Description du projet
Technologies quantiques évolutives à variables continues
Les systèmes quantiques à variables continues (VC) utilisent des observables physiques dont les valeurs numériques appartiennent à des intervalles continus. La génération et la manipulation récentes d’états groupés à VC, comprenant des milliers de modes intriqués, ouvrent la voie à des systèmes de calcul et de mise en réseau quantiques à VC évolutifs. Le projet CLUSTEC, financé par l’UE, s’efforcera de réaliser le plein potentiel de la technologie des états de cluster à VC en réalisant des percées conceptuelles et techniques dans trois directions différentes. Les chercheurs développeront dans un premier temps des plateformes optiques évolutives pour les états massifs de clusters à VC en recourant à des outils topologiques avancés. Ils développeront de nouveaux protocoles et algorithmes de calcul et de mise en réseau quantiques à VC induits par la mesure. Ils développeront enfin de nouveaux protocoles et technologies de correction d’erreurs quantiques à VC qui devraient faciliter la réalisation de technologies quantiques pratiques tolérantes aux pannes.
Objectif
Continuous variable (CV) quantum technologies have in recent years made significant impact on the fields of quantum communication, sensing, and computing, as signified by the detection of gravitational waves and demonstration of quantum advantage via Gaussian boson sampling. Moreover, the recent generation and manipulation of CV cluster states, comprising thousands of entangled modes, have direct implications for future developments of scalable CV quantum computing and networking systems. In CLUSTEC, we will pursue an interdisciplinary approach to unfold the full potential of CV cluster state technology by making conceptual and technical breakthroughs along three different directions. First, we will develop two complementary optical platforms for scalable generation of massive CV cluster states of different entanglement topologies and generation of hardware efficient error-correcting codes. The two systems will be based on a well-established low-loss fiber platform and the emerging, highly promising integrated photonics platform of thin-film Lithium Niobate. Second, we will develop and test radically new measurement-induced CV quantum computational and networking protocols and algorithms with certified quantum advantage and real-life applications. Third, we will explore and develop, theoretically and experimentally, novel quantum error-correcting CV protocols and technologies that facilitate the realization of practical fault-tolerant quantum technologies for quantum computing, communication and sensing with true scalability potential. With these activities, CLUSTEC will create a new path towards scalable quantum technologies and accelerate the development of practical quantum technologies with potentially radical impact on European society and economy. The results will pave the way for industrial uptake and exploitation in the near and long term, and in turn support the development of European leadership and autonomy in emerging strategic technologies.
