KMSSynthesisPermutation
class KMSSynthesisPermutation
Bases: qiskit.transpiler.passes.synthesis.plugin.HighLevelSynthesisPlugin
The permutation synthesis plugin based on the Kutin, Moulton, Smithline method.
This plugin can be accessed by the kms method name in the HLSConfig for permutation. For example:
from qiskit.circuit import QuantumCircuit
from qiskit.circuit.library import PermutationGate
from qiskit.transpiler import PassManager
from qiskit.transpiler.passes.synthesis.high_level_synthesis import HLSConfig, HighLevelSynthesis
from qiskit.transpiler.passes.synthesis.plugin import HighLevelSynthesisPluginManager
# Create a permutation and add it to a quantum circuit
perm = PermutationGate([4, 6, 3, 7, 1, 2, 0, 5])
qc = QuantumCircuit(8)
qc.append(perm, range(8))
# KMSSynthesisPermutation plugin for permutations
# Returns a quantum circuit with size 18 and depth 6
# but adhering to the linear nearest-neighbor architecture.
qct = PassManager(HighLevelSynthesis(HLSConfig(permutation=[("kms", {})]))).run(qc)
print(f"kms: {qct.size() = }, {qct.depth() = }")Methods
run
KMSSynthesisPermutation.run(high_level_object, **options)
Run synthesis for the given Permutation.
