Abstract
The problem of open quantum systems coupled to fermionic environments arises in a variety of fields, ranging from quantum dots to quantum transport at zero and finite temperature. This work presents and analyzes a tensor network based time integration scheme for this problem, which enables simulations of such systems with controllable and certified error. Furthermore, it is shown that performing simulations in the Heisenberg picture can lead to significant efficiency gains.
