Netherlands Quantum Computing Companies 2026: Complete Vendor Guide

The leading netherlands quantum computing companies in 2026 form one of the most tightly clustered quantum ecosystems in the world, built around the QuTech research institute in Delft and funded by Quantum Delta NL, the national programme that secured EUR 615M from the Dutch National Growth Fund. The country now ranks second worldwide in quantum science behind only the United States, and private investment in its quantum sector has grown roughly sixteenfold since 2019, reaching about EUR 160M in 2025 across some 29 startups. Ten organisations define the Dutch sector in this guide: QuTech (Delft, the TU Delft and TNO research anchor), QuiX Quantum (Enschede, photonic processors), QuantWare (Delft, superconducting QPU foundry), Qblox (Delft, control electronics), Fermioniq (Amsterdam, emulation software), Single Quantum (Delft, photon detectors), QphoX (Delft, microwave-optical transduction), Delft Circuits (Delft, cryogenic cabling), Orange Quantum Systems (Delft, chip diagnostics), and Q*Bird (Delft, quantum key distribution). Each card below lists the company focus, location, and latest funding for quick reference. Why the Netherlands punches above its size in quantum The Netherlands is a small country by population, yet it operates one of the densest quantum-computing ecosystems on the planet, and the reason is concentration rather than scale. Almost the entire Dutch quantum industry traces back to a single institution, the QuTech research centre founded in 2014 by Delft University of Technology and the national applied-research organisation TNO. QuTech has acted as a startup factory, and the spinouts now span hardware, control electronics, networking, and quantum security, with most of them still located within a few kilometres of the original Delft campus. That geographic concentration produces an unusual advantage, because the netherlands quantum computing companies share a talent pool, a supplier network, and a research base that would normally be spread across an entire continent. A superconducting-processor startup such as QuantWare can buy control electronics from Qblox, cryogenic cabling from Delft Circuits, and chip-characterisation systems from Orange Quantum Systems, with every supplier sitting in the same city. The result is a vertically integrated quantum-hardware cluster that gives the Netherlands a structural edge well beyond what its size would predict. Quantum Delta NL and the national funding model Quantum Delta NL is the national coordinating organisation for the Dutch quantum sector, and it is the funding instrument that turned a strong research base into a commercial ecosystem. In 2021 the programme secured EUR 615M from the Dutch National Growth Fund, one of the largest single quantum allocations in Europe relative to national output, and the broader Quantum Delta programme now steers more than EUR 1.2B of combined public and private investment through 2027. The money is structured around catalyst programmes covering quantum computing and simulation, the quantum internet, and quantum sensing, plus a dedicated track for ecosystem development, education, and market creation. The programme now organises the country around five regional hubs in Delft, Eindhoven, Leiden, Twente, and Amsterdam. The programme is deliberately built to commercialise research rather than simply fund it, and the clearest sign of that intent is the House of Quantum, a shared facility in Delft that gives early-stage netherlands quantum computing companies laboratory space, cleanroom access, and proximity to the QuTech research base. Its investment arm, QDNL Participations, launched a EUR 60M global fund for early-stage quantum startups in 2025 to keep more of that pipeline well capitalised. Quantum Delta NL also coordinates Dutch participation in the EU Quantum Flagship, which keeps the national programme aligned with the cross-border supply chains that every Dutch hardware vendor depends on. The top netherlands quantum computing companies These ten organisations span the full Dutch quantum stack. One is the research anchor that produced most of the others (QuTech), two are quantum-processor vendors (QuiX Quantum on photonics, QuantWare on superconducting QPUs), one is a quantum-software vendor (Fermioniq), and the remaining six form a deep supply-chain and networking layer (Qblox, Single Quantum, QphoX, Delft Circuits, Orange Quantum Systems, and Q*Bird).

