A new kwarg, ``format_marginal`` has been added to the function
|
|
:func:`~qiskit.result.utils.marginal_counts` which when set to ``True``
|
|
formats the counts output according to the
|
|
:attr:`~qiskit.circuit.QuantumCircuit.cregs` in the circuit and missing
|
|
indices are represented with a ``_``. For example:
|
|
|
|
.. jupyter-execute::
|
|
|
|
from qiskit import QuantumCircuit, execute, BasicAer, result
|
|
from qiskit.result.utils import marginal_counts
|
|
qc = QuantumCircuit(5, 5)
|
|
qc.x(0)
|
|
qc.measure(0, 0)
|
|
|
|
result = execute(qc, BasicAer.get_backend('qasm_simulator')).result()
|
|
print(marginal_counts(result.get_counts(), [0, 2, 4], format_marginal=True))
|
|

An issue when passing the :class:`~qiskit.result.Counts` object
|
|
returned by :meth:`~qiskit.result.Result.get_counts` to
|
|
:func:`~qiskit.result.marginal_counts` would produce an improperly
|
|
formatted :class:`~qiskit.result.Counts` object with certain inputs has
|
|
been fixed. Fixes
