Studying condensed matter physics on NISQ quantum computers

Studying condensed matter physics on NISQ quantum computers

Quantum computers promise to perform computations beyond the reach of modern computers with profound implications for scientific research. Due to remarkable technological advances, small scale devices are now becoming available for use. In our work we investigate the applications of noisy intermediate scale quantum (NISQ) devices in the study of condensed matter systems. These range from the digital simulation of non-equilibrium Hamiltonian dynamics, finding many-body ground states, crossing topological phase transitions, and analogue simulation of time-dependent Hamiltonians. Using the IBM Q quantum computers we demonstrate that, through the use of new quantum algorithms, these devices may in the near future provide a powerful toolset for studying complex quantum systems.
