Efficient verification of quantum computing architectures with bosons

About us

The project is funded by HORIZON-EIC-2022-PATHFINDERCHALLENGES-01 programme for 48 months and a maximum grant amount of 3 984 885€. The project is composed of four European research institutions (CHALMERS TEKNISKA HOGSKOLA AB in Sweden, Sorbonne Université, Universita degli studi di Milano and coordinated by INRIA). The Veriqub project has the ambition to guarantee the reliability and precision of new quantum architectures. Quantum devices offer great promise for computation, cryptography, communication, and sensing. Alternative approaches to quantum information processing in which bosonic modes are the carriers of information have attracted increasing attention, because they offer a hardware-efficient path to fault-tolerance and scalability thanks to their inherently large Hilbert space. However, this poses the problem of providing rigorous guarantees of the correct functioning of these promising bosonic architectures, a task known as quantum verification. To date, this verification is performed by general-purpose tomographic techniques, which rapidly become intractable for large quantum systems. Thus, other methods are needed as quantum devices are scaled up to achieve real-world advantages. Veriqub aims to develop a new approach to the efficient verification of quantum computing architectures with bosons, using continuous-variable measurements. The name of this research project stands for "efficient Verification of Quantum computing architectures using Bosons". “Bosons” are physical systems that are used as carriers of information, for example, the photons that make up the light of a laser. The main objective of the project is to propose an efficient toolbox for verifying the reliability of quantum computing architectures using bosons. These architectures suffer from reliability issues, even though they could soon outperform conventional computers.
