taisanul/qet_lhc: Quantum energy teleportation in near-critical thermal Gaussian bosonic matter

This release accompanies the study Quantum energy teleportation in near-critical thermal Gaussian bosonic matter and contains the code required to reproduce the main numerical results. It implements the Gaussian bosonic framework, the quantum energy teleportation protocol in the near-critical thermal regime, and the scripts used to generate the figures and data reported in the manuscript.
