abstract: In this work, we investigate quantum walks in different networks interacting with a pure dephasing environment. We model the quantum transport by a tight-binding hamiltonian with site-energies disorder, and introduce losses and a trapping site. With numerical methods, we investigate how the transport efficiency to this site depends on disorder and dephasing rates.
