[Qirg] comments on the architecture draft

[Rodney Van Meter <[e-mail]>]

Wojtek,

About two weeks ago, I started working on a list of things I’d like to see in the draft, but I’m afraid I’m not going to be able to turn them into text and an actual pull request by Monday. My apologies.  A few are absolute nits, a few are rather big.

Put these on your TODO list, and maybe we can find time to work on them together F2F sometime during the week in Vancouver?

Comments for Wojtek on QIRG architecture I-D:

* overall, the flow and structure are much better than -00. I
  particularly like 6.2 now, though I'm not sure it's finished yet.
* additional refs:
  - Dur group (Pirker, Zwerger)
  - (more stuff from us, e.g. my book?)
  - Kimble
  - Mark Wilde
  - Jones on links?
  - all-optical?
  - triangle inequality for routing
  - Riefel
  - Simon on QEC
  - Dur review of purification
  - distributed algorithm zoo
  - something from Pan?
  - Broadbent
  - Gottesman
  - Wootters, Park, Ortigoso on no-cloning
* needs a little wordsmithing here and there at some point
* security needs work
* needs to talk about logical differences at network boundaries
  (differences in error management parallels the other two very well)
* should cover 1G, 2G, 3G
* "support tomorrow's dist q apps" is time-sensitive, and why
  is it different from the apps just above it?
* does doc accommodate all-optical links or paths?
* does doc describe 1G as a distributed computation?
  - important corollary: state along the path v. stateless forwarding
  - equally important corollary: resource reservation/multiplexing
* just a shade more on apps, as parallel I-D is developing
* describe time-skewed Bell pairs
* "Therefore, we cannot use the same methods known from
   classical computing for the purposes of error detection and
   correction." ==> without modification, though both codes derived
   from classical and wholy unique to quantum are known (cite Simon?)
  Overall, this paragraph needs work to be both more accurate and
  clearer.
  reconcile w/ later ACK that QEC exists
* "through a variety of checksums" -- not entirely accurate.
  how about "through both error detection and error correction mechanisms"?
* section on direct transmission needs work
  --> make it a subsection of 4.1, titled "inadequacy of direct
      transmission"?
* "challenges" v. "new challenges" is awkward
* use the name "Dirac's ket notation"
  (makes it easier for neophytes to find)
* expand CNOT first time it's used
* connection architecture v. network architecture
