Quantum Computing Asked by MShakeG on September 26, 2020
How can the CNOT
gate error between 2 qubits as shown on visual qubit coupling map on the IBMQ Dashboard be retrieved in Qiskit using the BackendProperties.gate_error method ?
I have been able to retrieve the U2
error rates as follows:
properties = backend.properties()
properties.gate_error('u2', 0) # u2 error rate for qubit-0
You can type the following:
provider = IBMQ.get_provider(hub='YOUR-HUB-NAME', group='YOUR-GROUP-NAME', project='YOUR-PROJECT_NAME')
provider.backends.backend
You should see an interactive widget with 5 tabs. Under the Multi-Qubit Gates tab, you can see the CNOT error rate between any two connected qubits on that given backend.
If you don't see the widget, import qiskit.tools.jupyter and then try to run the commands again.

Try this:
provider = IBMQ.get_provider(hub='YOUR-HUB-NAME', group='YOUR-GROUP-NAME', project='YOUR-PROJECT_NAME')
backend = provider.get_backend('ibmq_**your_device**')
for gate_i in hardware_backend.properties().gates:
print("{} gate on qubits {} error rate is {}{}".format(gate_i.name, gate_i.qubits, gate_i.parameters[0].value, gate_i.parameters[0].unit))
It should print out the list that you got from the Widget.
