This study examines a quantum version of the Sinai-Derrida model for “random walk in random environment,” revealing a delocalization-transition and enhanced disorder due to coherent hopping when bias is increased beyond a critical value, and highlighting the nonmonotonic dependence of the Lindbladian spectrum on the rate of coherent transitions.
