Quantum Resource Management Interface(QRMI)

QRMI: Quantum Resource Management Interface

[!IMPORTANT] New Deprecations(Since 0.13.0)

The IBM Direct Access API has been renamed to the IBM Quantum System API.

As part of this change, the resource names and the prefixes of environment variables used by QRMI have been updated accordingly.

Items	Deprecated names	New names
Resource type text	direct-access	ibm-quantum-system
Resource type(C)	QRMI_RESOURCE_TYPE_IBM_DIRECT_ACCESS	QRMI_RESOURCE_TYPE_IBM_QUANTUM_SYSTEM
Resource type(Python)	ResourceType.IBMDirectAccess	ResourceType.IBMQuantumSystem
Resource type(Rust)	ResourceType::IBMDirectAccess	ResourceType::IBMQuantumSystem
QuantumResource trait implementator(Rust)	qrmi::ibm::IBMDirectAccess	qrmi::ibm::IBMQuantumSystem
Environment variable prefixes	QRMI_IBM_DA_	QRMI_IBM_QS_

A transition period will be in effect until July 2, 2026. During this period, both the legacy and the new resource names and environment variable prefixes are supported to ensure backward compatibility. After the transition period ends, support for the legacy names will be removed, and users are expected to migrate fully to the new naming scheme.

This is repository with Quantum Resource Management Interface (QRMI) implementation.

QRMI ⚛️ is a vendor agnostic library to control state, run tasks and monitor behavior of quantum computational resources (qubits, QPUs, entire quantum systems, etc.).

QRMI acts like a thin middleware layer that abstracts away complexities of controling quantum resources by exposing set of simple APIs to acquire/release hardware, run tasks and monitor state of quantum resources.

QRMI is written in Rust 🦀 with Python 🐍 and C ©️ APIs exposed for ease of integration to pretty much any computational envrionment.

Examples

All full examples are available in examples folder.

C

This example demonstrates QRMI using the Quantum System API for IBM Quantum machines.

#include "qrmi.h"

int main(int argc, char *argv[]) {
    ...

    QrmiQuantumResource *qrmi = qrmi_resource_new(argv[1], QRMI_RESOURCE_TYPE_IBM_QUANTUM_SYSTEM);
    ...

    QrmiReturnCode rc = qrmi_resource_metadata(qrmi, &metadata);
    ...

    QrmiResourceMetadata *metadata = NULL;
    rc = qrmi_resource_acquire(qrmi, &acquisition_token);
    ...

    QrmiPayload payload;
    payload.tag = QRMI_PAYLOAD_QISKIT_PRIMITIVE;
    payload.QISKIT_PRIMITIVE.input = (char *)input;
    payload.QISKIT_PRIMITIVE.program_id = argv[3];
    ...

    char *job_id = NULL;
    rc = qrmi_resource_task_start(qrmi, &payload, &job_id);
    ...

    QrmiTaskStatus status;
    rc = qrmi_resource_task_status(qrmi, job_id, &status);
    ...

    qrmi_resource_task_stop(qrmi, job_id);
    qrmi_string_free(job_id);
    qrmi_resource_free(qrmi);

    return EXIT_SUCCESS;

error:
    qrmi_resource_free(qrmi);
    return EXIT_FAILURE;
}

See example of QRMI C working with IBM Qiskit Runtime Service or Pasqal Cloud.

All examples for QRMI C are available in this folder.

Python

This example demonstrates QRMI using the Quantum System API for IBM Quantum machines.

from qrmi import QuantumResource, ResourceType, Payload, TaskStatus

# create resource handler
qrmi = QuantumResource("ibm_rensselaer", ResourceType.IBMQuantumSystem)

# acquire resource
lock = qrmi.acquire()

# run task
payload = Payload.QiskitPrimitive(input=primitive_input, program_id=args.program_id)
job_id = qrmi.task_start(payload)

print(qrmi.task_result(job_id).value)

qrmi.task_stop(job_id)

# release resource
qrmi.release(lock)

Full example is available here.

Python QRMI can be used to implement Qiskit primitives (Sampler and Estimator). See example of Qiskit primitives here for IBM backends or for Pasqal machines.

See example of QRMI working with Pasqal Pulser.

Pasqal Cloud Examples

QRMI Pasqal Cloud supports both Qiskit, Pulser and CUDA-Q analog programs.

See the Pasqal Cloud examples in this repository:

• Python: examples/qrmi/python/pasqal_cloud
• Rust: examples/qrmi/rust/pasqal_cloud
• C: examples/qrmi/c/pasqal_cloud
• CUDA-Q examples/qrmi/python/cudaq

Rust

This example demonstrates QRMI using the Quantum System API for IBM Quantum machines.

use qrmi::{ibm::IBMQuantumSystem, models::Payload, models::TaskStatus, QuantumResource};
...

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    ...
    let mut qrmi = IBMQuantumSystem::new(&args.backend);

    let lock = qrmi.acquire().await?;
    ...

    let target = qrmi.target().await;
    ...

    let payload = Payload::QiskitPrimitive {
        input: contents,
        program_id: args.program_id,
    };

    let job_id = qrmi.task_start(payload).await?;
    println!("Job ID: {}", job_id);
    let one_sec = time::Duration::from_millis(1000);
    loop {
        let status = qrmi.task_status(&job_id).await?;
        println!("{:?}", status);
        if matches!(status, TaskStatus::Completed) {
            println!("{}", qrmi.task_result(&job_id).await?.value);
            break;
        } else if matches!(status, TaskStatus::Failed | TaskStatus::Cancelled) {
            break;
        }
        thread::sleep(one_sec);
    }
    let _ = qrmi.task_stop(&job_id).await;

    let _ = qrmi.release(&lock).await;
    Ok(())
}

QRMI usage in Slurm plugin for quantum resources

One of example of usage of QRMI in compute infrastrcture project is Slurm plugin for quantum resources. QRMI is used in Slurm plugin to control quantum resources during lifetime of Slurm job.

See implementation and documentation of Slurm plugin for quantum resources here.

Pre-commit detect-secrets

detect-secrets is an open-source, developer-friendly tool designed to scan codebases for mistakenly committed secrets—such as API keys, passwords, and private tokens—before they leak. To keep our credentials secure, we recommend that all developers integrate this into their workflow using the following instructions.

• Prerequisites: Before you begin, ensure you have a Python virtual environment (venv) active. You will need to install pre-commit, which manages the hooks that run detect-secrets automatically.

pip install pre-commit
pre-commit install

Please find .pre-commit-config.yaml for the initial setup.
Following command was used to generate .secrets.baseline and to maximize the detection coverage.

detect-secrets scan --force-use-all-plugins > .secrets.baseline

Handling False Positives
If the pre-commit hook identifies a secret that you have verified is not sensitive (a false positive), please use the following command to audit and update the baseline file. Once updated, include the modified .secrets.baseline in your Pull Request to ensure the pre-commit passes in the future.

pip install detect-secrets
detect-secrets scan --baseline .secrets.baseline
detect-secrets audit .secrets.baseline

Manual Execution and Overrides
To manually trigger a scan of all files in the repository for a local sanity check, execute the following command:

pre-commit run --all-files

Bypassing the Hook (Not Recommended)
While not recommended, if you must force a commit without running the pre-commit checks (e.g., during an emergency fix), you may use the --no-verify flag:

git commit -m "Your message" --no-verify
