Europe's Quantum Moment: Why €1.5 Billion Changes the Conversation

Private capital does not move at 170% annual growth without a reason. The reason here is convergence: the European Quantum Flagship programme has committed over €1 billion since 2018, more than €11 billion in combined EU and member-state public funding has been directed into the sector over the past five years, and the engineering results are now good enough to attract serious Series A and B rounds.

The signal from the VC side is equally clear. Quantonation, Europe's leading quantum-focused fund, closed €220 million in February 2026, one of the largest dedicated quantum vehicles in the world. Danish fund 55 North is targeting €300 million for a vehicle that would be the largest of its kind. Europe is not waiting for American capital to validate its quantum bets; it is building the infrastructure to fund them itself.

What is being built matters as much as the money. Quantum computing is not a software feature. It is physical infrastructure: machines that manipulate individual atoms and photons to solve problems that classical computers cannot. Europe's position in the computing and frontier technology sector is being shaped right now, and the funding record is a lagging indicator of the technical progress that preceded it.

Terra Quantum: Hybrid Algorithms at Scale

Terra Quantum

| St. Gallen, Switzerland / Munich, Germany

Technology: Hybrid quantum-classical algorithms that outperform classical-only methods across optimisation, routing, and simulation tasks. Terra Quantum builds the software layer that makes today's imperfect quantum hardware commercially useful without waiting for fault-tolerant machines.

Customers/Applications: Financial institutions (portfolio optimisation), logistics operators (routing at scale), and industrial enterprises seeking computational advantage on real-world constraint problems.

Funding: Terra Quantum has agreed a non-binding letter of intent for a $3.25 billion SPAC transaction to go public, signalling the company's readiness to compete at global scale. The deal would be one of the largest quantum technology listings to date.

Why it matters: Most quantum companies talk about hardware roadmaps measured in decades. Terra Quantum is building revenue today by running hybrid algorithms on existing hardware, compressing the path from research to commercial return.

➔ Founder and CEO Markus Pflitsch brings both the technical depth and the commercial ambition to make this category real. He will be speaking at DTM26.

Phasecraft: The Algorithms That Make Quantum Useful Now

Phasecraft

| Oxford and Bristol, UK (with Washington D.C. operations)

Technology: Hardware-agnostic quantum algorithms for materials simulation, energy network optimisation, and biological research. Phasecraft's algorithms make materials simulation millions of times more efficient on today's Noisy Intermediate Scale Quantum (NISQ) devices, without requiring perfect hardware.

Customers: Johnson Matthey (specialty materials development), Oxford PV (solar cell simulation), the UK's National Energy System Operator (NESO), and BT (telecoms optimisation). Hardware partnerships include Google Quantum AI, IBM, Quantinuum, and QuEra.

Funding: $34 million Series B, closed 2 September 2025, co-led by Plural, Playground Global, and Novo Holdings' Quantum Fund (its first direct quantum software investment). Total raised: over $50 million including grant funding. In March 2026, Phasecraft joined DARPA's Quantum Benchmarking Initiative.

Why it matters: Phasecraft is solving the problem that stalls most quantum deployments: making imperfect, near-term hardware useful for real industrial problems. Drug discovery timelines, materials discovery, and grid optimisation are all in scope today, not in 2035.

➔ Co-Founder Toby Cubitt, one of the world's foremost quantum algorithms researchers, will be speaking at DTM26. UCL and the University of Bristol produced the scientific foundation this company is built on.

planqc: Germany's Neutral Atom Bet

planqc

| Garching near Munich, Germany

Technology: Neutral atom quantum computers built on atoms trapped in optical lattices, artificial crystals of light. Full-stack from hardware to quantum operating systems to applications, covering the entire value chain. The approach enables hundreds of qubits with flexible 2D and 3D connectivity, well suited for quantum simulation and optimisation.

Customers/Partners: German Aerospace Centre (DLR), Leibniz Supercomputing Centre (LRZ), Airbus, ESA, Fraunhofer institutes, and d-fine. Applications span materials discovery, climate modelling, and mobility optimisation.

Funding: €50 million Series A (October 2024), led by CATRON Holding and the DeepTech and Climate Fonds (DTCF). A prior €29 million contract from DLR to build Germany's first digital neutral-atom quantum computer. Total funding and contracts secured: over €80 million.

Why it matters: The MAQCS project, currently under development, will deliver a 1,000-qubit quantum computer to the Leibniz Supercomputing Centre by 2026. Three quantum computers are already built or under development. This is not a roadmap on a slide deck.

➔ planqc was founded in 2022 as the first spin-off from the Max Planck Institute of Quantum Optics within the Munich Quantum Valley. CEO and Co-Founder Alexander Glätzle will be on stage at DTM26.

QuantumDiamonds: Building Bavaria's ASML

QuantumDiamonds

| Munich, Germany

Technology: Quantum sensing using Nitrogen-Vacancy (NV) centres in diamond to inspect semiconductor chips at a level of detail classical methods cannot reach. Quantum Diamond Microscopy (QDM) gives chip manufacturers layer-specific insight into current paths inside packaged chips, without opening them.

Customers/Applications: Semiconductor fabs and chip manufacturers requiring inspection tools for heterogeneous integration, where classical metrology methods are reaching their physical limits. The Munich facility will supply quantum-grade diamond sensors and QDM systems to global fabs.

Funding: €152 million investment announced in December 2025 to build the world's first production facility for quantum-based semiconductor inspection systems in eastern Munich, supported under the European Chips Act. The site combines sensor manufacturing, cleanrooms, and application labs.

Why it matters: As chip architectures grow more complex and heterogeneous, the inspection problem becomes existential. QuantumDiamonds is building the tool the semiconductor industry needs, and building it in Germany, with European intellectual property and talent.

➔ CEO and Co-Founder Kevin Berghoff described the Munich facility as "our transition from research to global production." Some in the industry already call it Bavaria's ASML. He will be speaking at DTM26.

Why Munich Is Becoming Europe's Quantum Capital

Three of the four companies above are rooted in Munich. That is not coincidence. Munich Quantum Valley, the Max Planck Institute of Quantum Optics, the Technical University of Munich, and the Leibniz Supercomputing Centre have collectively created the talent density, research infrastructure, and public-private funding mechanisms that quantum hardware and sensing companies need to grow.

Terra Quantum operates across St. Gallen and Munich; planqc and QuantumDiamonds are both Munich-founded. The city is doing for quantum what it did for automotive engineering: building a network deep enough to sustain an entire industry. This geographic concentration matters for investors and corporates alike, because quantum is not a sector you track from a distance.

The technical differentiation between approaches, superconducting, neutral atom, photonic, NV-centre sensing, requires proximity to the research and the founders. Explore the Securing the Quantum Era analysis for context on Europe's quantum security layer, and Bosch's Bet on Founder-Led Ventures for the corporate innovation angle on quantum.

Meet These Founders at Deep Tech Momentum 2026

Markus Pflitsch, Toby Cubitt, Alexander Glätzle, and Kevin Berghoff will all be on stage at Deep Tech Momentum 2026. The event brings together 3,000+ VCs, corporate innovation leaders, and deep tech founders at Wilhelm Studios Berlin on 20 and 21 May 2026. Quantum is not a side topic at DTM26: it is a core strand of the programme.

The quantum speakers at DTM26 represent four distinct approaches to the same underlying opportunity: applying quantum physics to industrial problems before the full fault-tolerant era arrives. Meeting them in person, in the same room as the investors and corporates actively deploying capital into the sector, is a different kind of due diligence. Check the relevant sessions at DTM26 to plan your two days.
