The classes :class:`~qiskit.circuit.Qubit`, :class:`.Clbit` and :class:`.AncillaQubit` now
|
|
have the ``__slots__`` attribute. This is to reduce their memory usage. As a
|
|
side effect, they can no longer have arbitrary data attached as attributes
|
|
to them. This is very unlikely to have any effect on downstream code other
|
|
than performance benefits.
