Hi all,

Thanks a lot Kireeti for taking the minutes! Much appreciated.

Below are the minutes from the meeting. Please send any remarks/corrections be the end of next week at which point I would like to upload them.

# QIRG @ IETF 111

## Administrivia

Seminar scheduled for Sept

Discuss use case draft
3 expired drafts

## Kaushik C

Recap (versions 04-05-06-07 in quick succession)

### Sec 2
define EPR pairs,
entanglement swapping between a pair of EPR pairs A, B and C, D
    entangle AB, entangle CD, do a bell state measurement: now AD are an EPR pair
q teleportation
    send a qubit to a distant party via local ops at each end and classical communication

### Sec 3
apps: Q money, Q imaging, Q chemistry
    use "no cloning theorem" to create nonclonable q banknotes
    q imaging for sensing neural activity
    q chem app for NISC

### Sec 4
variants of QKD
    mitigation of side channel attacks on QKD devices

### Next steps
version 07 stable, all comments addressed (waiting for new comments)
else ready for last call

question (robin w): replace q sensor with q metrology (more inclusive)
???: is metrology actually more inclusive?
kaushik will research and pick a name
Woj: can you contrast q money with crypto currency?
KC: q money is physical money
RvM: EPR pair vs Bell pair: pick one consistent term
    (Bell pair seems to be the more useful and mathematically formulated one)
    (woj: also fits in with bell state)
RvM: MDI & xxx QKD, no good way to send across repeaters: should be in draft (KC agrees)
Woj: comments mostly cleanup, typos; draft getting there, close to RGLC
Diego: more than use cases, so should draft be renamed? (content is good)

## open floor discussion
any questions/comments on arch position paper/email?
    https://mailarchive.ietf.org/arch/msg/qirg/eej-Q0cEB7SB39C-cwblJ1nEQKU/
    http://rdvlivefromtokyo.blogspot.com/2021/05/a-quantuminternet-architecture-position.html
RvM: primary disc on mail list: alex & joe; RvM agrees with joe's replies
RvM: it's time to put pieces together for an architecture
    recursion for Q internet
    rulesets
    will work across a global internet
    managing resources inside a q repeater

Start from blog post, submit as paper to network conference
Please send comments on email thread, blog post, paper, etc -- bring to mailing list

RvM: purification; woj: distillation -- helpful to have one consistent term; may be different mathematically
    slight preference for distillation (KC, woj, RvM's post doc)
    consensus in room: distillation

Colin P: still early, there could be other q internetworking positions besides the one in the paper above.
RvM: will need a single internetworking position eventually, so interconnection can happen
    ruleset approach is general
Woj: 600M euros in EU to build q networks/internets (both?)
    plan is to have networks open to industry and researchers
    https://quantumdelta.nl/quantum-network/

Robin: in all QIRG sessions, every q network is accompanied by classical network
    will that be in the architecture
RvM: yes, primarily for control plane
Robin: will there be different approaches/philosophies in q networks?
    like different things to measure in bell pairs

KK: should I revive advertising entanglement draft?
Woj: shoot an email to mailing list

Woj: seminar announcement: 22 sep virtual QiRG session.
