Qblox — Control Systems · fobi

Qblox

Qblox manufactures control electronics for quantum computing, offering modular hardware for qubit control and readout. Qblox raised $26M in Series A funding in June 2024 and is a spinout from QuTech at TU Delft. The company's products are used by IQM, Orange Quantum Systems, and academic labs.

The company's instruments are used by over 60 quantum labs globally, competing with Quantum Machines in the control electronics market.

Bull case

Qblox has already secured a strong beachhead in the control electronics market, with more than 60 quantum labs using its instruments. That installed base creates a switching-cost moat: researchers build their experimental workflows around Qblox's modular hardware and software stack, making it painful to rip and replace. The company's customer list includes IQM, one of Europe's leading quantum computer builders, and Orange Quantum Systems, signaling that production-grade quantum operators trust the hardware, not just academic tinkerers. Being a spinout from QuTech at TU Delft gives Qblox deep technical pedigree in a field where domain expertise matters enormously. As quantum processors scale beyond dozens of qubits, the control layer becomes a critical bottleneck — Qblox's modular architecture positions it to grow alongside customer systems without forcing a forklift upgrade. The €4.5M seed round, while modest, suggests capital-efficient operations and a focused product strategy that could allow the company to outrun its burn rate. If demand for quantum control systems compounds as the sector matures, Qblox's early lead in European labs could translate into a lasting commercial position.

Bear case

Qblox faces a Goliath in Quantum Machines, which has raised orders of magnitude more capital and already supplies control systems to major cloud platforms and national labs. Without disclosed recent funding, Qblox may be running on fumes while its well-capitalized rival extends the feature set with pulse optimization, AI-driven calibration, and tighter cloud integration. The company's customer base tilts heavily toward academic labs and a handful of European quantum startups — a narrow commercial moat. IQM could easily switch vendors as its supply chain matures, especially if Quantum Machines offers superior throughput or tighter latency guarantees at scale. The control electronics market is trending toward standardization and integration, which could commoditize modular hardware over time. Qblox's €4.5M raise is negligible compared to what will be required to compete for the big hyperscaler and HPC center contracts that will define the next growth wave. Without a clear path to Series A or a breakout commercial win, Qblox risks being outspent, out-featured, and squeezed into the academic long tail.
