qiskit.quantum_info.Clifford.from_operator¶ classmethod Clifford.from_operator(operator)[source]¶ Create a Clifford from a operator. Note that this function takes exponentially long time w.r.t. the number of qubits. Parameters operator (Operator) – An operator representing a Clifford to be converted. Returns the Clifford object for the operator. Return type Clifford Raises QiskitError – if the input is not a Clifford operator.
