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 subclass.

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

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