LLNL and its research partners have created miniature ion traps with submicron precision and complex geometries made using 3D printing for fast, high-fidelity and scalable quantum computations. A patent is pending on the technology, with claims covering embodiments for a vertical ion trap, horizontal ion traps and methods of forming the ion traps using advanced manufacturing techniques.

LLNL has developed a method of extending device lifetimes by imprinting into the device a shape that excludes specific vibrational modes, otherwise known as a phononic bandgap. Eliminating these modes prevents one of the primary energy loss pathways in these devices. LLNL’s new method enhances the coherence of superconducting circuits by introducing a phononic bandgap around the system’s…

The novel LLNL technique uses electric fields to drive and control assembly. In the literature such methods have heretofore only formed disordered ensembles. This innovative method increases local nanocrystal concentration, initiating nucleation and growth into ordered superlattices. Nanocrystals remain solvated and mobile throughout the process, allowing fast fabrication of ordered…
