app.processing.merge.connections

Connect input/output by modifying the AST based on IOInfo.

Module Contents

class app.processing.merge.connections.SingleQubit

Give a qubit a unique ID in the whole graph.

Parameters:

• section_id – The UUID of the section the qubit occurred in.

• id_in_section – The Qubit ID based on the declaration order in the section.

class app.processing.merge.connections.ApplyConnectionsTransformer(section_id: uuid.UUID, io_info: app.processing.graph.IOInfo, qubit_info: app.processing.graph.QubitInfo, global_reg_name: str, qubit_to_index: dict[SingleQubit, int], classical_input_to_output: dict[str, str])

Replace qubit declarations and classical inputs with aliases.

Parameters:

• section_id (uuid.UUID) – The UUID of the currently visited section.

• io_info (app.processing.graph.IOInfo) – The IOInfo for the current section.

• qubit_info (app.processing.graph.QubitInfo) – The QubitInfo for the current section.

• global_reg_name (str) – The name to use for the global qubit register.

• qubit_to_index (dict[SingleQubit, int]) – Map qubits to the indexes in the global reg.

• classical_input_to_output (dict[str, str]) – Map classical declaration names to aliases to use.

id_to_qubit(id: int) → SingleQubit

Create a SingleQubit for the encountered ID.

Parameters:

id (int)

Return type:

SingleQubit

visit_QubitDeclaration(node: openqasm3.ast.QubitDeclaration) → openqasm3.ast.QASMNode

Replace qubit declaration with alias to leqo_reg.

Parameters:

node (openqasm3.ast.QubitDeclaration)

Return type:

openqasm3.ast.QASMNode

visit_ClassicalDeclaration(node: openqasm3.ast.ClassicalDeclaration) → openqasm3.ast.QASMNode

Replace classical declaration with alias to output if it is an input.

Parameters:

node (openqasm3.ast.ClassicalDeclaration)

Return type:

openqasm3.ast.QASMNode

app.processing.merge.connections.connect_qubits(graph: app.processing.graph.ProgramGraph, global_reg_name: str, input: app.processing.graph.ProcessedProgramNode | None = None) → int

Apply connections to the graph.

Parameters:

• graph (app.processing.graph.ProgramGraph) – The graph to modify in place.

• global_reg_name (str) – The name of the qubit reg to use in aliases.

• input (app.processing.graph.ProcessedProgramNode | None) – Optional input node: don’t modify it + IDs in the order of the declarations in this node.

Returns:

The size of the global qubit register.

Return type:

int
