Agenda

1. Administrativia (5 min):

2. A multi-plane architecture for the Quantum Internet, inspired on the lessons learned from QKD deployments (20 min)

Speaker: Diego Lopez

Q&A
shota nagayama:

A:

3. DemoQuanDT: Controlling Quantum Key Distribution Networks (20 min)

Speaker: Martin Stiemerling

Scott: how do you know that the lessons learned from QKD are applicable
to entangled networks of the future?
A: We are also going to test entanglements but not in this project

4. The difficulty of Quantum Cryptography in presence of packet losses (20 min)

Speaker: Davide Li Calsi

Some protocols for authentication suffer from loss of information and
retransmission of the public key can leak the secret.
Remediations exists such as transmitting new qbits instead of
re-transmitting the same public key (multiple measurements are now
possible)

Scott: Where is the public key?
A: It is not a public key in the classical sense - it is called public
key because it is shared multiple times

Diego Lopez: Idea of certification, is this a first step towards
security assesmtne for quantum protocols? Encourage as a line of
working, security analysis for QKD protocols
2nd presenter: working on this.
JinHveock Choi: same team can work together

5. Quantum Internet Addressing (20 min)

Speaker: Marcello Caleffi

This talk is about the protocol stack. There are a lot of lessons
learned from QKD networks for entangled networks.
We focus on addressing (similar to the classical IP/addressing layer).
The core of the quantum internet is to be able
to entangle with the destination - which is different from the classical
case where you want to reach the destination.
In fact, you do not have a single destination, since each party
participating in the entanglement are gateways for your
communication.

Scott: no idea about advantage of having quantumness in the address.
give me a what problem might be.
A: once you have entanglement and superposition for security, I can keep
routing tables small. why do you want to restrict your addressing to be
classical?
Scott: if you want to be secure, you need to know who you are begin
secure with.

Diego: Coming back to the different stratum. This is in the quantum
stratum. (missed the point).
Marcello: most proposals focus on quantum dataplane. control plane is
classic. Personal curios in seeing of quantum control plane can provide
advantages about classical quantum plane.
Diego: You need fibers. Need classical connectivity.
Marcello: Need to have quantum links, can be mapped to classical
definition. If doing swapping, definition of connectivity changes
Diego: I am saying relationship between quantum layer patterns, and
fibers, need relationship in order to get security alligned.

JinHyeock Choi: Do you plan to use a different name for identity and
location or connectivity for quantum case?
A: Within a year that's the honest answer.

Shota Nagayama:
A: if we have quantum addresses and quantum routing tables, we need
quantum algorithm to process it and extract it. does this give an
advantage? who knows? but it's important to provide these kind of
questions to advance research. now we have a new resource quantum. how
can we use it?

6. Towards the integration of 6G and the Quantum Internet (20 min)
