Quantum Computing for All

Quantum hardware without the overhead. Run on QPUs from IonQ, Rigetti, IQM, and AQT through a single API — at half the cost of going direct. Free to start.

Get started free Visit openquantum.com

Start free with $50 of quantum compute, claimable every 90 days.

One API. Every Provider. Half the Cost.

Open Quantum connects you to leading quantum computers through a single unified API — no vendor accounts, no complex setup. The same circuits you build and simulate in Quantum Rings run on real hardware, unchanged.

Why Open Quantum

Real Hardware, Made Accessible

Free to Start

$50 of quantum compute, claimable every 90 days from your dashboard. No credit card needed.

One Unified API

Reach leading providers through a single API — no separate vendor accounts to manage.

Seamless Integration

Pip install into your existing quantum framework — Qiskit, PennyLane, or qBraid.

Running in Minutes

No vendor accounts, no complex setup. You can be on real hardware in minutes.

Works With Your Framework

Pip install and keep the tools you already use.

Try it

Real QPUs, One pip install Away

Drop Open Quantum into your PennyLane or Qiskit workflow with a plugin — swap the device, keep your circuit.

bash

pip install openquantum-sdk-pennylane

python

import os
import pennylane as qml

# Point PennyLane at a real QPU through Open Quantum
dev = qml.device(
    "openquantum.device",
    wires=2,
    shots=1024,
    backend="provider:QPU",   # e.g. "ionq:forte-1"
    client_id=os.environ["OPENQUANTUM_CLIENT_ID"],
    client_secret=os.environ["OPENQUANTUM_CLIENT_SECRET"],
)

@qml.qnode(dev)
def bell():
    qml.Hadamard(wires=0)
    qml.CNOT(wires=[0, 1])
    return qml.probs(wires=[0, 1])

print(bell())

Or, send QASM from anything

Have a circuit in any framework? Submit its OpenQASM with the core SDK.

bash

pip install openquantum-sdk

python

from openquantum_sdk.auth import ClientCredentials, ClientCredentialsAuth
from openquantum_sdk.clients import SchedulerClient, JobSubmissionConfig

scheduler = SchedulerClient(
    auth=ClientCredentialsAuth(ClientCredentials(client_id, client_secret)),
)

# Submit any circuit as OpenQASM
job = scheduler.submit_job(
    JobSubmissionConfig(backend_class_id="ionq:forte-1", shots=1024),
    file_path="bell_state.qasm",
)
print(job.id)
