  Entanglement generation in discrete time quantum walks is deemed to be
another key property beyond the transport behaviors. The latter has been widely
used in investigating the localization or topology in quantum walks. However,
there are few experiments involving the former for the challenges in full
reconstruction of the final wave function. Here, we report an experiment
demonstrating the enhancement of the entanglement in quantum walks using
dynamic disorder. Through reconstructing the local spinor state for each site,
von Neumann entropy can be obtained and used to quantify the coin-position
entanglement. We find that the enhanced entanglement in the dynamically
disordered quantum walks is independent of the initial state, which is
different from the entanglement generation in the Hadamard quantum walks. Our
results are inspirational for achieving quantum computing based on quantum
walks.
