Germany Deploys First Laser-Free Trapped-Ion Quantum Computer Inside Major Supercomputing Facility - Tech Times

By Caleb Pittmann Published: Sep 04 2026, 10:57 AM EDT Eleqtron.com Germany has switched on a quantum computer that controls its qubits with microwaves rather than lasers — a hardware distinction that, for the first time, allowed engineers to wire a gate-based trapped-ion system directly into one of Europe's most powerful supercomputers without the vibration-sensitive optical infrastructure that has historically kept such machines confined to specialty physics labs. On September 3, 2026, Forschungszentrum Jülich and the Siegen-based startup eleQtron officially inaugurated JION at JSC — the Jülich trapped-ION quantum computer — at the Jülich Supercomputing Centre (JSC) in North Rhine-Westphalia (NRW).The inauguration ceremony, held before NRW Minister-President Hendrik Wüst, Economics Minister Mona Neubaur, and Science Minister Ina Brandes, was also the occasion for two additional funding announcements: approval of a successor project called SQALING and a second project called Q-STAR.NRW, each receiving up to approximately €25 million (approximately $29 million USD) from EU structural funds and NRW state support, signaling that JION is a waypoint in a multi-step regional quantum computing strategy. Both successor programs were announced at the ceremony alongside the JION inauguration itself.Prof. Kristel Michielsen, who heads the Jülich Supercomputing Centre and leads the JUNIQ platform, described the system's role in measured terms. "JUNIQ provides access to a range of quantum computers and allows their performance to be compared," she said at the inauguration. "With JION, we are expanding this unique user platform to include a trapped-ion system from North Rhine-Westphalia and connecting it to our HPC infrastructure — for research and industrial applications."Prof. Astrid Lambrecht, Chair of the Board of Directors at Forschungszentrum Jülich, noted the broader intent: "In doing so, we are creating the conditions for combining quantum computing and high-performance computing, allowing us to use quantum computing to address specific problems in research and industry."What JION Actually Does Differently: Microwaves Instead of LasersThe machine at the center of yesterday's ceremony belongs to the trapped-ion family of quantum computers, a class whose signature strengths — extraordinarily high gate fidelity and long qubit coherence times — have made it one of the two most credible paths toward fault-tolerant quantum computing. What makes JION and eleQtron unusual within that family is the mechanism they use to address and entangle qubits.In a conventional trapped-ion quantum computer, tightly focused laser beams strike individual ions in the trap, coupling the ions' internal quantum states to their shared vibrational motion. That coupling is the mechanism by which two-qubit entangling gates are performed — the computational backbone of every quantum circuit. Laser-based control is exquisitely precise, which is one reason Quantinuum's H-series and IonQ's systems have led the field in published gate-fidelity metrics. But it is also optically complex: the laser stack requires precise alignment, vibration isolation, and an engineering overhead that grows more burdensome as qubit counts increase.JION instead uses MAGIC — Magnetic Gradient Induced Coupling — a technology developed at the University of Siegen by Prof. Christof Wunderlich, one of eleQtron's three co-founders. The principle: by applying a static magnetic field gradient across the linear chain of ytterbium-171 (¹⁷¹Yb⁺) ions in the trap, each ion acquires a slightly different resonance frequency — a consequence of the Zeeman effect, which causes atomic energy levels to shift in response to magnetic fields. With adjacent ions offset from each other by roughly 3–5 megahertz in frequency space, they can be individually addressed by microwave pulses at 12.64 gigahertz.

