merge_parallel_block_layers#

tqec.compile.blocks.merge_parallel_block_layers(blocks_in_parallel, scalable_qubit_shape)[source]#

Merge several stacks of layers executed in parallel into one stack of larger layers.

Parameters:

  • blocks_in_parallel (Mapping[LayoutPosition2D, Block]) – a 2-dimensional arrangement of blocks. Each of the provided block MUST have the exact same duration (also called “temporal footprint”, or number of atomic layers).

  • scalable_qubit_shape (PhysicalQubitScalable2D) – scalable shape of a scalable qubit. Considered valid across the whole domain.

Returns:

a stack of layers representing the same slice of computation as the provided blocks_in_parallel.

Raises:

  • TQECException – if two items from the provided blocks_in_parallel do not have the same temporal footprint.

  • NotImplementedError – if the provided blocks cannot be merged due to a code branch not being implemented yet (and not due to a logical error making the blocks unmergeable).

Return type:

list[LayoutLayer | BaseComposedLayer]
