For example, equality of two programs are efficiently checked on DAG representation. .. code-block:: python from qiskit import pulse my_gaussian0 = pulse.Gaussian(100, 0.5, 20) my_gaussian1 = pulse.Gaussian(100, 0.3, 10) with pulse.build() as sched1: with pulse.align_left(): pulse.play(my_gaussian0, pulse.DriveChannel(0)) pulse.shift_phase(1.57, pulse.DriveChannel(2)) pulse.play(my_gaussian1, pulse.DriveChannel(1)) with pulse.build() as sched2: with pulse.align_left(): pulse.shift_phase(1.57, pulse.DriveChannel(2)) pulse.play(my_gaussian1, pulse.DriveChannel(1)) pulse.play(my_gaussian0, pulse.DriveChannel(0)) Here the ``sched1 `` and ``sched2`` are different implementations of the same program, but it is difficult to confirm on the list representation. Another example is instruction optimization. .. code-block:: python from qiskit import pulse with pulse.build() as sched: with pulse.align_left(): pulse.shift_phase(1.57, pulse.DriveChannel(1)) pulse.play(my_gaussian0, pulse.DriveChannel(0)) pulse.shift_phase(-1.57, pulse.DriveChannel(1)) In above program two ``shift_phase`` instructions can be cancelled out because they are consecutive on the same drive channel. This can be easily found on the DAG representation. Args: block ("ScheduleBlock"): A schedule block to be converted. Returns: Instructions in DAG representation. Raises: PulseError: When the context is invalid subclass. )alignment_context is_sequential_sequential_allocation_parallel_allocation)rs Q/granary/edev/quantum/lib/python3.11/site-packages/qiskit/pulse/transforms/dag.py block_to_dagrs/j ,-%e,,,  & &&ctj}g}d}|jD]H}||}|dkr|||f|}I|||S)zDA helper function to create a DAG of a sequential alignment context.N)rxPyDAGblocksadd_node num_nodesappendadd_edges_from_no_data)rdagedgesprev_idelmnode_ids rr r Us (**C#%EG|,,s## ==??Q   LL'7+ , , ,u%%% Jrctj}i}t}d}|jD]}||} |jD]6}|||}||||f|||<7W#t$rM| D]!\}}|||f|||<"|}YwxYw| t||S)zBA helper function to create a DAG of a parallel alignment context.N) rrsetrrchannelspopaddrcopyitemsrlist) rrslotsrprev_referencerrchanrs rrrds( (**C "E"%%%EN| % %,,s## %  & &))D.99&IIw0111%d  & ( % % %!&!3!3!5!5 & & g 7G,---%d $NNN  % tE{{+++ Js>BACC)rrrr )rr )__doc__ __future__rtyping rustworkxrqiskit.pulse.channelsrqiskit.pulse.exceptionsr TYPE_CHECKING qiskit.pulserrr rrrr4sPO"""""" *)))))<<<<<< +******7'7'7'7't    r
