GaussianHCRB-SDP

The notebook GaussianHCRB-Applications.ipynb contains the SDP to compute the Holevo Cramér-Rao bound for Gaussian quantum states, as explained in arXiv:2504.17873 by S. Chang, M. G. Genoni and F. Albarelli. The code is applied to the two applications discussed in the paper and reproduces the two figures in the manuscript.

[!IMPORTANT]
This code relies on cvxpy, numpy and matplotlib for plotting, the mosek package is also used as a solver, but it's optional.
