PermutationGate
class PermutationGate(pattern)
Bases: qiskit.circuit.gate.Gate
A gate that permutes qubits.
Return a permutation gate.
Parameters
pattern (List[int]) – permutation pattern, describing which qubits occupy the positions 0, 1, 2, etc. after applying the permutation, that is pattern[k] = m when the permutation maps qubit m to position k. As an example, the pattern [2, 4, 3, 0, 1] means that qubit 2 goes to position 0, qubit 4 goes to the position 1, etc.
Raises
CircuitError – if permutation pattern is malformed.
