Quantum computing arrangement and quantum computer

Abstract

In an embodiment a quantum computing arrangement includes a permanent magnet arrangement, a substrate, wherein the quantum computing arrangement is configured to realize a planar Paul trap configured for trapping at least one ion crystal having several ions lined up along a predefined line, and components, constituting electrodes of the planar Paul trap configured for producing an electrical trapping potential, arranged on a top side of the substrate, wherein the predefined line is located above the top side, wherein the permanent magnet arrangement is configured to establish a magnetic field with a magnitude of the magnetic field changing along the predefined line, wherein the permanent magnet arrangement comprises a plurality of permanently magnetized segments, wherein each segment has a magnetization direction, and wherein the segments are arranged in a Halbach arrangement.

Dependencies are inferred from the claim text.
