# Does Europe Have a Plan for Who Gets to Use Its Quantum Computers?

A TU Delft-led analysis published today argues that Europe's emerging quantum infrastructure — built largely through the OpenSuperQPlus project — is being governed by the wrong access model. As superconducting prototypes within OpenSuperQPlus scale toward operational relevance, the dominant contractual access model risks concentrating quantum compute time among well-resourced institutions and large industrial players, excluding the academic researchers, SMEs, and public-interest users the EU's own quantum strategy was designed to empower.

The core argument: access frameworks built on bilateral contracts prioritize who can pay and negotiate, not who can generate the broadest scientific or societal return. The TU Delft team proposes an alternative grounded in openness and shared benefit — criteria more analogous to how Europe funds particle physics infrastructure at CERN than how it currently allocates cloud compute time.

This matters now because the OpenSuperQPlus project, funded under the EU Quantum Flagship with a consortium spanning multiple European national labs and universities, is no longer a future promise. Functioning multi-qubit superconducting prototypes exist. The question of access governance has shifted from theoretical to urgent.

## OpenSuperQPlus: Where Europe's Superconducting Stack Currently Stands

OpenSuperQPlus is the EU Quantum Flagship's primary superconducting hardware initiative, targeting 100+ physical qubit systems with the architecture and [coherence time](https://quantumintel.tech/glossary/coherence-time) improvements necessary to run meaningful [NISQ](https://quantumintel.tech/glossary/nisq)-era algorithms and begin meaningful quantum error correction research.

The project represents a different philosophy from the US commercial model. Rather than a single corporate driver — the approach taken by [IBM Quantum](https://quantumintel.tech/companies/ibm) with its Eagle, Osprey, and Heron processor families, or [Google Quantum AI](https://quantumintel.tech/companies/google-quantum-ai) with Sycamore and Willow — OpenSuperQPlus distributes hardware development across a consortium. That structure creates genuine scientific breadth but complicates the question of who controls access once systems are operational.

The TU Delft paper identifies a governance vacuum: hardware is maturing faster than policy. Consortium partners currently default to contractual access agreements because that's the path of least institutional resistance. But contracts favor incumbents — those who already have legal teams, procurement budgets, and existing relationships with consortium members. A small quantum software startup in Warsaw or a computational chemistry group at a Portuguese university has structurally disadvantaged access under that model, regardless of the scientific quality of their proposed workloads.

## The Access Model Debate: Contracts vs. Open Benefit

The TU Delft framework proposes evaluating access requests against criteria including:

- **Scientific openness**: Is the research publishable? Are results shared with the European research community?
- **Societal benefit**: Does the application address a priority area — materials science, pharmaceutical discovery, climate modeling, cryptographic transition?
- **Capacity building**: Does the access proposal train new quantum researchers or develop reusable open-source tooling?

This is not a radical concept in European research infrastructure. CERN's Large Hadron Collider allocates beam time through peer review, not procurement. The European Spallation Source in Lund operates similarly. The argument is that quantum computers, once they reach sufficient capability, should be governed as scientific infrastructure rather than as commercial cloud services.

The counterargument — which the TU Delft analysis acknowledges — is that contractual models generate the revenue streams that fund hardware maintenance, upgrades, and the engineering staff needed to keep dilution refrigerator-based systems operational. A [dilution refrigerator](https://quantumintel.tech/glossary/dilution-refrigerator) operating at 10–15 millikelvin doesn't run itself, and the operational costs of superconducting quantum systems are substantial. CERN-style open access works when governments fund operations directly and continuously. Europe's quantum funding landscape, while significant at roughly €1 billion committed through the Quantum Flagship, has not yet committed to that level of sustained operational subsidy.

## What the TU Delft Team Is Actually Proposing

The framework is not purely academic. It outlines a tiered access model:

**Tier 1 — Open Research Access**: Allocated via peer-reviewed application, free at point of use, targeted at academic and public-sector researchers. Results must be published open-access.

