• Abstract: We present a scheme for bidirectional remote state preparation (BRSP) using quantum walks on two independent one-dimensional lattices and two independent cycles with two and four vertices, employing nearest-neighbor jumps with coin outcomes. The protocol is implemented in two distinct ways: one without the involvement of a controller and the other assisted by a controller . In this approach, the quantum walk dynamics generate entanglement during the remote state preparation process, thereby eliminating the need for any pre-shared initial entanglement between the communicating parties. Finally, we show that the bidirectional remote state preparation schemes based on quantum walks on a two-vertex and four-vertex system exhibit consistent behavior under the respective uncontrolled and controlled configurations.
