Purpose

The project targets the analysis and development of novel quantum algorithms for scalable quantum computing under realistic hardware errors. The first theme seeks the development of detailed models of physical errors, tracking how they propagate through different architectures and quantum error correction codes, to characterize the residual logical level errors. These realistic error models will be used to understand the limits and opportunities for quantum algorithms on both near-term uncorrected devices and future error-corrected quantum processors. The second theme seeks to focus on the simulation of quantum localization, an important phenomenon that underpins questions about metal-insulator transitions and the thermalization of disordered interacting systems, which offers promise of intrinsic robustness to certain classes of errors. The project will leverage these two themes to optimize the co-design of simulation algorithms under expected physical and logical error models, to identify the most promising routes for algorithms simulating localization.
