PermutationGate#

class qiskit.circuit.library.PermutationGate(pattern)[source]#

Bases: 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.