The Quantum Delta NL programme tracks the netherlands quantum computing companies ecosystem with annual roadmap updates and a public catalogue of participating ventures. Independent directories of the netherlands quantum computing companies list a similar shortlist of names. The profiles below cover the leading organisations in depth. QuTech (TU Delft + TNO) Quantum research institute · Delft, Netherlands · Founded 2014 QuTech is the advanced research centre founded in 2014 as a joint enterprise of Delft University of Technology and TNO, the Dutch national applied-research organisation, and it is the scientific anchor of the entire Dutch quantum ecosystem. The institute runs parallel programmes on superconducting qubits, semiconductor spin qubits, and topological qubits, and it operates Quantum Inspire, the first publicly accessible quantum-computing platform in Europe, which exposes both a five-qubit superconducting Starmon processor and a two-qubit Spin-2 semiconductor processor over the public cloud. QuTech has produced almost every Dutch quantum spinout of the past decade, including Qblox, QphoX, Orange Quantum Systems, and Q*Bird, and it sustains a long-running research partnership with Intel on silicon spin qubits and has collaborated with Microsoft on topological qubits through the Station Q Delft programme. The institute also coordinates Dutch participation in the EU Quantum Flagship and hosts the national quantum-internet demonstration network linking Delft, The Hague, and Leiden. qutech.nl → QuiX Quantum Photonic quantum processors · Enschede, Netherlands · Founded 2019 QuiX Quantum is the Enschede-based photonic-hardware vendor founded in 2019 as a spinout from the University of Twente, and it builds room-temperature quantum processors from low-loss silicon-nitride waveguide circuits rather than the cryogenic platforms used by superconducting or spin-qubit vendors. The company shipped what it describes as the largest commercially available photonic quantum processor, a 20-mode universal interferometer, and it delivered Germany its first photonic quantum computer under a contract with the German Aerospace Centre. QuiX Quantum closed a EUR 15M Series A in July 2025 led by Invest-NL, financing it to deliver a first-generation universal photonic quantum computer, and its roadmap then targets a fault-tolerant photonic machine built on a measurement-based architecture. The room-temperature operation and standard-fibre compatibility make QuiX one of the most networking-ready vendors in the Dutch ecosystem. quixquantum.com → QuantWare Superconducting QPU foundry · Delft, Netherlands · Founded 2020 QuantWare is the Delft-based superconducting-processor manufacturer founded in 2020, and it occupies an unusual position in the Dutch ecosystem because it sells quantum processing units to other quantum companies rather than operating a cloud service of its own. The product line runs from the five-qubit Soprano and the 25-qubit Contralto to the Tenor and Crescendo families, and customers buy bare QPUs to integrate into their own systems, which has made QuantWare a foundry-style supplier to research labs and startups across Europe and North America. The company’s VIO 3D-integration technology routes qubit control signals vertically through the chip rather than across its surface, which is the architectural primitive that lets a superconducting processor scale past the wiring bottleneck that constrains planar designs. In 2025 QuantWare processors powered what was reported as the Netherlands’ largest quantum computer, a system aiming at the 100-qubit mark, and the company secured EUR 7.5M from the EU EIC Accelerator to advance its VIO scaling roadmap. QuantWare positions itself as the merchant-foundry layer of the quantum-hardware supply chain. quantware.com → Qblox Quantum control electronics · Delft, Netherlands · Founded 2019 Qblox is the Delft-based control-electronics vendor spun out of QuTech in 2019, and it builds the Cluster, a modular qubit-control stack that generates and reads the microwave pulses driving superconducting, spin, and other solid-state qubits. The control layer is one of the hardest scaling problems in quantum computing because every additional qubit needs its own low-noise signal chain, and Qblox designs its hardware so that racks can be expanded without the latency penalties that constrain conventional instrumentation. The company raised a EUR 20M Series A round in 2023 led by EQT Ventures, and its systems ship to quantum-hardware groups and national labs on several continents. Qblox sits alongside Delft Circuits and Orange Quantum Systems as part of the dense Dutch control-and-measurement supply chain that surrounds the QuTech research programme. qblox.com → Fermioniq Quantum emulation software · Amsterdam, Netherlands · Founded 2021 Fermioniq is the Amsterdam-based quantum-software vendor founded in 2021, and it develops tensor-network emulation algorithms that simulate quantum circuits on classical hardware with controllable accuracy. The company’s Ava emulation engine lets researchers and enterprises test quantum algorithms at scales that would otherwise need a fault-tolerant quantum computer, and it serves as both a development tool and a benchmark that exposes where a circuit genuinely needs quantum hardware rather than classical approximation. Fermioniq raised seed and follow-on financing from European deep-tech investors and it works with QuTech and industrial partners on near-term algorithm validation. The company represents the software-and-emulation layer of the Dutch ecosystem, a layer that matters because honest classical baselines are what separate real quantum advantage from circuits that a laptop can already reproduce. fermioniq.com → Single Quantum Single-photon detectors · Delft, Netherlands · Founded 2012 Single Quantum is the Delft-based photonics-hardware vendor founded in 2012, and it manufactures superconducting nanowire single-photon detectors, the SNSPD technology that registers individual photons with high efficiency and very low timing jitter. These detectors are a core component of quantum-networking and quantum-key-distribution systems, of photonic quantum-computing experiments, and of a wider set of applications spanning LIDAR, deep-space optical communication, and life-science imaging. Single Quantum supplies detector systems to research institutes and quantum companies worldwide, and its products underpin much of the photonic experimentation done inside the QuTech quantum-internet programme. As one of the oldest companies in the Dutch ecosystem, Single Quantum anchors the detector segment of the Dutch quantum-hardware supply chain. singlequantum.com → QphoX Quantum transduction · Delft, Netherlands · Founded 2020 QphoX is the Delft-based hardware vendor spun out of QuTech in 2020, and it builds the Quantum Modem, a device that converts the microwave-frequency signals of a superconducting qubit into optical photons that can travel down standard telecom fibre. Microwave-to-optical transduction is one of the most important unsolved problems for scaling quantum computers, because superconducting processors operate at microwave frequencies that cannot travel beyond a cryostat, and networking two of them together requires a low-loss bridge into the optical domain. QphoX raised seed financing from Quantonation, Speedinvest, and other deep-tech investors, and it partners with superconducting-hardware groups on distributed quantum-computing demonstrations. The company addresses the interconnect layer that determines whether quantum data centres can ever be built from more than one fridge. qphox.eu → Delft Circuits Cryogenic I/O cabling · Delft, Netherlands · Founded 2016 Delft Circuits is the Delft-based supply-chain vendor founded in 2016, and it makes Cri/oFlex, a flexible cryogenic-cabling product that carries control and readout signals between room-temperature electronics and the qubit chip inside a dilution refrigerator. Cabling is a quietly decisive scaling constraint, because each qubit needs several signal lines, and conventional coaxial cables add bulk and heat load that limit how many qubits a single fridge can host. The Cri/oFlex ribbon design packs many channels into a low-thermal-conductivity flexible circuit, which raises the qubit ceiling of a given refrigerator. Delft Circuits supplies labs and quantum companies across Europe and North America, and it forms part of the cluster of Dutch firms that have turned cryogenic infrastructure into a distinct commercial segment of the Dutch quantum-hardware sector. delft-circuits.com → Orange Quantum Systems Quantum chip diagnostics · Delft, Netherlands · Founded 2020 Orange Quantum Systems is the Delft-based test-and-measurement vendor spun out of QuTech in 2020, and it builds automated diagnostic systems that characterise quantum chips quickly and reproducibly. As quantum-processor fabrication scales, the bottleneck shifts from making chips to verifying them, because every device has to be measured for qubit frequencies, coherence times, and gate fidelities before it can be used.

Orange Quantum Systems sells turnkey test platforms that automate this characterisation, which shortens the development loop for hardware groups and foundry-style suppliers such as QuantWare. The company partners with QuTech and other European hardware programmes, and it complements Qblox and Delft Circuits in the dense Dutch quantum-instrumentation cluster that has grown up around the Delft research base. orangeqs.com → Q*Bird Quantum key distribution · Delft, Netherlands · Founded 2022 Q*Bird is the Delft-based quantum-communication vendor spun out of QuTech and TNO in 2022, and it builds Falqon, a quantum-key-distribution system designed for cost-effective metropolitan networks. Most QKD products connect just two endpoints, but Falqon uses a central, untrusted node so that many users can share encryption keys across one network without each pair needing a dedicated link, which is the architectural feature that makes city-scale deployment economically realistic. Q*Bird ran a live trial of its technology at the Port of Rotterdam, one of the largest ports in the world, to secure logistics communications against the future threat of quantum-enabled decryption. The company sits in the quantum-security layer of the Dutch ecosystem, alongside the post-quantum-cryptography work coordinated through Quantum Delta NL. qbird.eu → MagiQware Quantum software · Delft, Netherlands · Founded 2023 MagiQware is a Dutch quantum computing startup developing AI-assisted software for magic state distillation (MSD), a step that enables fault-tolerant quantum computation. Magic state distillation is needed for quantum computers to outperform classical computers even with quantum error correction in place. MagiQware’s software automates MSD procedures, develops algorithms that need fewer qubits, and improves resource efficiency for faster quantum computation. Its tools let users carry out magic state distillation automatically, quickly, and efficiently. The company is associated with YES!Delft, a leading tech incubator in the Netherlands, and focuses on advancing practical fault-tolerant quantum computing. magiqware.com → Aluvia Photonics Photonic · Enschede, Netherlands · Founded 2022 Aluvia Photonics is a provider of photonic integrated circuits based on a proprietary aluminium oxide (AlOx/Al2O3) material platform, founded in 2022 as a University of Twente spin-off.

