Abstract:
Numerical simulation has become an indispensable tool in modern science and engineering, especially in domains where direct experimental investigation is expensive, limited, or impossible. In the simulation of interacting quantum systems, however, classical numerical methods face a fundamental difficulty: the dimension of the underlying Hilbert space grows exponentially with system size. This curse of dimensionality makes exact approaches infeasible for many physically and chemically relevant systems, including strongly correlated materials and multireference molecular systems. As practical quantum computers are not yet available as general-purpose replacements for classical high-performance computing, the simulation of such systems continues to rely on advanced classical algorithms and their efficient implementation on modern hardware. The theoretical research presented in this talk focuses on the development of massively parallel algorithms that employ novel mathematical methods based on the laws of quantum mechanics, together making it possible to simulate systems more complex than ever before, to predict their behavior, and to design their properties.