**Tier 2 — Collaborative Industrial Access**: Available to private-sector users who co-develop benchmarks, contribute to open software stacks, or partner with academic institutions. Subsidized pricing, results may be kept proprietary for a defined embargo period.

**Tier 3 — Commercial Access**: Full-cost contractual access for commercial applications, with revenue recycled into Tier 1 and Tier 2 subsidies.

This structure mirrors models used in synchrotron light sources and supercomputing centers across Europe. The PRACE supercomputing network, which allocated HPC time across EU member states before transitioning to EuroHPC, provides a direct precedent. The analysis explicitly cites EuroHPC as a governance template.

The proposal also addresses [quantum advantage](https://quantumintel.tech/glossary/quantum-advantage) benchmarking: access allocation should partly track demonstrated utility, not just qubit count. A 50-qubit system with high [gate fidelity](https://quantumintel.tech/glossary/gate-fidelity) and long coherence times may deliver more useful computation than a 200-qubit system with poor [error threshold](https://quantumintel.tech/glossary/error-threshold) performance. The framework recommends standardized benchmarking — including [CLOPS](https://quantumintel.tech/glossary/clops) and [logical qubit](https://quantumintel.tech/glossary/logical-qubit) performance metrics — as prerequisites for public access allocation, forcing transparent hardware characterization.

## The Sovereignty Dimension

The framing as "quantum sovereignty" is deliberate and politically loaded. European digital sovereignty concerns — most visibly in cloud infrastructure, where AWS, Microsoft Azure, and Google Cloud dominate — have driven substantial policy energy since 2020. The GAIA-X initiative, whatever its execution failures, reflected genuine anxiety about European dependency on US-headquartered infrastructure for strategically sensitive compute.

Quantum computing represents a chance to avoid repeating that pattern. Europe has genuine hardware depth: [IQM Quantum Computers](https://quantumintel.tech/companies/iqm-quantum-computers) in Finland is shipping superconducting systems to national labs; [Alpine Quantum Technologies (AQT)](https://quantumintel.tech/companies/alpine-quantum-technologies) in Innsbruck is advancing trapped-ion platforms; [QuiX Quantum](https://quantumintel.tech/companies/quix-quantum) in the Netherlands is building photonic processors. The research base — TU Delft, ETH Zurich, LMU Munich, the University of Copenhagen — is world-class.

But hardware capability without access governance is incomplete sovereignty. If European quantum systems are primarily accessible to the same large multinationals that dominate classical cloud, or if the best European quantum research groups route their work through US commercial platforms because access is easier, the strategic case for EU quantum investment weakens considerably.

The TU Delft proposal is, at its core, an argument that sovereignty requires deliberate access architecture — not just domestic hardware.

## Skeptical Reading: What the Framework Doesn't Solve

The analysis is rigorous on principles but lighter on operational mechanics. Several tensions remain unresolved:

**Peer review latency**: Scientific peer review for access allocation takes weeks to months. Quantum hardware development cycles and experimental needs don't always accommodate that timeline. The paper gestures toward fast-track mechanisms but doesn't specify them.

**Defining "societal benefit"**: This criterion is philosophically sound but practically contested. Who sits on the access committee? How are conflicts of interest between consortium members and applicants managed? The history of European research infrastructure governance includes enough examples of capture by incumbent institutions to warrant skepticism here.

**The revenue shortfall**: The tiered model assumes Tier 3 commercial revenue will be sufficient to cross-subsidize Tiers 1 and 2. That assumption depends on European quantum systems achieving commercial relevance on a timeline that remains uncertain. If systems spend the next three years primarily in the NISQ regime without clear commercial quantum advantage, Tier 3 revenue may be thin.

**Competition with US platforms**: A European researcher choosing between six months of peer-review-gated access to an OpenSuperQPlus system and immediate cloud access to IBM Quantum's latest Heron processors or [Quantinuum](https://quantumintel.tech/companies/quantinuum)'s H-series trapped-ion systems may rationally choose speed over sovereignty. The framework needs to account for the competitive pressure from incumbent commercial platforms.

