QRMI Provider Example in C

GitHub

---

A unified example that works with any supported provider type (ibm-quantum-compute-service, ibm-quantum-system, etc.). The resource type is read from qrmi_config.json — no code changes needed when switching between providers.

Prerequisites

• C compiler/linker, cmake and make

• Build the QRMI Rust library

Config file

Create a qrmi_config.json with an is_dynamic: true entry:

qrmi_config.json

{
    "resources": [
        {
            "name": "ibm_inst1",
            "type": "ibm-quantum-compute-service",
            "is_dynamic": true,
            "environment": {
                "QRMI_IBM_QRS_ENDPOINT":     "https://quantum.cloud.ibm.com/api/v1",
                "QRMI_IBM_QRS_IAM_ENDPOINT": "https://iam.cloud.ibm.com",
                "QRMI_IBM_QRS_IAM_APIKEY":   "<your_api_key>",
                "QRMI_IBM_QRS_SERVICE_CRN":  "<your_service_crn>"
            }
        }
    ]
}

How to build this example

mkdir build

cmake ..
make

How to run this example

# No filter
./build/providers /path/to/qrmi_config.json ibm_inst1

# With filter
./build/providers /path/to/qrmi_config.json ibm_inst1 "num_qubits=127&name=ibm_*"
