Dear QIRG, Dear Wojtek

The document begins to provide a homogeneous and coherent overall system vision. After a first reading however, I have some comments :

1/ 5.5.  Physical constraints
With linear optics, it is not possible to detect perfectly the 4 states of Bell. There are methods to measure 3 of the 4 Bell states, but the probability of success is lower than the two-state method : 

Shouldn't we mention this constraint ?

2/ 5.1.  Challenge - 3.  An entangled pair is only useful if the locations of both qubits are known ... A relevant pair identifier, a means of communication between the pair owners, and an association between the pair ID and the individual qubits is sufficient.
Axel had opened an interesting debate on  "Naming and addressing in a quantum network".  For the ID "node Bruno" had proposed the use of the IP address. For the ID node Bruno had proposed the use of the IP address, but the debate on the identification of Bell pairs "link layer" remained open to take In account node with multi-interface (automated repeater or controllable quantum nodes) and the possibility on the same interface to swap differently the qubit of the pairs of "bell" generated by the  quantum links to which the interface is attached.  

Shouldn't there be a dedicated paragraph presenting this addressing and naming problem/challenge in a quantum network ? 

3/ 5.5.2.  Rate 
Shouldn't there be a paragraph devoted to the definition of metrics to define what the quality of service of quantum communications could be? or should it rather be in the document draft-irtf-qirg-quantum-internet-use-cases-02.txt 

Best regards

Dear QIRG,

I have just updated the draft-irtf-qirg-principles. Please see:

This version now includes changes from the last round of feedback after the last meeting and finally an expanded list of references as well.

This version is now ready for a final review by the RG while I figure out the next steps to finalise its submission for RFC status. So those of you who have only been following updates and discussions, now is a good time to give it a full read.

A new version of I-D, draft-irtf-qirg-principles-05.txt has been successfully submitted by Wojciech Kozlowski and posted to the IETF repository.

Name:		draft-irtf-qirg-principles
Revision:	05
Title:		Architectural Principles for a Quantum Internet
Document date:	2020-09-29
Group:		qirg
Pages:		37

   The vision of a quantum internet is to fundamentally enhance Internet
   technology by enabling quantum communication between any two points
   on Earth.  To achieve this goal, a quantum network stack should be
   built from the ground up to account for the fundamentally new
   properties of quantum entanglement.  The first realisations of
   quantum networks are imminent, but there is no practical proposal for
   how to organise, utilise, and manage such networks.  In this memo, we
   attempt to lay down the framework and introduce some basic
   architectural principles for a quantum internet.  This is intended
   for general guidance and general interest, but also to provide a
   foundation for discussion between physicists and network specialists.


Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at
