This data was generated during simulations and numerical calculations for the paper titled "Measurement of Many-Body Quantum Correlations in Superconducting Circuits." The data was generated using publicly known quantum physics, and well known numerical methods. Filenames include names of figures used in the manuscript.

We propose a probe circuit capable of reading out many-body correlations in an analog quantum simulator. Our measurement scheme, designed for many-photon states, exploits the non-linearity of the Josephson junction to measure two-point (and potentially higher-order) correlation functions of the superconducting phase operator. We demonstrate the capabilities of this design in the context of an LC-ladder with a quantum impurity. The proposed probe allows for the measurement of inherently quantum correlations, such as squeezing, and has the potential to significantly expand the scope of analog quantum simulations using superconducting circuits.
