Hi Patrick,

Thank you for reading our draft and providing your feedback. I will look into the references you mentioned below and think about "control plane application concept" and "application classification". I will get back to you via the ML and an update to the draft.

Best regards,
Chonggang

Hi Chonggang,

Thank you, it is an Interesting initiative.

1/The concept of "Control Plane Applications" is indeed not clear.

For example In the list " Control Plane Applications using Quantum Internet:" there is not the control plan to select a path to distribute entanglement or quantum keys in the context of QKD network based on trusted nodes (Key relai : https://www.itu.int/en/ITU-T/Workshops-and-Seminars/2019060507/Documents/Masahiro_Takeoka%20_V2_Presentation.pdf ). And so this does not belong to the application control plan ?


2/ There can be different axes of classification of application services requiring a quantum internet, who can bring other complementary looks.

For example by industry sector like Quantum computing, Quantum metrology, Quantum sensor, Quantum telecom, ..., from which it is possible to decline use cases with specific need (e.g : Distributed quantum sensing - https://arxiv.org/abs/1910.14156 ; Networked quantum sensing - https://arxiv.org/abs/1702.04271 ; Distributed quantum computing - https://arxiv.org/pdf/1810.08421.pdf , https://www.researchgate.net/publication/2192461_Distributed_quantum_computing_A_distributed_Shor_algorithm ; One-Way Quantum Computing in distributed architectures - https://arxiv.org/abs/0906.2725 ; ... etc)

I have not yet read in detail the use cases

Best Regards
/Patrick

Hi Wojciech,

Thank you for your feedback and good questions on our use case draft.

We will look into your questions and answer them in the mailing list and on a fast update of the draft.

Best regards,

Hi,

Great work on starting with a use case draft! It will definitely be useful.

I'm still going through the text so I can't provide a full commentary/feedback, but I do already have one question:

You separate applications into control and data plane applications. However, it's not clear to me what exactly separates the two groups. Could you expand on that?

And one other important point about the end-node definition.

You write in your end-node definition that that it must be a quantum computer.
That is not the case. An end-node without full fault-tolerant capabilities, a quantum memory, or even a universal gate set is still useful. For QKD you don't even need to store the qubits at the end-nodes (prepare-and-measure stage in Wehner's Quantum Internet paper). Perhaps this is what you had in mind when you wrote quantum computer, but it is important to make it clear that end-nodes don't have to be as capable as quantum routers/repeaters.

You also write that classical connectivity in the end-node is optional. I can't think of any application that would not need classical connectivity as well to coordinate with the application's remote. In general, I would say that all quantum network connected nodes also have classical connectivity.

Other than that, I'm still slowly going through the draft.
