PrePropagate¶

class samplomatic.pre_samplex.PrePropagate(subsystems: Partition[int], direction: Direction, operation: Gate, partition: Partition[int], spec: InstructionSpec)[source]¶

Bases: PreNode

The propagation node type used during samplex building.

Attributes Summary

`direction`	The direction of virtual gates that cat interact with this node.
`operation`	The operation to propagate through.
`partition`	A partition of subsystem indices, each of which is propagated jointly.
`spec`	Specification for how the operation acts on virtual gates.
`subsystems`	The subsystems that virtual gates act on.

Methods Summary

get_style()

Summarizes the style of this node when plotted via plot_graph().

Attributes Documentation

direction: Direction = <dataclasses._MISSING_TYPE object>¶: The direction of virtual gates that cat interact with this node.

operation: Gate = <dataclasses._MISSING_TYPE object>¶: The operation to propagate through.

partition: Partition[int] = <dataclasses._MISSING_TYPE object>¶

A partition of subsystem indices, each of which is propagated jointly.

For example, a CX gate propagates pairs of single-qubit subsystems jointly. In this case, a partition would be a list of pairs of subsystem indices, where pairs are disjoint from each other.

spec: InstructionSpec = <dataclasses._MISSING_TYPE object>¶: Specification for how the operation acts on virtual gates.

subsystems: Partition[int] = <dataclasses._MISSING_TYPE object>¶: The subsystems that virtual gates act on.
