Abstract: Over the past two decades there has been rapid development in technologies for both digital quantum computing and analogue quantum simulation. With progress towards quantum advantage for problems designed to test the quantum hardware, there is increasing focus on when we will observe a practical quantum advantage for relevant problems with applications in science and in industry. I will discuss the state of the art for simulation of many-body quantum problems, which can be explored either in digital or analogue quantum simulation. I will illustrate this with our recent analysis of the hardware requirements for quantum advantage of analogue quantum simulators with cold atoms over known classical computational methods. By solving for the microscopic dynamics (including using open systems techniques to account for noise and decoherence), we can understand how errors propagate and in which regimes the outcome of an analogue simulation will be reliable. I will compare this to the requirements for digital quantum computing in the same class of problems, and also illustrate possibilities to explore new classes of systems with long-range interactions based around unique features of neutral atom arrays.
