  In recent times, hybrid entanglement (HE) between a qubit and a coherent
state has demonstrated superior performance in various quantum information
processing tasks, particularly in quantum key distribution. Despite its
theoretical advantages, efficient generation of such states in the laboratory
has been a challenge. Here, we introduce a deterministic and efficient approach
for generating HE states using quantum walks. Our method achieves a remarkable
fidelity of $99.9\%$ with just $20$ time steps in a one-dimensional split-step
quantum walk. This represents a significant improvement over prior approaches
for probabilistic generation of HE states with fidelity as low as $80\%$. Our
scheme not only provides a robust solution to the generation of HE states but
also highlights a unique advantage of quantum walks, thereby contributing to
the advancement of this burgeoning field. Moreover, our scheme is
experimentally feasible with the current technology.
