qiskit.opflow.primitive_ops.PauliOp.permute

PauliOp.permute(permutation)

Permutes the sequence of Pauli matrices.

Parameters

permutation (List[int]) – A list defining where each Pauli should be permuted. The Pauli at index j of the primitive should be permuted to position permutation[j].

Return type

PauliOp

Returns

A new PauliOp representing the permuted operator. For operator (X ^ Y ^ Z) and indices=[1,2,4], it returns (X ^ I ^ Y ^ Z ^ I).

Raises

OpflowError – if indices do not define a new index for each qubit.
