  Quantum walks are a well-established model for the study of coherent
transport phenomena and provide a universal platform in quantum information
theory. Dynamically influencing the walker's evolution gives a high degree of
flexibility for studying various applications. Here, we present
time-multiplexed finite quantum walks of variable size, the preparation of
non-localized input states and their dynamical evolution. As a further
application, we implement a state transfer scheme for an arbitrary input state
to two different output modes. The presented experiments rely on the full
dynamical control of a time-multiplexed quantum walk, which includes adjustable
coin operation as well as the possibility to flexibly configure the underlying
graph structures.
