Title: Modeling and Performance Evaluation of a Quantum Switch
Abstract: Entanglement is an essential component of quantum computation, information, and communication.  Its applications include quantum cryptography, distributed quantum computing, and quantum sensing. These applications drive the increasing need for a quantum switching network that can supply end-to-end entanglement to groups of endpoints that request them.  To realize such quantum systems, several architectures have been proposed to support high entanglement generation rates, high fidelity, and long coherence times.

In this keynote, we will focus on the most basic and fundamental component of a quantum network — a single quantum switch that serves k users in a star topology.  Each user  has  a  dedicated  link  connected  to  the switch. In the most general case, the switch serves n-partite entangled states to sets of  users  according  to  incoming  requests,  where n is less than or equal to k. To  achieve  this,  link-level  entangled states are generated across each link, resulting in two-qubit maximally-entangled states (i.e., Bell pairs or EPR states).  These qubits are stored at local quantum memories:  one from each Bell pair at the user and the other one at the switch.  We will consider the algorithm where the switch performs multi-qubit measurements to provide end-to-end entanglement to user groups of size n when enough of these bipartite states are accrued (at least n of them).

Various models and their main performance (e.g. stability, end-to-end entanglement rate, number of stored qubits at the switch) will be discussed under a number of structural  (e.g. finite/infinite storage capabilities, homogeneous/heterogeneous links), modeling (e.g. qubit decoherence) and statistical assumptions.

Keynote by Rosa M. Badia (homepage)

Bio: Rosa M. Badia holds a PhD on Computer Science (1994) from the Technical University of Catalonia (UPC). She is the manager of the Workflows and Distributed Computing research group at the Barcelona Supercomputing Center (BSC). She is considered one of the key researchers in Parallel programming models for multicore and distributed computing due to her contribution to task-based programming models during the last 15 years. The research group focuses on PyCOMPSs/COMPSs, an parallel task-based programming distributed computing, and its application to the development of large heterogeneous workflows that combine HPC, Big Data and Machine Learning. The group is also doing research around the dislib, a parallel machine learningn libray parallelized with PyCOMPSs.  Dr Badia has published near 200 papers in international conferences and journals in the topics of her research. She has been very active in projects funded by the European Commission in contracts with industry. She has been actively contributing to the BDEC international initiative and is a member of HiPEAC Network of Excellence. She received the Euro-Par Achievement Award 2019 for her contributions to parallel processing, the DonaTIC award, category Academia/Researcher in 2019 and the HPDC Achievement Award 2021 for her innovations in parallel task-based programming models, workflow applications and systems, and leadership in the high performance computing research community. Rosa Badia is the IP of eFlows4HPC.

Title: The eFlows4HPC approach for an easy development and
execution of workfows
Abstract: Computing infrastructures are evolving from traditional models to highly distributed environments that involve sensors, edge devices, instruments, etc, and,  as well, high-end  computing systems such as clouds and HPC clusters. A key aspect is how to describe and develop the applications to be executed in such platforms.

What is more, the use of data analytics and artificial intelligence in general is on high demand in current HPC applications. However, methodologies to develop workflows that integrate computational workloads with data analytics and artificial are not available. The eFlows4HPC project aims at providing workflow software stack and an additional set of services to enable the integration of HPC simulations and modelling with big data analytics and machine learning in scientific and industrial applications. The project is also developing the HPC Workflows as a Service (HPCWaaS) methodology that aims at providing tools to simplify the development, deployment, execution and reuse of workflows. The project will demonstrate its advances through three application Pillars with high industrial and social relevance: manufacturing, climate and urgent computing for natural hazards; these applications will help to prove how the realization of forthcoming efficient HPC and data-centric applications can be developed with new workflow technologies. The talk will present the motivation, challenges and project workplan.

DAY 3: 20.10.2022, 10.00 AM

Keynote by Dr Virginia d’Auria (homepage)
Bio: Virginia D’Auria works on continuous variable (CV), discrete variable (DV) and hybrid quantum optical systems,  with experimental and theoretical aspects. She graduated from the University of Naples “Federico II” in Physics of Matter. After her PhD in Naples under Salvatore Solimeno and Matteo G.A. Paris, she moved to the Laboratoire Kastler Brossel’s quantum optics group, and worked on CV free-space quantum optics and applications to quantum state generation, manipulation and characterization via homodyne detection and quantum state tomography, and on conditional state preparation and investigated in theory and experiments for quantum characterization of single-photon detectors in quantum engineering. After joining the group of Quantum Photonics and Information at INPHYNI, working on DV quantum communication and the generation, manipulation and detection of single photon quantum states for transmission and routing in fibre networks, shecoordinated the ANR project Emergence – CONNEQT and developed a research line on CV quantum optics relying on a full guided-wave approach for the generation and characterization of single and two mode CV non-classical states and their manipulation via hybrid detection systems. She leads an ANR project on the generation of hybrid entanglement between CV- and DV-encoded optical qubit (ANR – Hylight), and has co-authored over 22 papers and a book chapter, and was awarded a patent on remote entanglement source synchronization.
