Description
In this talk I will provide a tutorial introduction to quantum simulation with quantum computers. I will review the failure of conventional computing to address many-body problems and how this prevents progress in many scientific areas. I will discuss whether and how quantum computers, either fault tolerant in the future or noisy intermediate scale state of the art, can help to solve many-body problems. I will present the main challenges for quantum simulation algorithms: quantum state preparation, dynamical evolution and post-processing, including some recent work of my group [1,2,3]
