PermutationGate
class qiskit.circuit.library.PermutationGate(pattern)
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.
