▎ 摘　　要

NOVELTY - The system (100) has an angstrom confinement assembly which is positioned in a microchannel between two reservoirs. The assembly has a set of spacers defining angstrom conduits, where water molecules and ionic compounds are received in reservoirs. Two electrodes are positioned in or adjacent to the microchannel proximate to the reservoirs, respectively. The electrodes receive an electric field such that positive ions of the compounds are separated from negative ions by inducing the positive ions to flow through the conduits when the electric field is applied, and water molecules flow into conduits due to capillary forces. The first and second component comprises substrates comprised of silicon dioxide coated silicon or silicon nitride coated silicon. The spacers are comprised of hexagonal boron nitride (hBN) and/or graphene. The ionic compounds are cesium chloride or sodium chloride. USE - System for angstrom confinement of trapped ion e.g. superconducting loop, spin-based quantum dot, topological qubit, coupled quantum wire, diamond vacancy and metallic-like carbon nanosphere. ADVANTAGE - The angstrom confinement of trapped ions can be performed efficiently. The scalability of harnessing many such trapped ions is improved. The need for large-scale expensive instruments and multiple laser systems can be avoided. The size and cost of the system can be reduced. The performance of the quantum computer can be improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for angstrom confinement of trapped ions. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a system for angstrom confinement of trapped ions.
