# qiskit.transpiler.passes.UnitarySynthesis¶

class UnitarySynthesis(basis_gates, approximation_degree=1)[código fonte]

Synthesize gates according to their basis gates.

Synthesize unitaries over some basis gates.

This pass can approximate 2-qubit unitaries given some approximation closeness measure (expressed as approximation_degree). Other unitaries are synthesized exactly.

Parâmetros
• basis_gates (List[str]) – List of gate names to target.

• approximation_degree (float) – closeness of approximation (0: lowest, 1: highest).

__init__(basis_gates, approximation_degree=1)[código fonte]

Synthesize unitaries over some basis gates.

This pass can approximate 2-qubit unitaries given some approximation closeness measure (expressed as approximation_degree). Other unitaries are synthesized exactly.

Parâmetros
• basis_gates (List[str]) – List of gate names to target.

• approximation_degree (float) – closeness of approximation (0: lowest, 1: highest).

Methods

 __init__(basis_gates[, approximation_degree]) Synthesize unitaries over some basis gates. Return the name of the pass. run(dag) Run the UnitarySynthesis pass on dag.

Attributes

 is_analysis_pass Check if the pass is an analysis pass. is_transformation_pass Check if the pass is a transformation pass.
property is_analysis_pass

Check if the pass is an analysis pass.

If the pass is an AnalysisPass, that means that the pass can analyze the DAG and write the results of that analysis in the property set. Modifications on the DAG are not allowed by this kind of pass.

property is_transformation_pass

Check if the pass is a transformation pass.

If the pass is a TransformationPass, that means that the pass can manipulate the DAG, but cannot modify the property set (but it can be read).

name()

Return the name of the pass.

run(dag)[código fonte]

Run the UnitarySynthesis pass on dag.

Parâmetros

dag (DAGCircuit) – input dag.

Tipo de retorno

DAGCircuit

Retorna

Output dag with UnitaryGates synthesized to target basis.
