Estimate job run time

After submitting a job to the IBM Quantum channel, you can see an estimation for how much quantum time the job will take to run by using job.usage_estimation. Alternatively, you can view this information on the IBM Quantum Platform user interface.

Quantum time is the duration, in seconds, a quantum system is committed to fulfilling a user request.

  • This only applies to jobs that use primitives.
  • This is not yet available on the IBM Qiskit Runtime on Cloud channel.


from qiskit import QuantumCircuit
from qiskit_ibm_runtime import QiskitRuntimeService, Sampler
service = QiskitRuntimeService()
# Create a new circuit with two qubits (first argument) and two classical
# bits (second argument)
qc = QuantumCircuit(2, 2)
# Add a Hadamard gate to qubit 0
# Perform a controlled-X gate on qubit 1, controlled by qubit 0, 1)
# Measure qubit 0 to cbit 0, and qubit 1 to cbit 1
qc.measure(0, 0)
qc.measure(1, 1)
# Run on the least-busy backend you have access to
backend = service.least_busy(simulator=False,operational=True)
# Create a Sampler object
sampler = Sampler(backend)
# Submit the circuit to the sampler
