  We report on the experimental realization of electric quantum walks, which
mimic the effect of an electric field on a charged particle in a lattice.
Starting from a textbook implementation of discrete-time quantum walks, we
introduce an extra operation in each step to implement the effect of the field.
The recorded dynamics of such a quantum particle exhibits features closely
related to Bloch oscillations and interband tunneling. In particular, we
explore the regime of strong fields, demonstrating contrasting quantum
behaviors: quantum resonances vs. dynamical localization depending on whether
the accumulated Bloch phase is a rational or irrational fraction of 2\pi.