## Industry Trajectory Implications

This paper arrives at a moment when quantum access governance is becoming a first-order policy question globally, not just in Europe. In the US, DARPA's Underexplored Systems for Utility-Scale Quantum Computing (US2QC) program and the National Quantum Initiative's renewed push both grapple with similar questions about who benefits from publicly-funded quantum research. In China, nationally-directed quantum programs operated through entities like the Chinese Academy of Sciences have long embedded access control within strategic planning.

Europe's contribution — if the TU Delft framework influences actual Quantum Flagship policy — could be a model that explicitly encodes scientific openness and broad societal benefit as access criteria rather than afterthoughts. That would be a meaningful differentiation from both the US commercial model and the Chinese state-directed model.

For quantum software companies and algorithm developers — firms like [Multiverse Computing](https://quantumintel.tech/companies/multiverse-computing) or [Riverlane](https://quantumintel.tech/companies/riverlane) operating within the European ecosystem — a well-structured open access tier would be commercially valuable. Cheaper access to European hardware reduces dependence on US cloud platforms and enables the kind of iterative benchmarking that advances both science and commercial development simultaneously.

For hardware vendors, the tiered model is a double-edged proposition: Tier 3 commercial revenue provides sustainability, but the peer-review structure for Tier 1 could slow feedback loops with the research community that drives hardware improvement.

The next critical milestone is whether the OpenSuperQPlus consortium formally adopts, modifies, or rejects this framework before its next hardware generation reaches operational status. Watch for Quantum Flagship governance meetings in Q3 2026.

## Frequently Asked Questions

**What is OpenSuperQPlus and why does it matter for European quantum access?**
OpenSuperQPlus is the EU Quantum Flagship's primary superconducting quantum hardware initiative, targeting 100+ physical qubit systems built across a pan-European research consortium. It matters for access policy because it represents Europe's most significant domestically-developed quantum computing infrastructure — and the governance decisions made now about who can use it will shape whether European quantum capacity serves broad scientific and economic goals or concentrates among a small number of large institutions.

**How does the TU Delft access framework differ from current quantum cloud models?**
Current commercial quantum cloud platforms — IBM Quantum, AWS Braket, Azure Quantum — allocate access primarily through pay-per-use or subscription contracts. The TU Delft framework proposes replacing or supplementing this with merit-based peer review for academic users, structured collaboration requirements for industrial users, and transparent benchmarking as a precondition for access. The philosophical difference is treating quantum computers as scientific infrastructure rather than commercial services.

**What is European quantum sovereignty and why is quantum computing relevant to it?**
European quantum sovereignty refers to Europe's strategic goal of maintaining independent capability in quantum technologies — hardware, software, and access — rather than depending on US or Chinese platforms for strategically sensitive computation. Quantum computing is relevant because, unlike classical cloud infrastructure where European dependency is already entrenched, quantum computing is early enough in its development that deliberate governance choices can shape who controls access to future capability.

**What are the main weaknesses of the proposed framework?**
The framework faces three primary challenges: peer-review timelines may be too slow for iterative experimental research; the "societal benefit" criterion is difficult to operationalize without risking capture by incumbents; and the revenue model assumes sufficient commercial demand to cross-subsidize open access, which depends on European systems achieving commercial quantum advantage on an uncertain timeline.

**Which European quantum hardware companies are relevant to this access debate?**
The most directly relevant players are those whose hardware may fall under or benefit from open access frameworks: IQM Quantum Computers (superconducting systems deployed at European national labs), Alpine Quantum Technologies (trapped-ion systems at the University of Innsbruck), and QuiX Quantum (photonic processors in the Netherlands). Software and algorithm companies including Multiverse Computing and Riverlane would benefit from open access tiers that reduce their dependence on US cloud platforms for hardware time.
