 Here the default compilation pass is applied by :py:meth:`IBMQBackend.get_compiled_circuit`. See `this page <https://cqcl.github.io/pytket-qiskit/api/index.html#default-compilation>`_ for more details.
 
 As an alternative, We can experiment with constructing our own circuit compilation routines in pytket. Passes from the :py:mod:`pytket.passes` module can be applied individually or composed in sequence.
