Europe’s most concrete bet on quantum manufacturing sovereignty has begun producing actual hardware components — and the mechanism that could make it transformative is not the €50 million (approximately $56 million USD) budget or the 28-partner consortium, but a plan to publish open Process Design Kits that would allow any startup or university lab to design neutral-atom quantum components without running a cleanroom. Pasqal confirmed the consortium’s active build-out in an October 6, 2026 press release, three months after the project’s formal Brussels kick-off.

Execution Confirmed: From Ambition to Active Build-Out

Three months after Q-PLANET’s formal July 8–9 kick-off in Brussels, Pasqal (Nasdaq: PSQL) issued a press release on October 6 confirming that the consortium has moved from planning into active component development. “Three months after our kick-off in Brussels, Q-PLANET has moved from ambition to execution,” said Loïc Henriet, CTO of Pasqal, in the statement.

Q-PLANET — Quantum Pilot Line for production of Advanced chips for Neutral atom European Technologies — is one of six European Quantum Chip Stability Pilot Lines co-funded by the EU’s Chips Joint Undertaking (Chips JU) and national and regional authorities across 11 member states.

What Q-PLANET Is Actually Building

The initiative is not building quantum computers. It is building the industrial-grade components that quantum computers require but that until now have been produced almost entirely by hand in research laboratories: precision laser sources, microfabricated atom chips, and vapor cells. The transition from custom laboratory assemblies to high-volume manufacturing has been blocked by the absence of standardized manufacturing control loops and calibration baselines. Q-PLANET addresses this directly.

Laser-on-chip systems. The consortium is fabricating integrated laser sources and amplifiers at four wavelengths critical to neutral-atom qubit operation: 461 nm (strontium first-stage cooling), 698 nm (strontium clock transition for qubit manipulation), 795 nm (rubidium D1 line and sensing applications), and 1013 nm (strontium/ytterbium near-infrared for state preparation). Pasqal leads the 1013 nm chip-based laser work and is integrating components at 795 nm and 1013 nm into its own commercial quantum processing units (QPUs).

Advanced atom chips. The project is designing microfabricated planar chips for atomic containment — reducing the physical footprint and power demands currently required by scalable QPU architectures. Laboratoire Temps Espace (SYRTE) is leading the atom chips work package. The Laboratoire Albert Fert, a CNRS-Thales joint research laboratory on the Thales Research and Technology site in Palaiseau, hosts a second atom chip production center. Thales contributes design, testing, foundry, and quantum provider capabilities for atom chips and hosts the third packaging and testing center for atom chips.

Microfabricated vapor cells. Used in atomic clocks and high-precision field sensors, these components extend Q-PLANET’s relevance beyond computing into quantum sensing and secure communications.

Why Open PDKs Change the Equation

The most strategically significant element of Q-PLANET is not the components themselves but the plan to publish open Process Design Kits (PDKs) and Assembly Design Kits (ADKs).

In the conventional semiconductor industry, PDKs are the foundational infrastructure that enabled the fabless model: a software environment encoding a foundry’s process parameters, design rules, and device models so that chip designers can create and simulate designs without needing to run a factory themselves. Open PDKs such as SkyWater’s SKY130, released in 2020, subsequently allowed universities and startups to tape out real silicon on production processes without cleanroom access of their own.

Q-PLANET’s stated goal is to replicate this dynamic in the neutral-atom quantum hardware sector. If open PDKs for laser-on-chip systems, atom chips, and vapor cells are published and validated against real production runs, any European engineering team will be able to design quantum hardware components and send them to a partner foundry without needing to build atomic physics infrastructure. “Design and assembly standards will also be established to facilitate access to the neutral-atom quantum technology sector for start-ups and small and medium-sized enterprises,” according to Politecnico di Milano, one of the consortium partners.

This analogy has limits. A classical PDK describes a well-characterized process node with decades of industrial history. Quantum PDKs must simultaneously encode geometric manufacturability, electromagnetic behavior, quantum dynamics, material loss, and decoherence noise — a fundamentally more complex design space. Experts at OrangeQS have argued that quantum PDKs must additionally include a Process Control Kit to address the difficulty of directly observing quantum device performance at scale. The PDK ambition is real; whether it materializes on the timeline Q-PLANET implies remains to be validated.

A Distributed, Cross-Border Foundry Network

The consortium distributes manufacturing responsibilities across specialized centers to build supply chain resilience across Europe.

The Technical University of Denmark (DTU) — drawing on DTU Nanolab’s cleanroom infrastructure — serves as the passive optical element foundry for the 461 nm and 795 nm laser bands. VTT Technical Research Centre of Finland leads packaging activities, acts as foundry and test partner for silicon nitride passive optical elements at 1013 nm, and co-hosts the modular backend pilot line with DTU.

