Forschungszentrum Jülich Operates eleQtron’s JION Trapped-Ion QPU via JUNIQ Infrastructure

Research center Forschungszentrum Jülich and University of Siegen spin-off eleQtron GmbH have officially brought the JION (Jülich trapped-ION) quantum computer into operation at the Jülich Supercomputing Centre (JSC). Integrated into the JUNIQ (Jülich UNified Infrastructure for Quantum computing) platform, the gate-based trapped-ion processor is linked directly to JSC’s High-Performance Computing (HPC) supercomputing cluster—including the JUPITER exascale system—to enable hybrid quantum-classical workloads across transport optimization, materials science, and chemical simulation.

MAGIC Microwave Control and Room-Temperature Qubit Trapping

Unlike conventional trapped-ion architectures that rely on complex, multi-laser optical setups for individual qubit addressing, JION employs eleQtron’s proprietary MAGIC (Magnetic Gradient Induced Coupling) technology:

• Microwave Control Fields: Replaces individual laser beams with static magnetic field gradients and globally applied microwave pulses, allowing precise single-qubit addressing and multi-qubit gate operations through radio-frequency (RF) signals.
• Reduced Thermal Constraints: Operating trapped Ytterbium ions inside electromagnetic fields eliminates the need for dilution refrigerators required by superconducting QPUs, allowing the core trap assembly to operate at room temperature.
• All-to-All Qubit Connectivity: Long-range magnetic gradient coupling enables direct gate operations between non-adjacent ions within the trap array, minimizing compiler SWAP gate overhead during circuit synthesis.
