PauliBasisChange.get_diagonalizing_clifford(pauli)

Construct a CircuitOp with only single-qubit gates which takes the eigenvectors of pauli to eigenvectors composed only of |0⟩ and |1⟩ tensor products. Equivalently, finds the basis-change circuit to take pauli to a diagonal PauliOp composed only of Z and I tensor products.

Note, underlying Pauli bits are in Qiskit endianness, so we need to reverse before we begin composing with Operator flow.

Parameters

pauli (Union[Pauli, PauliOp]) – the Pauli or PauliOp to whose diagonalizing circuit to compute.

Return type

OperatorBase

Returns

The diagonalizing CircuitOp.