TopGaN and the Institute of High Pressure Physics of the Polish Academy of Sciences (Unipress) manage the design, wafer-level characterization, and processing of gallium nitride emitters for the 461 nm blue laser lines — a III-V semiconductor process unavailable in standard CMOS or silicon nitride fabs. III-V Lab provides parallel design and foundry support for the 795 nm and 1013 nm architectures.

The Istituto Nazionale di Ricerca Metrologica (INRiM) in Italy leads noise and linewidth validation testing across all four wavelengths. iQrypto is building a standardized Linux API and middleware layer over its Aquila software stack, providing a uniform software interface for the high-speed electronic modulators and FPGA-driven pulse controllers that manage the quantum components.

ICFO (Institut de Ciències Fotòniques) in Spain participates as a quantum technology provider and as one of the program’s key testing sites, with its Atomic Quantum Optics group (Prof. Morgan Mitchell), Ultracold Quantum Gases group (Prof. Leticia Tarruell), and quantum memory and network group (Prof. Hugues de Riedmatten) engaged in validating components at relevant wavelengths.

The integrated components will be validated on active platforms including Pasqal’s commercial neutral-atom QPUs, the University of Stuttgart’s QRydDemo demonstrator, and Welinq’s quantum memory nodes. The program is targeting maturation from Technology Readiness Level 4 (technology validated in lab) to TRL 6 (technology demonstrated in relevant environment) across its component portfolio over the three-year phase.

How Neutral-Atom Quantum Computing Actually Works

Understanding what Q-PLANET is industrializing requires understanding the mechanism these components serve. Neutral-atom quantum processors — the type built by Pasqal, QuEra, and Atom Computing — trap individual atoms (typically rubidium-87, strontium-87, or ytterbium-171) using tightly focused laser beams called optical tweezers. Each tweezer holds exactly one atom, enforced by light-assisted collisions that eject atom pairs until a single atom remains.

Qubit states are encoded in two hyperfine ground-state energy levels of each atom. Two-qubit logic gates are performed via “Rydberg blockade”: atoms are briefly excited to Rydberg states — high-energy shells where van der Waals interactions between adjacent atoms are strong enough that only one atom in a pair can be excited simultaneously. This conditional behavior produces the controlled-NOT-equivalent gate that quantum circuits require. After the gate, atoms return to the ground state and are read out via fluorescence imaging.

The competitive advantage of neutral atoms over superconducting qubits (IBM, Google) and trapped-ion systems (IonQ) is threefold: atoms are naturally identical (no fabrication-induced variation between qubits), connectivity is reconfigurable by repositioning tweezers between circuit layers (unlike fixed-coupling superconducting architectures), and coherence times can reach 40 seconds on some platforms. Caltech demonstrated an optical tweezer array of 6,100 atoms in September 2025.

Q-PLANET’s laser-on-chip work is building the photonic integrated circuit infrastructure needed to replace the large bulk free-space optics that currently make neutral-atom QPUs physically large and commercially cumbersome. Replacing free-space laser beams with chip-scale integrated sources is the engineering step that would allow QPUs to approach the kind of form factor suitable for data center deployment.

Pasqal’s Broader Context

The Q-PLANET execution announcement arrived six weeks after Pasqal completed its business combination with Bleichroeder Acquisition Corp. II, with shareholders approving the merger on August 25, 2026. Pasqal shares began trading on the Nasdaq on August 28 under the ticker symbols PSQL and PSQLW. The transaction left the combined company with approximately $360 million in cash — the largest cash position of any European quantum computing company at its founding as a public entity, representing roughly a third of the entire European quantum sector’s annual private funding.

Pasqal is co-founded by Nobel laureate Alain Aspect — who won the 2022 Nobel Prize in Physics for his foundational experiments on quantum entanglement — and is part of both the IBM Quantum Network and Nvidia’s ecosystem for classical HPC integration. The company has delivered three QPUs to European High-Performance Computing centers: at TGCC (France), Forschungszentrum Jülich (Germany), and CINECA (Italy). Pasqal is the elected European Convenor of CEN/CENELEC JTC22 European standardization working group on quantum computing and simulation, representing 34 European countries.

The company is simultaneously executing on three fronts: commercializing its current QPU offering, advancing toward fault-tolerant systems, and — through Q-PLANET — helping to build the European supply chain infrastructure on which the next generation of neutral-atom hardware will depend. Pasqal generated €16.5 million in revenue in 2025 (approximately $18.5 million USD) and remains unprofitable.

