Source code for qarp.devices._architecture

"""Architecture helpers.

Returns a ``qx.Architecture`` describing device qubit connectivity.  Pass
the result to :class:`qarp.devices.Device` as the ``architecture`` argument.
The Engine consumes it via the qarpx-native router during ``build()`` —
``Sabre`` by default, ``Lite`` for the greedy shortest-path sweep.
