    Quantum based materials calculations are simulations because we use quantum mechanical models to reproduce how a material should behave and then calculate measurable properties from that model.
    The theory provides the equations, but the actual calculation is a numerical experiment performed on a computer.

    People often see them as purely theoretical because the starting point is quantum mechanics and there is no physical sample in front of us. Since the work involves equations and abstract concepts, it can feel more like theory than simulation.
