  We identify a mapping between two-dimensional (2D) electron transport in a
minimally twisted graphene bilayer and a 1D quantum walk, where one spatial
dimension plays the role of time. In this mapping a magnetic field B
perpendicular to the bilayer maps onto an electric field. Bloch oscillations
due to the periodic motion in a 1D Bloch band can then be observed in purely DC
transport as magnetoconductance oscillations with periodicity set by the Bloch
frequency.
