Example job

A minimal Bell pair circuit, run on a quantum computer. Replace <CORTEX_URL> and <QUANTUM_COMPUTER_ID> with the values from Runtime identifiers on your device's page. <CORTEX_URL> is the name of an environment variable set by the fiqci-vtt-* module.

Get the backend

VLQ backend

The syntax for fetching the VLQ backend is different. See the VLQ page for instructions.

QiskitCirq

Load the module with module load fiqci-vtt-qiskit.

import os
from iqm.qiskit_iqm import IQMProvider

cortex_url = os.getenv("<CORTEX_URL>")
provider = IQMProvider(cortex_url, quantum_computer="<QUANTUM_COMPUTER_ID>")
backend = provider.get_backend()

Load the module with module load fiqci-vtt-cirq.

import os
from iqm.cirq_iqm.iqm_sampler import IQMSampler

cortex_url = os.getenv("<CORTEX_URL>")
sampler = IQMSampler(cortex_url, quantum_computer="<QUANTUM_COMPUTER_ID>")

Define and run your circuit

QiskitCirq

from qiskit import QuantumCircuit, QuantumRegister, transpile

shots = 1000

qreg = QuantumRegister(2, "QB")
circuit = QuantumCircuit(qreg, name="Bell pair circuit")
circuit.h(qreg[0])
circuit.cx(qreg[0], qreg[1])
circuit.measure_all()

transpiled_circuit = transpile(circuit, backend=backend)

job = backend.run(transpiled_circuit, shots=shots)
print("Job ID:", job.job_id())

print(job.result().get_counts())

import cirq

shots = 1000

qubits = cirq.NamedQubit.range(2, prefix="QB")
circuit = cirq.Circuit(
    cirq.H(qubits[0]),
    cirq.CNOT(qubits[0], qubits[1]),
    cirq.measure(*qubits, key="m"),
)

result = sampler.run(circuit, repetitions=shots)
print("Job ID:", result.metadata.job_id)

print(result.histogram(key="m"))

Save your Job ID!

There is currently no way to list previous job IDs, so always print your job ID after submission and save it somewhere. The same applies to the calibration set ID.
