  The evolution of a many-particle system on a one-dimensional lattice,
subjected to a quantum walk can cause spatial entanglement in the lattice
position, which can be exploited for quantum information/communication
purposes. We demonstrate the evolution of spatial entanglement and its
dependence on the quantum coin operation parameters, the number of particles
present in the lattice and the number of steps of quantum walk on the system.
Thus, spatial entanglement can be controlled and optimized using a
many-particle discrete-time quantum walk.