Arbitrary Waveform Generators using Direct Digital Synthesis technology generate the multi-tone signals needed to drive multiple qubits simultaneously, with a timing resolution of 6.4 nanoseconds.Two-qubit entangling gates in MAGIC work through the same phonon-bus mechanism as laser-based trapped-ion systems — the ions' collective vibrational modes serve as a coupling channel — but it is microwave fields amplified by the magnetic gradient effect, rather than laser photons, that drive the state-dependent force. The result, according to research from the Wunderlich group and eleQtron, is Bell state fidelities of approximately 99.7%. That figure is below the 99.9% threshold Quantinuum reports for its systems and the 99.99% two-qubit gate fidelity IonQ demonstrated in October 2025 using its Electronic Qubit Control technology — a separate microwave-based approach that integrates qubit control onto standard semiconductor chips. The fidelity gap is real and matters for fault-tolerant computing, where higher physical-qubit fidelity directly reduces the number of physical qubits needed to encode each error-corrected logical qubit.What Does "Laser-Free" Gain You, Engineering-Wise?The tradeoffs run in both directions, but MAGIC's engineering advantages are concrete. Eliminating the laser stack removes a major source of operational complexity for large trapped-ion systems. According to technical documentation from eleQtron's hardware partners, the microwave approach consumes roughly one-fifth the power of competing laser-based designs. The ion trap itself operates at room temperature, because what requires cryogenic cooling is the qubit's quantum state preparation — handled by laser cooling of the ions — not the trap hardware. This contrasts sharply with superconducting qubit platforms, where the entire processor operates at approximately 15 millikelvin and requires a dilution refrigerator that effectively defines the size and cost of the system.The deeper implication, not explicitly stated by eleQtron but evident from the architecture, is that MAGIC's path to scaling runs through chip integration rather than laser engineering. In 2023, eleQtron partnered with Infineon Technologies to jointly develop three generations of progressively improved ion-trap chips adapted to the MAGIC concept. The target is ion-trap hardware fabricated using standard semiconductor processes — chips that could, in principle, be deployed in settings that look more like a data center than a laser laboratory. Prof. Winfried Hensinger of the University of Sussex, working independently of eleQtron, presented at the Asian Conference on Trapped Ions in April 2026 on microchips capable of generating magnetic field gradients in excess of 100 Tesla per meter (328 feet per meter), demonstrating that the microwave-on-chip direction is being pursued across multiple research groups worldwide, not just at Siegen.JION Inside JUNIQ: First Gate-Based Trapped-Ion System in a Supercomputing FacilityThe strategic significance of JION extends beyond the machine itself. JSC has spent years building JUNIQ — the Jülich UNified Infrastructure for Quantum computing — a platform that connects diverse quantum systems to the center's classical supercomputing resources, most prominently JUPITER, currently ranked among Europe's fastest supercomputers. JUNIQ allows computational tasks to be divided across classical and quantum processors — what researchers call hybrid quantum-classical or HPC-QC computing — routing to the quantum system only the subroutines for which quantum processing offers a potential advantage.JION is the first gate-based trapped-ion quantum computer to be integrated into this infrastructure. Earlier systems in JUNIQ have included a D-Wave quantum annealer (a different category, optimized only for certain classes of problems) and several superconducting-qubit experimental systems from the QSolid consortium. JION's gate-based architecture can run any quantum algorithm, not just optimization problems suited to annealers, which broadens the range of hybrid workloads JSC's user base can test.The application domains JSC is targeting include optimization problems in logistics, transport, and process engineering; simulations in physics, chemistry, biology, and materials science; and machine learning workloads. JSC has positioned JION as a production resource open to researchers and industry users, not merely a technology demonstrator.How Did JION Get Here: EPIQ, eleQtron, and a €57 Million Bet on Microwave QuantumJION's lineage traces to the EPIQ project (a development partnership for trapped-ion quantum computers in NRW), announced in March 2024 when JSC and eleQtron agreed to jointly develop a modular quantum-classical supercomputer. The NRW Ministry of Culture and Science committed approximately €21 million (approximately $24 million USD) over four and a half years to the