features_transpiler:

|
|
The :class:`.SabreLayout` transpiler pass has been updated to run an
|
|
additional 2 or 3 layout trials by default independently of the
|
|
``layout_trials`` keyword argument's value. A trivial
|
|
layout and its reverse are included for all backends, just like the :class:`.DenseLayout`
|
|
trial that was added in 1.2.0. In addition to this, the largest rings on
|
|
an IBM backend heavy hex connectivity graph are added if the backends are 127,
|
|
133, or 156 qubits. This can provide a good starting point for some circuits on these commonly run
|
|
backends, while for all others it's just an additional "random trial".
