.
