Implementation of ground resp. thermal state preparation algorithm following the quantum-channel approach presented in arXiv:2508.05703 from Ding et.al. Project for QIST master program at TU Wien, supervised by S. Andergassen and T. Ayral.
1.) Implementation of cooling algorithm for transverse Ising model as toy example
2.) Implementation of cooling algorithm for 1+2 (impurity/bath) site DMFT model.
- How does cooling work if run on a NISQ QC or with noise simulation?
- Can we assign the noise an effective temperature and what T is necessary to be able to detect a particular phase-transition (e.g. superconducting phase)?
- What computational budget is necessary to do so?
- Ressource estimation for impurity model
- Can a hybrid algorithm (first cooling, then filtering) compute a Green's function for the impurity model effectively?
- What is the optimal ressource allocation between cooling and filtering-algorithm?
