Quantum Simulation promises insight into quantum physics problems which are beyond the ability to calculate with conventional methods. Quantum simulators can be built either using a ‘digital’ Trotter decomposition of the problem or by directly building the Hamiltonian in the lab and performing ‘analogue’ experiments. I will present here a different approach, by which the model to simulate a Quantum Field Theory emerges naturally from a completely different microscopic Hamiltonian. I will illustrate this in the example of the emergence of the Sine-Gordon quantum field theory from the microscopic description of two tunnel coupled super fluids [1]. Special emphasis will be put on how to verify such emergent quantum simulators and how to characterize them. Thereby I will present different tools: High order correlation functions and their factorization [1], the evaluation of the quantum effective action and the momentum dependence of propagators and vertices (running couplings, renormalization of mass etc ..) of the emerging quantum field theory [2] and quantum field tomography that points to a new way to read out quantum simulators [3] and our path to directly learn the quantum simulated Hamiltonian from the experimental data. Together they establish general methods to analyse quantum systems through experiments and thus represents a crucial ingredient towards the implementation and verification of emerging quantum simulators. As an example, I will report on measuring area laws of mutual information [4] in a quantum simulation of the Klein-Gordon model. Work performed in collaboration with the groups of Th. Gasenzer und J.
