Component Library & Layout Viewer

This page describes how to explore the catalog of pre-designed quantum hardware components and inspect the final physical layout.

Component Library

The Component Library is a catalog of standard superconducting components.

  1. Go to the Component Library screen.

  2. Search and filter components by category: * Qubits: Dolan junctions, Manhattan junctions, SQUID loops, SNAILs, Transmon Crosses, and Transmon Pockets. * Feedlines: Microwave pathways for reading multiple qubits. * Resonators: Standard Route Meanders and Rectangular Resonator Coils. * Couplers: Direct or bus couplers linking qubits. * Routes: Automated transmission line pathways. * Launchpads: Signal launches for external cabling.

  3. Click on a component card to view its description, pin configuration, parameter fields (such as default dimensions), and GDS layer mapping.

What this means: The library serves as an encyclopedia of all standard hardware primitives that are compatible with the schematic editor and Qiskit Metal.

Layout Viewer

The Layout Viewer allows you to inspect the physical GDS layout file that will be sent to the fabrication facility.

  1. Navigate to the Layout Viewer page.

  2. The screen displays a high-resolution, multi-layer rendering of the chip.

  3. Use the control panel to inspect individual mask layers: * Layer 1 (Metalization): Ground planes, transmission lines, and qubit capacitor pads. * Layer 2 (Josephson Junctions): The superconducting junctions. * Layer 3 (Dielectric Vias): Contact holes and insulation windows.

  4. Pan, zoom, and measure features on the chip canvas to verify spacing.

What you just did: You inspected the raw geometrical definitions of the chip (which dictates how the physical layout will be patterned onto the silicon wafer).
