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.

The approach is to use peroxides to modify the reaction kinetics in the production of polysiloxanes.  A radical initiator in the presence of a hydride-terminated polysiloxane will increase the rate of curing and reduce manufacturing costs.  At a minimum a formulation would contain a hydride-terminated polysiloxane, a platinum catalyst, and an initiator that generates radicals. …

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…
