PauliBasisChange.convert¶

PauliBasisChange.convert(operator)[source]¶

Given a PauliOp, or an Operator containing PauliOps if _traverse is True, converts each Pauli into the basis specified by self._destination and a basis-change-circuit, calls replacement_fn with these two Operators, and replaces the PauliOps with the output of replacement_fn. For example, for the built-in operator_replacement_fn below, each PauliOp p will be replaced by the composition of the basis-change Clifford CircuitOp c with the destination PauliOp d and c†, such that p = c·d·c†, up to global phase.

Parameters: operator (OperatorBase) – The Operator to convert.
Return type: OperatorBase
Returns: The converted Operator.
