def tensor(self, other):
return self._tensor_product(other, reverse=False)<EOL>
Return the tensor product channel self ⊗ other.

        Args:
            other (QuantumChannel): a quantum channel.

        Returns:
            SuperOp: the tensor product channel self ⊗ other as a SuperOp
            object.

        Raises:
            QiskitError: if other cannot be converted to a channel.
