- Abstract summary: We use discrete-event simulation on a digital computer to study two different models of experimentally realizable quantum walks.
The simulation models comply with Einstein locality, are as "realistic" as the one of the simple random walk in that the particles follow well-defined trajectories, are void of concepts such as particle-wave duality and wave-function collapse.

- Abstract: We use discrete-event simulation on a digital computer to study two different
models of experimentally realizable quantum walks. The simulation models comply
with Einstein locality, are as "realistic" as the one of the simple random walk
in that the particles follow well-defined trajectories, are void of concepts
such as particle-wave duality and wave-function collapse, and reproduce the
quantum-theoretical results by means of a cause-and-effect, event-by-event
process. Our simulation model for the quantum walk experiment presented in [C.
Robens et al., Phys. Rev. X 5, 011003 (2015)] reproduces the result of that
experiment. Therefore, the claim that the result of the experiment "rigorously
excludes (i.e., falsifies) any explanation of quantum transport based on
classical, well-defined trajectories" needs to be revised.
