Dear Chonggang,

Somes feedback

1/ 4.3.  Control vs Data Plane Classification
 The internet draft "Principles for a Quantum Internet" doesn't seem to mention a native quantum control plan (i.e based on quantum communication, E.g quatum ping) : 

Control plane protocols for quantum networks will have  responsibilities similar to their classical counterparts, namely   drawing the network topology, resource management, populating data   plane tables, etc.  They will not manipulate quantum data themselves   and they operate by exchanging classical messages only.  Therefore   there is no separate quantum and classical control plane.  There is   only one network control plane.

Should we not make these two documents consistent?

2/ 6.2.  Requirements 
In coherence with "Quantum internet: A vision for the road ahead" and "Principles for a Quantum Internet" should it not be necessary to define system metrics making it possible to express the quality of service requirements expected by the quantum applications I.e expected entanglement fidelity,  loss tolerance, error tolerance, Bell pair rate, Bell pair traffic profil (i.e bursty profil. For example if we use satellite LEO to generate Bell pair we may be interested in wanting to know what would be the impact on applications of Bell pair transmission breaks during phases of non-visibility of the satellite by ground stations), latence, time synchronization of nodes, ...  ?

Best Regards

Dear QIRG,

Quantum internet use cases have been updated to address the comments received during IETF July meeting. Please refer to

We would like to get your feedback on this new version and if the use case draft can be considered for next steps.

Best regards,

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Quantum Internet Research Group RG of the IRTF.

        Title           : Applications and Use Cases for the Quantum Internet
        Authors         : Chonggang Wang

   The Quantum Internet has the potential to improve application
   functionality by incorporating quantum information technology into
   the infrastructure of the overall Internet.  In this document, we
   provide an overview of some applications expected to be used on the
   Quantum Internet, and then categorize them using various
   classification schemes.  Some general requirements for the Quantum
   Internet are also discussed.  The intent of this document is to
   provide a common understanding and framework of applications and use
   cases for the Quantum Internet.
