Hybrid quantum-classical control solutions provider Quantum Machines (QM) has announced the acquisition of Hungarian hardware design firm PCB Design Ltd.. Marking QM’s second European corporate consolidation in a six-week window, the transaction establishes a dedicated research and development hub in Budapest to accelerate the scaling of the company’s real-time hardware orchestration portfolio. By absorbing PCB Engineering’s specialized workforce of 40 developers, the move deepens QM’s global infrastructure footprint, positioning its engineering assets across 22 countries to support high-performance control demands closer to near-term fault-tolerant hardware limits.
The expansion follows QM’s recent acquisition of QHarbor, a software data-management spin-out from the Delft University of Technology (TU Delft) in the Netherlands. While the Delft acquisition focused on closing data-layer visualization and storage bottlenecks within complex physics experiments, the Budapest team injects twenty years of classical high-speed, high-density hardware architecture expertise directly into QM’s physical control stack. This discipline is vital for engineering low-temperature, ultra-low-noise interconnect topologies capable of transitioning raw quantum processing units (QPUs) into stable, synchronized computers.
QM’s flagship Orchestration Platform is currently deployed by more than half of the world’s quantum computing developers, commanding a diverse commercial footprint that spans neutral-atom, superconducting, trapped-ion, and spin-based qubit modalities. Operating across data centers, cloud hyperscalers, national security complexes, and academic research labs, the firm leverages a $170 million Series C funding round finalized in 2025 to fund massive system-level investments. The integration of PCB Engineering’s high-speed design background directly supports QM’s mission to optimize the classical electronics surrounding the core QPU, ensuring that control loops maintain perfect timing and sub-nanosecond precision as industrial developers transition from handfuls of physical qubits to thousands of logical qubits this decade.
