Bases: [`qiskit.transpiler.passes.synthesis.plugin.HighLevelSynthesisPlugin`](qiskit.transpiler.passes.synthesis.plugin.HighLevelSynthesisPlugin "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:
|
|
|
|
```python
|
|
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() = }")
|
|
```
|
|
|
|
