OpenTN [WIP]

Employing Locally Purified Density Operator (LPDO) tensor networks to study open quantum systems under non-local CPTP maps.

Decreasing approximation errors from the trotterization of CPTP maps on the kraus dimensions. Using Riemannian optimization on Sitefel Manifold.

Methods: Tensor Networks, Automatic Differentiation, Convex Optimization, Riemannian Optimization, Open Quantum Systems.
