3D-Printed Micro Ion Trap Technology Applied to Quantum Information Applications

Researchers report a 3D printing approach using two-photon polymerization to build miniaturized, high-performance ion traps for quantum information processing. They merge benefits of 3D traps with on-chip miniaturization, deliver strong radial confinement, and support high-quality Rabi oscillations and two-qubit gates. This technique broadens design freedom, enabling optimized ion-trap geometries while preserving scalability and precision.