project. The original EPIQ roadmap called for a pilot system of up to 30 qubits by end of 2024, followed by a full gate-based system of up to 60 qubits integrated into JSC's HPC infrastructure by 2026 — the milestone JION's inauguration now represents.eleQtron was founded in 2020 as a spin-out from the University of Siegen by Wunderlich (the MAGIC technique's inventor), Jan Henrik Leisse (CEO), and Michael Johanning (CTO). In May 2026, eleQtron closed a €57 million funding round (approximately $66 million USD) led by Schwarz Digits — the digital and IT arm of the Schwarz Group, Europe's largest retailer — with participation from the European Innovation Council Fund, Earlybird, Ankaa Ventures, Precitec, NRW.BANK, and IFB Innovationsstarter. The round ranked among the largest Series A deals in quantum computing globally, backed by an order backlog of more than €54 million (approximately $63 million USD). "Quantum computing is transitioning from a research-driven technology to an industrially usable infrastructure. With this funding, we are accelerating that transition and building systems that will solve real-world industrial problems," Leisse said at the Series A announcement.How Does JION's Approach Compare to Quantinuum, IonQ, and Others?The trapped-ion competitive landscape is more crowded than it was two years ago. On the fidelity dimension, eleQtron's documented MAGIC performance sits below the leading players. Quantinuum's H-series systems, which use laser-based control, were ranked first among 19 commercially available quantum processing units in an independent benchmarking study conducted by JSC, AIDAS, RWTH Aachen University, and Purdue University — the same Jülich facility now integrating JION. IonQ crossed the "four-nines" threshold (99.99% two-qubit gate fidelity) in October 2025 using its Electronic Qubit Control technology, derived from Oxford Ionics — a separate microwave-based approach that integrates qubit control onto standard semiconductor chips.Within the trapped-ion field, eleQtron competes not only on fidelity but on a different set of engineering bets: room-temperature trap operation, microwave-hardware compatibility with standard RF electronics, and a fabrication partnership with Infineon that targets series production. On the operating temperature question, the architecture is distinct from Quantinuum, which uses laser-based control and cryogenic staging for readout. On the scalability question, eleQtron's thesis is that microwave control will be easier to engineer at scale than laser optics — a hypothesis now being tested in a production environment at one of Europe's premier computing centers.Neutral-atom quantum computing platforms from companies such as QuEra and Pasqal have also entered the race, as have superconducting-qubit systems from IBM (which has published roadmaps toward thousands of physical qubits) and Google. The JION inauguration does not claim to resolve the question of which architecture will dominate practical quantum computing, a question that remains genuinely open. What it establishes is that the microwave trapped-ion approach can now be compared, on equal infrastructure, to other systems in the same JUNIQ facility.Is Quantum Advantage within Reach from JION?"Quantum advantage" — the demonstration that a quantum computer can solve a useful problem faster or more efficiently than any classical algorithm on the best classical hardware — remains contested and unachieved for practical workloads, regardless of platform. John Preskill, who coined the term "quantum supremacy," defined it in 2012 as computing a task "beyond the reach of classical computers," making no reference to usefulness. Dominik Hangleiter of the Simons Institute for the Theory of Computing at UC Berkeley found, polling audiences at recent physics research meetings, that fewer than half believed quantum advantage had been demonstrated — despite five-plus years of experiments designed to do exactly that.JION at 60 qubits, with Bell state fidelity around 99.7%, is not a fault-tolerant system and is not claiming to be one. JSC has positioned it as a near-term hybrid resource: a device that can run quantum subroutines for specific classes of chemistry, optimization, and machine learning problems, with its classical companion JUPITER handling the bulk computation. This is the architecture in which researchers believe near-term quantum value — if it appears — will most likely first materialize.What Comes Next: SQALING and Q-STAR.NRWThe September 3 ceremony also brought funding approval for two successor programs. SQALING (Scalable Quantum Computing from NRW) is an eleQtron-led development project receiving up to approximately €25 million (approximately $29 million USD) from NRW via EU structural funds, aimed at developing next-generation chip-based trapped-ion platforms with potential industrial deployment, with a production-ready