Assignments and modifications to the ``data`` attribute of
|
|
``qiskit.QuantumCircuit`` objects are now validated following the same
|
|
rules used throughout the ``QuantumCircuit`` API. This was done to
|
|
improve the performance of the circuits API since we can now assume the
|
|
``data`` attribute is in a known format. If you were manually modifying
|
|
the ``data`` attribute of a circuit object before this may no longer work
|
|
if your modifications resulted in an data structure other than the list
|
|
of instructions with context in the format ``[(instruction, qargs, cargs)]``
