- The Gottesman-Kitaev-Preskill (GKP) coding is proven to be a good candidate for encoding a qubit on continuous variables (CV) since it is robust under random-shift disturbance. Its preparation in optical systems, however, is challenging to realize in nowadays state-of-the-art experiments. In this article, we propose a simple optical setup for preparing the approximate GKP states by employing a random walk mechanism. We demonstrate this idea by considering the encoding on the transverse position of a single-mode pulse laser. We also discuss generalization and translation to other types of physical CV systems.
