Hi all,

I started going through the new draft and I have some questions that would help me before I progress further:
* I am struggling to understand the difference between Quantum Subnetwork and Quantum Internet. Is the difference the same as between a classical subnetwork and the classical Internet? The definitions in the text are too vague for me.
* Additionally, some further comments in-line below in response to Patrick's comments.

[WK] Patrick is right. It would be beneficial to get these two documents consistent and he is also right that with the latest changes I made I seem to exclude a quantum ping from the control plane. This is worth picking up on. As a start, a question to everybody: is the definition in the principles draft too strict then?

[WK] I think these numbers would be great, but really hard to come up with without a more detailed analysis. However, identifying which stage an application requires is already quite informative in terms of requirements. For example, identifying whether we only need a "quantum memory" stage network vs "fault-tolerant" already tells us a lot.
