# Agenda

## 1. Administrativia (5 min):

- Resolving any online issues
- RG update
- Relevance of QKD to the QIRG

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

**Speaker:** Diego Lopez

**Abstract:** A consistent framework for the integration of the protocols applicable to the Quantum
Internet has to satisfy three essential requirements: agility, so it is able to adapt to the
evolution of quantum communications base technologies, sustainability, with open availability in
technological and economical terms, and pliability, being able to integrate with the operations and
management procedures in current networks. Such an architecture framework will be introduced, based
on the already extensive experience in the deployment of QKD network infrastructures and related
initiatives on the integration of network infrastructures and services.

**Speaker bio:** Diego R. Lopez joined Telefonica I+D in 2011 as a Senior Technology Expert and is
currently in charge of the Technology Exploration activities within the GCTIO Unit. Before joining
Telefónica he spent some years in the academic sector, dedicated to research on network services,
and was appointed member of the High-Level Expert Group on Scientific Data Infrastructures by the
European Commission. Diego is currently focused on applied research in network infrastructures, with
a special emphasis on virtualization, data-driven management, new architectures, security, and
quantum communications. Apart from this, Diego is a more than acceptable Iberian ham carver, and
extremely fond of seeking and enjoying comics, and good discussions on any (in)appropriate matter.

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

**Speaker:** Martin Stiemerling

**Abstract:** The DemoQuanDT project, a German national project, aims at installing a Quantum Key
Distribution Network (QKDN) across Germany from the city of Bonn to Berlin. The da/net research
group of the Darmstadt University of Applied Sciences implements the control of this QKDN network
and some experimental Key Management Systems (KMS) for the secured key forwarding. The talk will
give a project architecture overview, an implementation status (including a first QKDN-emulator) and
also about some of the research challenges.

**Speaker bio:** Martin Stiemerling is a computer science professor at the Darmstadt University of
Applied Sciences and the co-lead of the da/net research group. Hi interests are in Quantum Key
Distribution Networks, Software Defined Networking, Trusted/Zero-Trust-Networks, and open standards.
He leads the goSDN project that is developing a model-driven SDN controller and the corresponding
gnmi-target. He has been an active contributor to the IETF and IRTF, and served as Transport Area
Director at the IETF from March 2012 to March 2016.

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

**Speaker:** Davide Li Calsi and Paul Kohl

**Abstract:** Quantum cryptography has been a fertile research direction that produced several
protocols promising high security levels. Despite such results holding in theory, the
characteristics of real networks can open the door to unforeseen attack vectors. We analyze some of
the most popular protocols of quantum cryptography and describe new vulnerabilities and attacks when
the loss of entire strings of qubits is possible. We also show some established protocols that are
resilient to these attacks, and propose some mitigations based on quantum teleportation.

## 5. Quantum Internet Addressing (20 min)

**Speaker:** Marcello Caleffi

**Abstract:** The design of the Quantum Internet protocol stack is at its infancy and early-stage
conceptualization. Yet the underlying assumption of the existing proposals is that they implicitly
mimic classical Internet Protocol design principles: "A name indicates what we seek. An address
indicates where it is. A route indicates how to get there". This talk aims at pointing out that this
twofold assumption of classical and location-aware addressing constitutes a restricting design
option.

**Speaker bio:** Marcello Caleffi co-leads the Quantum Internet research group at University of
Naples Federico II. His work appeared in several premier IEEE Transactions and Journals, and he
received multiple awards, including best strategy, most downloaded article, and most cited article
awards. Currently, he serves as editor for IEEE Trans. on Wireless Communications and IEEE Trans. on
Quantum Engineering. In 2017, he has been appointed as distinguished lecturer from the IEEE Computer
Society and, in 2023, hehas been appointed as distinguished lecturer from the IEEE Communications
Society. In 2019, he has been also appointed as member of the IEEE New Initiatives Committee from
the IEEE Board of Directors. In 2022, he has been awarded with the IEEE Communications Society "Best
Tutorial Paper Award" 2022 for the paper "When Entanglement Meets Classical Communications: Quantum
Teleportation for the Quantum Internet".

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

**Speaker:** Riccardo Bassoli

**Abstract:** 6G networks are now researched and design to prepare their standardisation phase and
deployment from 2030. In parallel, around 2018 the research and design of the Quantum Internet has
started to prepare its standardisation and initial realisation in the next decade. Can these
networks coexist and co-work to have a mutual benefit? What use cases can benefit from the
integration between 6G and the Quantum Internet? The talk briefly shows the current effort at TU
Dresden with its academic and industrial partners towards the realisation of the first 6G-quantum
network.

**Speaker bio:** Riccardo Bassoli is an Assistant Professor at the Deutsche Telekom Chair of
Communication Networks and Head of the Quantum Communication Networks Research Group, at the Faculty
of Electrical and Computer Engineering, at Technische Universität Dresden. He is member of the
Centre for Tactile Internet with Human-in-the-loop (CeTI) , Cluster of Excellence, Dresden. He is
also member of the EU Quantum Internet Alliance (QIA) and of the EU flagship for 6G Hexa-X II. He is
principal investigator in the 6G-life research hub of Germany. He got his Ph.D. from 5G Innovation
Centre at University of Surrey (UK), in 2016. He was also a Marie Curie ESR at the Instituto de
Telecomunicações (Portugal) and visiting researcher at Airbus Defence and Space (Elancourt, France).
Between 2016 and 2019, he was postdoctoral researcher at Università di Trento (Italy). He is member
of the Glue Technologies for Space Systems Technical Panel of the IEEE AESS. He is also co-founder
and managing director of QcomBIT GmbH.
