IterativeScanningGateRemovalPass

class IterativeScanningGateRemovalPass(width_to_partition=5, block_size=3, *args, **kwargs)

Bases: PassAlias

The IterativeScanningGateRemovalPass class.

Starting from one side of the circuit, attempt to remove gates one-by-one. Repeat this until the circuit no longer changes. This will partition the circuit first if the circuit width is too large.

__init__(width_to_partition=5, block_size=3, *args, **kwargs)

Construct a IterativeScanningGateRemovalPass.

Parameters:

• width_to_partition (int) – Circuits at least as wide as this will be partitioned first.

• block_size (int) – If the circuit is partitioned, it will be partitioned into blocks of this width.

• *args (Any) – Arguments passed directly to ScanningGateRemovalPass.

• *kwargs (Any) – Keyword arguments passed directly to ScanningGateRemovalPass.

Raises:

• ValueError – If width_to_partition or block_size is nonpositive.

• ValueError – If width_to_partition is less than or equal to block_size.

Attributes

name	The name of the pass.
