The Sabre family of transpiler passes (namely :class:`.SabreLayout`
|
|
and :class:`.SabreSwap`) are now used by default for all circuits
|
|
when invoking the transpiler at optimization level 1 (e.g. calling
|
|
:func:`.transpile` or :func:`.generate_preset_pass_manager` with
|
|
keyword argument ``optimization_level=1``). Previously, circuits
|
|
with control flow operations used :class:`.DenseLayout` and
|
|
:class:`.StochasticSwap` with this profile.
