Efekan Kökçü (North Carolina State University) - Quantum Simulation of Many Body Systems

Simulating many body systems/models has been a great tool for us to understand the nature of materials. It comes with three parts: state initialization, time evolution and data analysis. Since the Hilbert space dimension depends on the system size exponentially, conventional computation has been limited to brilliant approximations or small systems. Quantum computers however, in theory, do not have these limitations, and have potential to enable us to simulate relatively large many-body systems. In practice, current quantum computers are still very noisy, which requires us to compress/shorten our quantum circuits as much as possible. Our research is focused on generating efficient quantum algorithms for every aspect of quantum simulation, including time evolution and computation of response functions.
