Description du projet
Un pas de plus vers des processeurs quantiques évolutifs
Les ions piégés sont l’une des plateformes les plus prometteuses pour réaliser un ordinateur quantique pratique. Les atomes neutres complémentaires excités par laser jusqu’à l’état de Rydberg offrent des interactions très fortes et à longue portée, qui peuvent être exploitées pour réaliser des opérations rapides de portes quantiques. Le projet BRISQ, financé par l’UE, combinera les deux approches – des ions piégés excités par laser dans des états de Rydberg – afin de construire une plateforme physique très prometteuse pour accueillir un ordinateur quantique évolutif. Cette plateforme offre des temps de cohérence allant jusqu’à une minute, ainsi que des opérations de porte ultrarapides de l’ordre de 100 ns. Ces deux facteurs sont essentiels pour atteindre une profondeur de circuit et donc une complexité de calcul sans précédent.
Objectif
The goal of BRISQ is to realize a prototype of a fully scalable quantum computer which has the capability to run quantum algorithms with a circuit depth exceeding one million. Achieving this goal will deliver a breakthrough in quantum information processing and simulation. This will directly impact on current efforts of the industrial sector which seek to employ quantum technology for computational tasks, such as the design of materials and drugs, or various optimization problems - tasks that are also limited by possible computational depth.
Our technological approach exploits the interaction of trapped ions excited to electronically high-lying Rydberg states. The distinctive advantage of this platform is that it offers coherence times in the range of up to a minute together with fast entangling gate speeds on the order of 100 ns. These two factors are key for achieving an unprecedented circuit depth and thus computational complexity. Research on Rydberg-ion devices is performed solely in two European research labs, and the first nanosecond-timescale entangling gate based on this approach has been achieved by one of the members of the BRISQ consortium. This brings the consortium in a unique position and gives Europe a decisive lead for advancing the development of this new platform towards maturity. To facilitate this effort, the BRISQ project assembles a research consortium that consists of two experimental and two theoretical academic research groups. They are joined by the SME HQS and the industrial partner Infineon Technologies. This combination of expertise permits us to advance our ambitious project on a broad front, ranging from industrial grade hardware to user-driven quantum algorithms and compiler software, which can directly feed into simulation of physical models and potentially quantum chemistry.
