Summary

Story summary

Researchers from Lawrence Livermore National Laboratory and UC campuses 3D-printed a millimetre-scale quadrupole ion trap that confines calcium ions with competitive trap frequencies and error rates.
They achieved a two-qubit entangling gate with 98% fidelity.
Fabrication is rapid: 14 hours for a trap, 30 minutes for electrodes.
The work expands the design space and blends theory with experimental validation.