In May 2026, FrostByte raised EUR 1.3M in pre-seed funding led by InnovationQuarter Capital. frostbyte.nl → QT Sense Quantum sensing · Groningen, Netherlands · Founded 2024 QT Sense is a Groningen-based startup spun out from the University Medical Center Groningen (UMCG) in February 2024. It uses nanodiamond-based quantum sensing to detect changes in cellular activity at the single-cell level, with applications in disease diagnostics. The company has secured 6 million euros in funding to advance the technology. QT Sense’s flagship product, Quantum Nuova, is a single-cell Nano-MRI platform that measures cellular activity with high precision, supporting early sepsis diagnostics and personalized cancer treatment. The company says its technology can detect sepsis within seconds, which could significantly improve survival rates, and that understanding disease at the single-cell level can change how medical diagnostics are done. qtsense.nl → LioniX International Photonic · Enschede, Netherlands · Founded 2001 LioniX International is a Netherlands-based global provider of customized microsystem solutions, specializing in photonic integrated circuits (PICs) and MEMS technologies.

Where Germany ships hardware across five competing modalities and France runs three independent processor programmes, the Netherlands has chosen a narrower hardware bet, with QuiX Quantum on photonics and QuantWare on superconducting circuits as the two main processor vendors. The depth instead sits in the layers around the processor, in control electronics, cabling, detectors, transduction, diagnostics, and key distribution, which is where the bulk of the Dutch quantum companies actually operate. The supply chain is the product That structure is a deliberate strength rather than a gap. A quantum computer is a system, and the components that connect a qubit chip to the outside world are as hard to engineer as the chip itself. Qblox control stacks, Delft Circuits cryogenic cabling, Single Quantum photon detectors, and Orange Quantum Systems test platforms are sold to quantum-hardware groups worldwide, which means Dutch firms earn revenue from competitors’ processors regardless of which modality eventually wins. The Netherlands has positioned itself as the supplier layer of the global quantum industry, and that is a more defensible commercial position than betting on a single qubit type. Project HAVIK and the 100-qubit milestone The three firms now collaborate directly through Project HAVIK, a joint effort by QuantWare, Qblox, and Delft Circuits to push two-qubit gate fidelity toward the state of the art. Our report on how QuantWare powered the Netherlands’ largest quantum computer shows that supplier layer reaching the 100-qubit frontier. The networking thesis The third pattern is a clear bet on connected quantum systems rather than isolated machines. QphoX builds the microwave-to-optical bridge that lets superconducting processors talk over fibre, Single Quantum supplies the detectors that quantum networks rely on, and Q*Bird builds the key-distribution hardware that secures them. QuTech runs a physical quantum-internet testbed linking Delft, The Hague, and Leiden. Several of the Netherlands quantum computing companies are aligned around the idea that the long-term architecture is a network of modest quantum nodes, not one monolithic processor, and Dutch research has led that field for a decade. The Delft cluster and the supply-chain story The geographic heart of the Dutch quantum sector is Delft, a mid-sized city between Rotterdam and The Hague, and the concentration there is hard to overstate. QuTech sits on the TU Delft campus, and Qblox, QphoX, Orange Quantum Systems, Q*Bird, Single Quantum, QuantWare, and Delft Circuits are all either headquartered in Delft or within commuting distance of it. The House of Quantum shared facility was built in Delft for exactly this reason, to keep the next