    shots=1000,
    base_url="https://davidjgrimsley.com/public-facing/api/quantum",
    api_key="your-runtime-api-key",
)

@qml.qnode(dev)

print(bell())

Configuration

Constructor keyword arguments:

• base_url: Quantum API base URL (with or without /v1)
• api_key: runtime X-API-Key for protected routes
• bearer_token: optional bearer token for advanced auth routing
• timeout: client timeout in seconds
• qasm_version: currently "auto", "2", or "3" (default "auto")
• seed: optional simulator seed forwarded to /v1/qasm/run
• client: optional preconfigured quantum_api_sdk.QuantumApiClient

Finite-shot QNodes are reconstructed from counts. Analytic QNodes (shots=None) use statevector post-processing.
