Quantum Machines buys PCB Engineering in second European deal in six weeks

Quantum Machines has acquired Hungarian PCB Engineering and opened a Budapest R&D hub, expanding its control-systems business as the quantum industry moves closer to practical advantage. The deal adds to the company’s global footprint and comes after a $170 million Series C last year. Why it matters: - Quantum Machines is building more hardware and engineering capacity around the control systems that sit between quantum processing units and usable quantum computers. - The acquisition adds another European base as quantum developers race to make fault-tolerant systems practical. - The deal strengthens Quantum Machines’ position across multiple quantum modalities, from neutral atoms to superconducting qubits and trapped ions. What happened: - Quantum Machines acquired Hungarian company PCB Engineering. - The transaction is Quantum Machines’ second European acquisition in six weeks. - The company established a new Budapest R&D hub. - Quantum Machines said the move will help accelerate its roadmap as quantum advantage appears closer. - The company operates with employees in 22 countries and major offices across the U.S., Denmark, Germany, Israel, Japan, Singapore, the Netherlands and Hungary. - Quantum Machines said its control systems are used by more than half of the world’s quantum computing companies. The details: - Quantum Machines said it is deepening its hybrid quantum-classical control architecture, which is used to turn QPUs into useful quantum computers. - The company’s work spans neutral atoms, superconducting qubits, trapped ions and spin qubits. - Quantum Machines also serves hyper-scalers, data centers, national labs, university labs and startups. - Itamar Sivan, co-founder and CEO of Quantum Machines, said quantum computing is nearing a turning point and fault-tolerant quantum computers will not be far behind. - Sivan said Quantum Machines has built the industry’s biggest quantum control team and is making the biggest investments in quantum control, by far. - Janos Lazanyi, founder and CEO of PCB Engineering, said his team has spent two decades designing high-speed, high-density systems and complex hardware architecture for high-performance computing. - Lazanyi said joining Quantum Machines will let PCB Engineering’s engineers apply that experience to hardware for quantum computing. - Lazanyi said Hungary’s tech and talent will play a central role in shaping the future of quantum computing through the combined effort. - Shaul Galila, COO of Quantum Machines, said control hardware must be the strongest link in a quantum computer and has to perform precisely and reliably every time. - Galila said PCB Engineering’s engineers bring a track record of turning demanding designs into hardware that works in the real world. Between the lines: - Quantum Machines is moving beyond software-style orchestration and into geographic and engineering scale. - The Budapest hub suggests the company wants deeper access to European talent as competition intensifies in the hardware layer around quantum systems. - The company is framing control infrastructure as a strategic bottleneck, not just a support function, as the sector moves toward scale. - Quantum Machines closed a $170 million Series C in 2025, bringing total funding to $280 million. - The company pointed to rising global quantum investment, with leading developers committing tens of billions to fault-tolerant systems this decade. What’s next: - Quantum Machines is expected to use the new Budapest hub to speed up product development and expand its control-platform roadmap. - The company’s next phase will likely focus on scaling the hardware and software stack that supports larger quantum systems. - As investment in quantum computing grows, the competitive focus is shifting toward the infrastructure built around the qubit. The bottom line: - Quantum Machines is using acquisitions to build out the infrastructure layer that could determine which quantum systems scale first. More information
