GuoXueyi/MERviaQT: First release: Numerical simulation code for "Energy Relaxation via Quantum Thermalization: A Superconducting Qubit Coupled to a Many-Body TLS System"

This release contains the numerical simulation code accompanying the manuscript "Energy Relaxation via Quantum Thermalization: A Superconducting Qubit Coupled to a Many-Body TLS System". Contents: Numerical simulation scripts for qubit-TLS chain dynamics Implementation of the full forward-time information erasure (FFTIE) sequence Code for extracting T1 and T2 relaxation times Data processing and analysis routines Requirements: Python 3.x QuSpin package (Weinberg & Bukov, SciPost Phys. 2, 003 (2017); 7, 020 (2019)) Additional dependencies: NumPy, SciPy, Matplotlib (see requirements.txt) The code reproduces the main results presented in the manuscript, including: Coherent qubit-TLS energy exchange (Figure 2) Exponential energy relaxation under thermalization (Figure 3) Parameter dependence of T1 and T2 (Figure 4) For questions or requests, please contact the corresponding author.
