The classical part means sending the result of a measurement, so 0 or 1 and not some state like $\alpha|0>+\beta|1>$ (where the qubit is a 0 with probability $\alpha$ and a 1 with probability $\beta$ - even if it's something that closely resembles classical information like $1|0> + 0|1>$, so a 100% probability to measure 0 - but that's still ...
