Romain Alléaume graduated from ENS Paris in 2002 and from Télécom Paris in 2004. He completed his PhD, from Paris VI University in 2004 and was co-recipient of “magazine La Recherche” scientific prize. He then joined Telecom Paris and coordinated the activity on QKD performed within the European FP6 project SECOQC. Romain Alléaume co-founded the start-up company SeQureNet that developed, and successfully commercialized the first continuous-variable quantum key distribution (CV-QKD) system in 2013. Currently he is actively involved in the European Quantum Technology Flagship (OpenQKD, Quantum Secure Network Partnership), the EuroQCI program (ParisRegionQCI, FranceQCI) as well as in French PEPR Quantique (QCommTestbed). He is leading a research activity on quantum and classical cryptography, quantum networks and photonic quantum information processing as well as on cross-disciplinary topics linking quantum information with cryptography, photonics and security.

Cambyse Rouzé’s research is focused on the mathematical analysis of complex quantum systems and their use for quantum information processing. His area of expertise includes quantum information theory with discrete and continuous variable systems, entropic inequalities, quantum spin systems at finite temperature and dissipative dynamics. More recently, he has been interested in questions related to the thermal stability of quantum memories and the complexity of quantum many body states. He received his PhD in 2019 from the Department of Pure Mathematics and Mathematical Statistics at the University of Cambridge, UK, under the supervision of Nilanjana Datta. He was then a Humboldt postdoctoral fellow at the Technical University of Munich in the group of Robert König where he won a grant from the Munich Center for Quantum Science and Technology as a junior group leader. In September 2023, he joined QURIOSITY as an Inria Starting Faculty Researcher.

Augustin Vanrietvelde’s research focuses on the study of quantum theory’s compositional and causal structures, with a mathematical and formal approach. He has worked on quantum causal models, coherent control, quantum computation architectures, indefinite causal order, and quantum reference frames. Most recently, he has been focusing on the mathematical underpinnings of causal structures in quantum theory, and on compositional structures in the presence of symmetry. He did his PhD within the University of Oxford’s Quantum Group, under the supervision of Jonathan Barrett, Giulio Chiribella, and Bob Coecke. He was then as a postdoctoral researcher at the ENS Saclay’s Quacs group before joining Télécom in 2023, as an assistant professor in the Quriosity team.

Peter received his PhD in 2019 from the Department of Mathematics at the University of York, UK, under the supervision of Roger Colbeck, for which he has been awarded the Anand Ramachandran Memorial Prize for the best PhD thesis. He was then a postdoctoral researcher at Inria, ENS de Lyon in the group of Omar Fawzi and in 2021 he joined the IQA group as an assistant professor. His research mainly focuses on the theoretical development of quantum cryptographic protocols (in particular those of a device-independent nature) and is interested in the application of convex optimization techniques to quantum information in general.

Thomas previously received his PhD from the University of Brussels in 2019, under the supervision of Stefano Pironio. He then moved to Canada, where he was a postdoctoral researcher in the groups of Norbert Lütkenhaus (University of Waterloo) and Hoi-Kwong Lo (University of Toronto). He is interested in all aspects of Quantum Cryptography; from the design of practical implementations using Quantum Optics, to advanced security methods for proving finite-size security. He is interested in both numerical and analytical methods, and has experience with different adversarial models, from Device-Dependent to (semi-)Device-Independent security.

I graduated in theoretical physics at the University of Pisa in 2019. I joined the IQA group in 2019 and I am currently working on Quantum Communication Complexity, Cryptography and Multimode Quantum Optics, under the joint supervision of Romain Alléaume and Sylvain Gigan at ENS Paris. I did my Master thesis at Scuola Normale Superiore on Quantum Batteries, more specifically on optimal methods for charging Quantum Batteries in finite time. Besides physics, I also love playing tennis and I am passionate about photography. I am still figuring out how my camera works, but I am really enjoying it.

Guillaume is currently working on quantum coherent communications and digital processing, under the co-supervision of Romain Alléaume and Yves Jaouen, and in collaboration with Quandela, with a PhD grant co-funded by the the Paris Region PhD program.

Jan received a Masters degree in Theoretical and Mathematical Physics from the Technical University of Munich and the Ludwigs-Maximilians University in 2023 and another in Applied Mathematics from the University of Cambridge in 2022. He is working under supervision from Cambyse Rouzé and co-supervision of Omar Fawzi on analytic and algorithmic approaches to strong data processing in complex quantum systems. In particular establishing such inequalities for physical systems to study quantum many-body thermalization. His general academic interest lie in the intersection of (infinite dimensional) analysis and quantum theory with applications to mathematical statistical physics and quantum information theory. His PhD grant is funded by IP Paris.

Marco’s research focuses on the application of CV-QKD in the context of telecom networks. His PhD is funded by Orange Labs under the co-supervision of Paulette Gavignet and Nicolas Brochier and by Télécom Paris under the co-supervision of Yves Jaouen and Romain Alléaume. For his Master thesis, he built a polarisation alignment unit for a DV-QKD satellite downlink. My favourite sports are playing tennis, going sailing, diving and climbing.

I graduated in Computer Science from Imperial College London in 2020 and from Télécom Paris in 2021. My research focuses on computational models in quantum cryptography. In particular, I’m interested in trying to remove some classical required hypotheses of cryptography schemes to replace them with more fundamental assumptions.
