This repository gives an example Julia implementation of the numerical method proposed in the paper Correlation functions for realistic continuous quantum measurement (https://arxiv.org/abs/2212.00176).
The code to compute the two-point correlation function of the signal integrated on constant overlapping windows is self-contained in the binned-theory.jl script. The Jupyter notebook leaky-cavity.ipynb gives an example on a toy model (a leaky cavity monitored by a diffusive SME in a rotating frame, see figure below).
Dependencies Only the KrylovKit.jl library is required to run the binned-theory.jl script. Other libraries are required for the example notebook, see Project.toml for the complete list.
