The methods :meth:`.Pauli.evolve` and :meth:`.PauliList.evolve`
|
|
now have a new keyword argument, ``frame``, which is used to
|
|
perform an evolution of a Pauli by a Clifford. If ``frame='h'`` (default)
|
|
then it does the Heisenberg picture evolution of a Pauli by a Clifford
|
|
(:math:`P' = C^\dagger P C`), and if ``frame='s'`` then it does the
|
|
Schrödinger picture evolution of a Pauli by a Clifford
|
|
(:math:`P' = C P C^\dagger`). The latter option yields a faster calculation,
|
|
and is also useful in certain cases. This new option makes the calculation
|
|
of the greedy Clifford decomposition method in :class:`.decompose_clifford`
|
|
significantly faster.
