app.processing.graph

Basic program graph used withing the app.processing.

Module Contents

class app.processing.graph.ProgramNode(name: str, label: str | None = None, is_ancilla_node: bool = False, id: uuid.UUID | None = None)

Represents a node in a visual model of an openqasm3 program.

Parameters:

  • name (str) – The id given from the front-end.

  • id (uuid.UUID | None) – Unique ID of this node, used in the renaming.

  • label (str | None) – (Optional) Label given from the front-end.

  • is_ancilla_node (bool) – This node is ancilla node in the model.

class app.processing.graph.IOConnection

Map output-reg from source to target input-reg with specified size.

class app.processing.graph.AncillaConnection

Map output qubits from source to target input qubits.

The qubits are identified via the id specified in IOInfo.

class app.processing.graph.ProgramGraph

Internal representation of the program graph.

class app.processing.graph.QubitInfo

Store QubitIDs of declarations and the various ancilla types.

Parameters:

  • declaration_to_ids – Maps declared names to corresponding qubits ids.

  • clean_ids – List of required reusable/fresh/uncomputed qubit ids.

  • dirty_ids – List of required (possible) dirty qubits.

  • reusable_ids – List of returned reusable qubits.

  • uncomputable_ids – List of qubits that are reusable after uncompute.

  • entangled_ids – List of qubits that are always returned dirty.

class app.processing.graph.ClassicalIOInstance

Single input/output from a snippet of type classical.

Parameters:

  • name – Name of the annotated variable.

  • type – Type of the annotated variable.

class app.processing.graph.QubitIOInstance

Single input/output from a snippet of type qubits.

Parameters:

  • name – Name of the annotated variable.

  • ids – List of annotated qubit ids.

class app.processing.graph.IOInfo

Input/output info for a single snippet.

Parameters:

  • inputs – Maps input-index to (Qubit/Classical)IOInstance.

  • outputs – Maps output-index to (Qubit/Classical)IOInstance.

class app.processing.graph.ProcessedProgramNode

Store a qasm snippet as string and AST.

Parameters:

  • raw – The corresponding ProgramNode.

  • implementation – The implementation as AST. Might be modified during processing.

  • io – Input/output information required for connections.

  • qubit – Qubit information required for optimization.
