BasicSynthesisPermutation¶

class BasicSynthesisPermutation[source]¶

Bases: qiskit.transpiler.passes.synthesis.plugin.HighLevelSynthesisPlugin

The permutation synthesis plugin based on sorting.

This plugin can be accessed by the basic 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))

# BasicSynthesisPermutation plugin for permutations
# Returns a quantum circuit with size 6 and depth 3
qct = PassManager(HighLevelSynthesis(HLSConfig(permutation=[("basic", {})]))).run(qc)
print(f"basic: {qct.size() = }, {qct.depth() = }")

Methods

run

Run synthesis for the given Permutation.