What This Means in the Broader Race

Europe entered 2026 attracting only about 5% of global private quantum investment, compared with more than 50% flowing to US firms. The European Quantum Industry Consortium has warned that without stronger domestic manufacturing capacity, the continent will remain dependent on non-European suppliers for the technologies it is trying to commercialize. The EU Quantum Act, expected to be proposed later in 2026, is intended to address structural funding gaps and supply-chain vulnerabilities through binding legislation — though the original Q2 2026 window has narrowed.

Q-PLANET is one of six quantum chip pilot lines launched by the Chips JU, each targeting a different hardware modality: superconducting, photonic, ion-trap, semiconductor, diamond, and neutral-atom. The collective goal is to move Europe from scientific leadership to industrial manufacturing capacity across all major quantum hardware platforms.

The European Commission’s Quantum Europe Strategy, released July 2, 2025, targets quantum computers with approximately 100 error-corrected qubits by 2030 and thousands by 2035. Pilot lines like Q-PLANET are the mechanism identified to close the gap between those targets and current laboratory capabilities.

Risks and Open Questions

The PDK ambition is the initiative’s most significant bet — and its most uncertain one. Building classical semiconductor PDKs took decades and required converging on stable process nodes that could be characterized precisely. Quantum hardware is not yet stable in that sense: decoherence noise, atom-loss rates, and gate fidelities vary between fabrication runs in ways that are difficult to model and harder to standardize. Whether the consortium can publish open PDKs that real external users find reliable will be the clearest test of whether the pilot-line model works.

A second phase of Q-PLANET is already anticipated beyond the initial three-year program, focused on expanding user adoption and further maturing the technologies developed in the first stage. Whether that trajectory holds will depend on whether the consortium delivers validated, reproducible components by approximately 2029 — and on whether the open PDK and ADK frameworks attract the broader ecosystem participation they are designed to encourage.

Frequently Asked Questions

What is a quantum Process Design Kit (PDK), and why does Q-PLANET’s plan to publish open ones matter?

In the conventional semiconductor industry, a PDK is a software package that encodes a foundry’s manufacturing parameters — design rules, device models, layer definitions — so that chip designers can create and simulate circuits without operating a fab. Open PDKs, like SkyWater’s SKY130 released in 2020, allowed universities and startups to design real chips without cleanroom access. Q-PLANET’s goal to publish open PDKs and Assembly Design Kits (ADKs) for neutral-atom quantum components aims to replicate that dynamic in quantum hardware: any European team would be able to design quantum chips and send them to a partner foundry. This matters because it could transform quantum hardware design from a capability restricted to a handful of well-funded labs into something accessible to the broader academic and startup ecosystem — the same structural shift that created the fabless semiconductor industry.

Why do neutral-atom quantum computers require specialized laser sources at four specific wavelengths?

Neutral-atom QPUs trap individual atoms using tightly focused laser beams called optical tweezers, and then manipulate those atoms’ quantum states using precisely tuned light. The four wavelengths Q-PLANET is targeting — 461 nm, 698 nm, 795 nm, and 1013 nm — correspond to specific electronic transitions in strontium and rubidium atoms: the first-stage cooling transition, the ultra-narrow clock transition used for qubit manipulation, and the readout transition. Each wavelength requires a different laser architecture and material platform (gallium nitride for 461 nm blue lines; silicon nitride for the longer wavelengths), which is why a coordinated multi-partner consortium is needed to cover the full stack.

How does Q-PLANET fit into Europe’s broader quantum strategy?

Q-PLANET is one of six quantum chip pilot lines co-funded by the EU’s Chips Joint Undertaking, each targeting a different hardware modality. Together, they form Europe’s industrial response to the observation that the continent produces world-class quantum science but currently lacks the standardized manufacturing processes needed to turn that science into commercial hardware. The European Quantum Strategy (released July 2025) targets approximately 100 error-corrected qubits by 2030 and envisions a European Quantum Act — expected to be proposed in 2026 — to create a binding legislative framework for those goals. Q-PLANET represents the neutral-atom pillar of that strategy, specifically addressing the supply chain gap that exists today in laser components, atom chips, and vapor cells.

What is Pasqal’s specific role in Q-PLANET compared with its commercial QPU business?

Pasqal coordinates Q-PLANET and leads the technical work on chip-based laser sources at 1013 nm. It also serves as a key end-user of the components the consortium produces, providing specifications for laser sources and vapor cells that will be tested and validated on Pasqal’s commercial QPUs. This dual role — both coordinator and customer — gives Pasqal a direct incentive to ensure the manufactured components meet real-world QPU requirements rather than laboratory benchmarks alone. Separately, Pasqal’s commercial operations include seven QPUs deployed globally, a Nasdaq listing (PSQL) with approximately $360 million in post-merger cash, and customer relationships with Saudi Aramco, Crédit Agricole CIB, and LG Electronics.
