Abstract:We discuss recent progress in building, and programming quantum computers and quantum simulators. Our focus is on quantum optical systems of atoms and ions manipulated by laser light, providing prime examples of quantum systems, which can be controlled on the level of single quanta. This includes trapped ions as a universal quantum processor, and digital and analog quantum simulation of strongly correlated quantum matter with optically trapped atoms. The talk presents examples taken from recent collaborative theory-experiment research, where trapped-ion quantum simulators are programmed in the `Innsbruck quantum cloud’. Specific topics include variational quantum simulation demonstrating classical-quantum algorithms, running `randomized’ measurement protocols quantifying entanglement, and (cross-) verification of intermediate scale quantum devices.We discuss recent progress in building, and programming quantum computers and quantum simulators.
