qiskit.transpiler.passes.UnitarySynthesis
class UnitarySynthesis(basis_gates, approximation_degree=1)
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.
Parameters
- basis_gates (
List[str]) – List of gate names to target. - approximation_degree (
float) – closeness of approximation (0: lowest, 1: highest).
__init__
__init__(basis_gates, approximation_degree=1)
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.
Parameters
- 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. |
name() | 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. |
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.
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
name()
Return the name of the pass.
run
run(dag)
Run the UnitarySynthesis pass on dag.
Parameters
dag (DAGCircuit) – input dag.
Return type
DAGCircuit
Returns
Output dag with UnitaryGates synthesized to target basis.
