IBM Quantum Python API Docs | dltHub

Build a IBM Quantum-to-database pipeline in Python using dlt with AI harness support for Claude Code, Cursor, and Codex.

Last updated:

IBM Quantum Services provides a REST API to access quantum processors, submit jobs, and manage sessions. The REST API base URL is https://quantum.cloud.ibm.com/api/v1 and requests require a Bearer token in the Authorization header and a CRN in the Service-CRN header.

dlt is an open-source Python library that handles authentication, pagination, and schema evolution automatically. dlthub provides AI context files that enable code assistants to generate production-ready pipelines. Install with uv add "dlt[hub]" and start loading IBM Quantum data in under 10 minutes.


What data can I load from IBM Quantum?

Here are some of the endpoints you can load from IBM Quantum:

ResourceEndpointMethodData selectorDescription
jobs/v1/jobsGETjobsList quantum program jobs
job_details/v1/jobs/{id}GETGet details for a specific job
backends/backendsGETList quantum backends
backend_properties/backends/{id}/propertiesGETGet properties for a specific backend
tags/tagsGETList available job tags

How do I authenticate with the IBM Quantum API?

Authentication requires an IBM Cloud IAM bearer token, generated by exchanging an API key via the IAM Identity Services API. Requests must include the 'Authorization: Bearer ' and 'Service-CRN: ' headers, along with an 'IBM-API-Version' header.

1. Get your credentials

To obtain your credentials, navigate to the IBM Quantum Platform dashboard. Under your account settings or the dashboard home, locate the section for API keys to create a new 44-character API key. Copy this key immediately, as it will not be visible again. If necessary, also locate your Instance CRN from the Instances page in the dashboard menu. Use the API key to generate a short-lived IAM bearer token via a POST request to the IBM Cloud IAM Identity Services API before calling other REST API endpoints.

2. Add them to .dlt/secrets.toml

[sources.ibm_quantum_source] ibm_quantum_api_key = "your_44_character_api_key_here" ibm_quantum_service_crn = "your_instance_crn_here"

dlt reads this automatically at runtime — never hardcode tokens in your pipeline script. For production environments, see setting up credentials with dlt for environment variable and vault-based options.


How do I set up and run the pipeline?

Set up a virtual environment and install dlt:

uv init uv add "dlt[hub]"

1. Install the dlt AI harness:

uv run dlthub ai init --agent <your-agent> # <agent>: claude | cursor | codex

This installs project rules, a secrets management skill, appropriate ignore files, and configures the dlt MCP server for your agent. Learn more →

2. Install the rest-api-pipeline toolkit:

uv run dlthub ai toolkit install rest-api-pipeline

This loads the skills and context about dlt the agent uses to build the pipeline iteratively, efficiently, and safely. The agent uses MCP tools to inspect credentials — it never needs to read your secrets.toml directly. Learn more →

3. Start LLM-assisted coding:

Use /find-source to load data from the IBM Quantum API into DuckDB.

The rest-api-pipeline toolkit takes over from here — it reads relevant API documentation, presents you with options for which endpoints to load, and follows a structured workflow to scaffold, debug, and validate the pipeline step by step.

4. Run the pipeline:

uv run python ibm_quantum_pipeline.py

If everything is configured correctly, you'll see output like this:

Pipeline ibm_quantum_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset ibm_quantum_data The duckdb destination used duckdb:/ibm_quantum.duckdb location to store data Load package 1749667187.541553 is LOADED and contains no failed jobs

Inspect your pipeline and data:

uv run dlthub show

This opens the Pipeline Dashboard where you can verify pipeline state, load metrics, schema (tables, columns, types), and query the loaded data directly.


Python pipeline example

This example loads usage and backends from the IBM Quantum API into DuckDB. It mirrors the endpoint and data selector configuration from the table above:

import dlt from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources @dlt.source def ibm_quantum_source(api_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://quantum.cloud.ibm.com/api/v1", "auth": {"type": "bearer", "token": api_key}, }, "resources": [ {"name": "jobs", "endpoint": {"path": "v1/jobs", "data_selector": "jobs"}}, {"name": "backends", "endpoint": {"path": "backends"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="ibm_quantum_pipeline", destination="duckdb", dataset_name="ibm_quantum_data", ) load_info = pipeline.run(ibm_quantum_source()) print(load_info)

To add more endpoints, append entries from the resource table to the "resources" list using the same name, path, and data_selector pattern.


How do I query the loaded data?

Once the pipeline runs, dlt creates one table per resource. You can query with Python or SQL.

Python (pandas DataFrame):

import dlt data = dlt.pipeline("ibm_quantum_pipeline").dataset() sessions_df = data.jobs.df() print(sessions_df.head())

SQL (DuckDB example):

SELECT * FROM ibm_quantum_data.jobs LIMIT 10;

In a marimo or Jupyter notebook:

import dlt data = dlt.pipeline("ibm_quantum_pipeline").dataset() data.jobs.df().head()

See how to explore your data in marimo Notebooks and how to query your data in Python with dataset.


What destinations can I load IBM Quantum data to?

dlt supports loading into any of these destinations — only the destination parameter changes:

DestinationExample value
DuckDB (local, default)"duckdb"
PostgreSQL"postgres"
BigQuery"bigquery"
Snowflake"snowflake"
Redshift"redshift"
Databricks"databricks"
Filesystem (S3, GCS, Azure)"filesystem"

Change the destination in dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. See the full destinations list.
