Multi-layer ion trap on shaped glass or dielectric substrate

An ion trap, comprising:

• a substrate made of a glass material or a dielectric material;
• and
• a stack of multiple layers disposed over the substrate and including at least one metal layer for routing, at least one dielectric layer, and at least one metal layer for top electrodes,
• wherein the substrate and the stack of multiple layers are shaped to form a hole that extends through the substrate and through the stack of multiple layers.

A quantum information processing system, comprising:

• an ion trap, the ion trap comprising:
• a substrate made of a glass material or a dielectric material, and
• a stack of multiple layers disposed over the substrate and including at least one metal layer for routing, at least one dielectric layer, and at least one metal layer for top electrodes,
• wherein the substrate and the stack of multiple layers are shaped to form a hole that extends through the substrate and through the stack of multiple layers;
• and
• a source configured to provide, from a back surface of the ion trap, atomic species that pass through the hole in the substrate and the stack of multiple layers of the ion trap to a top surface of the ion trap.
