Hi Chonggang,

Thank you for taking the remarks into account.

4.2 "Programming quantum multicomputers require exploiting quantum teleportation but also only entanglement (or even multi-entanglement for multi-party computation) without the need of teleportation. Isn't it ?"
[CW] - We were trying to use this case to show that quantum teleportation (as one of approaches) can be used to support distributed quantum computing; as a result, entanglement is needed (i.e. for teleportation). But as you commented, non-teleportation-based approach could also enable distributed quantum computing/multi-party computation. Wonder if I misunderstood your question.
[PG] It was a question.  Does distributed measurement-based quantum computing require teleportation function to perform distributed computing ?  In the measurement-based model, quantum computation is driven by single-site measurements on a large entangled quantum state known as a cluster
state. The generation of the distributed cluster state may require the implementation of repeater which is based on teleportation, but what about the distributed computation base on measurement only ?


For information : Concerning "Quantum Key Distribution" ETSI has also produced use cases.: https://www.etsi.org/deliver/etsi_gs/qkd/001_099/002/01.01.01_60/gs_qkd002v010101p.pdf

Hi Gelard,

Thank you again for your good comments/questions. We have revised the use case document according to all feedback from you and a few other people. The v01 was just uploaded and can be accessed from the following link.
https://tools.ietf.org/html/draft-wang-qirg-quantum-internet-use-cases-01

Answers to your comments/questions are also provided below. Would you please review v01 and our answers and let us know if your comments have been addressed? If you have any new comment, we will be happy to address it and improve the document furthermore.

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?"
[CW] - We rewrote and expanded section 4 to further clarify the concept of control plane.  We believe that QKD is similar to SIP and other control plane functions in the classic Internet.

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)"
[CW] - We created a new section 4.3 "Other Possible Classifications" to reflect your points. If you have more specific comments, we would like to incorporate them into and enhance 4.3 furthermore.

3. Concerning QKDN there also this presentation https://www.itu.int/en/ITU-T/Workshops-and-Seminars/2019060507/Documents/Hao_Qin_Presentation.pdf
[CW] - Thanks for bringing this presentation to our attention. We added this reference and revised the description on "large-scale QKD" in section 5.1.

4. "Remark concerning the Use case 5.2.  Distributed Quantum Computing:
4.1 "2.  The quantum computer A first establishes a shared entanglement with the quantum computer B (i.e., there are two entangled bits: |q1> at A and |q2> at B).". The computer A Established a shared entanglement with the quantum computer B in the sense of a connection Setup  defined in the draft-van-meter-qirg-quantum-connection-setup-00 ?"
[CW] - In general, the answer is yes. But if A and B are one-hop away and can directly exchange qubits reliably, complex connection setup may not be needed.

4.2 "Programming quantum multicomputers require exploiting quantum teleportation but also only entanglement (or even multi-entanglement for multi-party computation) without the need of teleportation. Isn't it ?"
[CW] - We were trying to use this case to show that quantum teleportation (as one of approaches) can be used to support distributed quantum computing; as a result, entanglement is needed (i.e. for teleportation). But as you commented, non-teleportation-based approach could also enable distributed quantum computing/multi-party computation. Wonder if I misunderstood your question.

state. The generation of the distributed cluster state may require the implementation of repeater which is based on teleportation, but what about the distributed computation base on measurement only ? 

4.3. Can we decline orders of magnitude of requirements such as entangled qubits rate, Quantum Bits Error Rate, ... ?
[CW] - Good question! This may need more investigations. We will consider these metrics in future version(s).

Best regards,
Chonggang

Hi,

Remark concerning the Use case 5.1.  Secure Communication Setup.

1/  Quantum Key Distribution(QKD);Components and Internal Interfaces : https://www.etsi.org/deliver/etsi_gr/QKD/001_099/003/02.01.01_60/gr_QKD003v020101p.pdf

NOTE: Entanglement-based schemes where entangled states are prepared externally to Alice and Bob are not normally considered "prepare-and-measure". Schemes where entanglement is generated within Alice can still be considered "prepare-and-measure". Send-and-return schemes can still be "prepare-and-measure" if the information content from which keys will be derived is prepared within Alice before being sent to Bob for measurement.

2/ A series of loopholes have been identified due to the imperfections of measurement devices. There are several solutions to take into account these attacks such as for example measurement-device-independent quantum key distribution https://arxiv.org/abs/1912.09642  This operational solutions can work differently than the steps of BB84 protocol.

3/ It would be necessary to be able to extract the requirements on the networks. For this use case you consider that the targeted step is "prepared and measured" ( https://pure.tudelft.nl/portal/files/47533107/qim_final_V7_FINAL.pdf ) ? And thus no need  entanglement distribution for long distance  ? The need for this use case is to have QKD Network base on trusted relays to take in account long distance communications  ?

I have not yet read in detail the use cases

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.
