The many-body simulation of a QPU at the level of the Hamiltonian and pulses requires the integration of different tools leading to a simulation that encompasses different aspects and their interplay. In the example of a Rydberg atom QPU, we demonstrate how tensor network simulations can be used to gain insight into the system. Therefore, we employ an integration of an effective description of strontium-88 atoms, optimal control methods, a dedicated compiler, and tree tensor networks. To show the power of this tool, we focus on how benefits from parallelization of a quantum algorithm scale with the system size.