quantum computer as a target by around 2027. Q-STAR.NRW aims to procure and integrate a semiconductor-based quantum computer targeting up to 200 qubits into JUNIQ, funded with up to approximately €25 million ($29 million USD) from EU structural funds for the Rhenish mining area under Germany's Investment Act for Coal Regions. Both projects are intended to reinforce Germany's quantum technology sovereignty and establish NRW as a sustained center for quantum innovation — a goal with roots in Germany's post-coal economic transition for the Rhenish region.Currency conversions are approximate, based on ECB reference rates as of early September 2026.Frequently Asked QuestionsWhat is MAGIC, and why does it matter for quantum computing?MAGIC stands for Magnetic Gradient Induced Coupling. It is a method of controlling trapped-ion qubits using microwave fields rather than lasers, developed by Prof. Christof Wunderlich at the University of Siegen. A static magnetic field gradient makes each ion in the trap resonant at a slightly different frequency, allowing microwaves to address individual qubits precisely. The main engineering advantage is that it replaces a complex optical alignment system with standard radio-frequency electronics, which are easier to miniaturize, consume roughly one-fifth the power of laser-based alternatives, and can in principle be integrated onto semiconductor chips — a potential path toward quantum processors that fit in data-center environments rather than laser laboratories. Research from the Wunderlich group has documented Bell state fidelities of approximately 99.7% using this approach.How does Germany's JION compare to the leading quantum computers from Quantinuum and IonQ?On the key metric of two-qubit gate fidelity, JION lags. Quantinuum's H-series systems and IonQ's Electronic Qubit Control technology both achieve above 99.9% two-qubit fidelity, with IonQ crossing 99.99% in October 2025. JION's MAGIC architecture has demonstrated Bell state fidelities of approximately 99.7%, a gap that is significant for fault-tolerant quantum computing, where higher fidelity reduces error-correction overhead. Where JION differentiates is integration strategy: it is the first gate-based trapped-ion quantum computer deployed as a production resource inside a major supercomputing facility — JUNIQ at Jülich — directly coupled to JUPITER, Europe's fastest supercomputer. This hybrid positioning is deliberate: JSC's bet is that near-term quantum value will come from coupling quantum processors to classical supercomputers, not from running quantum algorithms in isolation.Can a trapped-ion quantum computer really run at room temperature, and why does that matter?The ion trap in JION does operate at room temperature — and that distinguishes it sharply from superconducting qubit platforms such as IBM's and Google's, which require dilution refrigerators to cool their processors to approximately 15 millikelvin (−459.4°F), close to absolute zero. The ytterbium ions themselves are laser-cooled to very low temperatures for state preparation, but that is a localized, targeted process, not a system-wide cryogenic requirement. This matters because dilution refrigerators are expensive, physically large, and slow to cycle — they constrain the number of qubits that can practically be integrated into a system and make infrastructure costs difficult to scale. Room-temperature trap operation is one of the reasons eleQtron and its Infineon Technologies chip-fabrication partner believe trapped-ion systems using the MAGIC approach could eventually fit into standard data-center infrastructure. For a technical overview of the MAGIC microwave control method, the IoT Insider has published detailed documentation from eleQtron's hardware partners.What is hybrid quantum-classical computing, and how does JION fit into it?Hybrid quantum-classical computing is a paradigm in which quantum and classical processors work together on the same problem. The classical computer handles most of the computation, but offloads specific subroutines to the quantum processor — tasks such as evaluating quantum chemistry Hamiltonians, solving constrained optimization problems, or training certain classes of machine-learning models — where quantum approaches might provide a speedup. JION's integration into JUNIQ, alongside JUPITER's 24,000 GPUs, is designed precisely for this mode. Users can submit hybrid jobs through JSC's JuDoor access platform, with the quantum subroutine running on JION and the classical envelope running on JUPITER or JSC's other supercomputers. Most researchers believe hybrid computing is where near-term quantum value will first appear, because it lowers the bar for the quantum processor: it doesn't need to run a full algorithm fault-tolerantly, just the hardest subroutine, and it doesn't need to beat every classical approach — just the part it handles.