generation of Netherlands quantum computing companies inside the cluster while they are too small to run their own cleanrooms. Amsterdam adds a second pole focused on software and applications, and it is where Fermioniq develops its emulation engine and where parts of the wider quantum-algorithm and quantum-finance community sit, helped by the presence of major banks and the national research institute CWI. Enschede in the east hosts QuiX Quantum and the University of Twente photonics base, which gives the country a third regional centre anchored on integrated-photonics fabrication. The three poles are close enough, and well enough connected, that the Dutch quantum companies effectively operate as a single national cluster. Quantum Inspire and the quantum-internet programme Two QuTech programmes give the Netherlands a visible position on the global quantum map. Quantum Inspire, launched in 2020, was the first publicly accessible quantum-computing platform in Europe, and it lets anyone run circuits over the cloud on real Dutch hardware, including a five-qubit superconducting Starmon processor and a two-qubit Spin-2 semiconductor processor. The semiconductor-spin machine is notable because it made the Netherlands one of the few places in the world offering public access to a spin-qubit device, a modality that Intel and QuTech have jointly pursued for years. The quantum-internet programme is the second flagship, and it is where Dutch research is furthest ahead of the field. QuTech has demonstrated entanglement-based links between separate quantum nodes and operates a multi-node testbed connecting Delft, The Hague, and Leiden, which is among the most advanced quantum-network demonstrations anywhere. This programme is the research engine behind the networking-focused Netherlands quantum computing companies, and it explains why so much Dutch commercial activity sits in transduction, detection, and quantum key distribution rather than in raw qubit counts. When the Netherlands matters for your quantum strategy Sourcing quantum hardware components If you are building or operating quantum hardware, the Netherlands is one of the first places to look for the parts around the processor. Qblox control electronics, Delft Circuits cryogenic cabling, Single Quantum photon detectors, QuantWare superconducting QPUs, and Orange Quantum Systems diagnostic platforms are all sold internationally, and many quantum-hardware groups already depend on at least one Dutch supplier. Dutch firms have made the supply-chain layer a genuine export sector, so procurement teams should treat Delft as a primary sourcing region rather than a niche one. Photonic computing and quantum networking For organisations interested in photonic quantum computing or in distributed quantum architectures, the Dutch ecosystem is unusually deep. QuiX Quantum offers commercially available photonic processors that run at room temperature and connect to standard fibre, while QphoX and Single Quantum supply the transduction and detection hardware that distributed systems need. The QuTech quantum-internet testbed gives partners a working environment for networked-quantum research, so a quantum-networking strategy that ignores the Netherlands is missing the most mature programme in Europe. Quantum security and post-quantum readiness The Netherlands also matters for quantum-safe communication and post-quantum-cryptography planning. Q*Bird builds metropolitan-scale quantum-key-distribution hardware and has trialled it at the Port of Rotterdam, while Quantum Delta NL coordinates national work on the migration to post-quantum cryptography. Enterprises in logistics, finance, and critical infrastructure that need to plan for the eventual threat of quantum-enabled decryption will find both working hardware and policy coordination inside the Dutch ecosystem, which makes the country a useful reference point for any quantum-security roadmap.

