QCLang Output Targets¶

Output Targets

QCLang currently produces one primary output format: validated JSON. This JSON is structured to be directly usable with Qiskit Metal and the Qubit-Pro frontend. Future targets are planned as the project expands.

json_ir (primary output)¶

The default output of ```` parse_prompt() ```` . A structured JSON string containing: chip metadata, qubits (TransmonCross), resonators (RouteMeander), and couplers (RoutePath). This is the JSON intermediate representation used by the Qubit-Pro frontend and backend APIs.

qiskit_metal¶

The component types in the JSON ( ```` TransmonCross ```` , ```` RouteMeander ```` ,: ```` RoutePath ```` ) map directly to Qiskit Metal component classes. The geometry

parameters (cross_width, trace_width, fillet, etc.) are Qiskit Metal parameters. The JSON can be consumed to programmatically instantiate Qiskit Metal designs.

Qubit-Pro API¶

The parser is exposed through backend API endpoints ( ```` /api/qclang/parse ```` ,: ```` /api/qclang/compile ```` ). The frontend editor submits prompts to these

endpoints and receives JSON to display in the visual designer.

Future targets¶

HFSS geometry export, Q3D netlist, SPICE-style circuit representation, and GDS layout: are planned for future releases as the synthesis pipeline matures.