The Dutch ecosystem is anchored by QuTech, the Delft research institute jointly run by TU Delft and TNO that operates the Quantum Inspire cloud platform and produced most Dutch spinouts. The two main processor vendors are QuiX Quantum in Enschede, which builds room-temperature photonic quantum processors, and QuantWare in Delft, which manufactures superconducting QPUs as a merchant foundry. Fermioniq in Amsterdam develops quantum-emulation software. The supply-chain and networking layer includes Qblox for control electronics, Single Quantum for single-photon detectors, QphoX for microwave-to-optical transduction, Delft Circuits for cryogenic cabling, Orange Quantum Systems for chip diagnostics, and Q*Bird for quantum key distribution. Together these ten organisations define the Netherlands quantum computing companies covered in this guide. What is Quantum Delta NL? Quantum Delta NL is the national programme that coordinates and funds the Dutch quantum sector. It secured EUR 615M from the Dutch National Growth Fund in 2021, and the broader programme now steers more than EUR 1.2B of combined public and private investment through 2027. Quantum Delta NL is organised around catalyst programmes for quantum computing and simulation, the quantum internet, and quantum sensing, plus an ecosystem track covering education, talent, and market creation. The programme deliberately focuses on commercialising research, and it built the House of Quantum shared facility in Delft to give early-stage companies laboratory and cleanroom access. It also coordinates Dutch participation in the EU Quantum Flagship. What is QuTech and why does it matter? QuTech is an advanced quantum-research institute in Delft, founded in 2014 as a joint venture between Delft University of Technology and TNO, the Dutch national applied-research organisation. It runs research programmes on superconducting qubits, semiconductor spin qubits, and topological qubits, and it operates Quantum Inspire, the first publicly accessible quantum-computing platform in Europe. QuTech matters because it functions as the engine of the entire Dutch quantum sector, and most Dutch quantum companies, including Qblox, QphoX, Orange Quantum Systems, and Q*Bird, began as QuTech spinouts. The institute also sustains long-running partnerships with Intel on silicon spin qubits and with Microsoft on topological hardware, and it leads the national quantum-internet programme. Does the Netherlands have a quantum computer the public can use? Yes. QuTech operates Quantum Inspire, which launched in 2020 as the first publicly accessible quantum-computing platform in Europe. The platform lets users run circuits over the cloud on real Dutch hardware, including a five-qubit superconducting Starmon processor and a two-qubit Spin-2 semiconductor spin-qubit processor. The spin-qubit machine is particularly notable, because it made the Netherlands one of the very few places in the world offering public cloud access to a semiconductor spin-qubit device, a modality developed jointly by QuTech and Intel. Quantum Inspire is a research and education platform rather than a commercial cloud service, but it gives Dutch companies and the wider research community a visible, hands-on national capability. What modalities do Dutch quantum companies focus on? The Netherlands quantum computing companies concentrate on two main processor modalities. QuiX Quantum builds photonic quantum processors from low-loss waveguide circuits that run at room temperature, while QuantWare manufactures superconducting QPUs. QuTech research additionally covers semiconductor spin qubits and topological qubits, and the Spin-2 processor on Quantum Inspire reflects the strong Dutch position in spin-qubit work pursued with Intel. The deeper Dutch specialism, though, is not any single qubit type but the supporting layers, with companies focused on control electronics, cryogenic cabling, single-photon detection, microwave-to-optical transduction, chip diagnostics, and quantum key distribution. That makes the Netherlands modality-agnostic at the component level even though its processor bets are relatively focused. Why is Delft so important to Dutch quantum computing? Delft is the geographic heart of the Dutch quantum sector because QuTech is located on the TU Delft campus, and almost every Dutch quantum company either spun out of QuTech or settled nearby to stay close to it. Qblox, QphoX, Orange Quantum Systems, Q*Bird, Single Quantum, QuantWare, and Delft Circuits are all in or around Delft, which creates a vertically integrated cluster where a hardware startup can source control electronics, cabling, and test systems from suppliers in the same city. Quantum Delta NL built the House of Quantum shared facility in Delft specifically to keep early-stage Netherlands quantum computing companies inside this cluster. The concentration gives the Netherlands a structural advantage in talent, supply chain, and research access. How does the Netherlands compare with Germany and France on quantum? The Netherlands competes through concentration rather than scale. Germany runs the largest continental-European quantum programme, with roughly EUR 3B in cumulative public funding and hardware across five modalities, and France runs a EUR 1.8B national plan with three independent processor programmes.

The Dutch Quantum Delta NL programme is smaller in absolute terms, but its EUR 615M Growth Fund allocation is large relative to national output, and it is unusually focused. Where Germany and France spread bets across many qubit types, the Netherlands quantum computing companies dominate the supply-chain and networking layers and lead Europe in quantum-internet research. The three national programmes are also linked through the EU Quantum Flagship and shared European supply chains. What is the Dutch quantum-internet programme? The quantum-internet programme is a QuTech research effort, supported by Quantum Delta NL, to build networks that transmit quantum information between separate quantum nodes using entanglement rather than classical signals. QuTech has demonstrated entanglement-based links between distinct quantum processors and operates a multi-node testbed connecting Delft, The Hague, and Leiden, which is among the most advanced quantum-network demonstrations in the world. The programme is the research base behind the networking-focused Netherlands quantum computing companies, and it explains why Dutch commercial activity is concentrated in transduction, single-photon detection, and quantum key distribution. The long-term goal is a quantum internet that supports secure communication and distributed quantum computing across connected nodes. Stay current.
