As the quantum mechanical analog of a classical random walk, quantum walks offer a powerful framework for advancing various modern quantum technologies. Beyond their foundational significance, quantum walks can also serve as a model for universal quantum computation. However, scaling such models requires the interaction of multiple quantum walkers, a task that poses significant experimental challenges. In our research, we explore the feasibility of quantum walk computation using photonic waveguide arrays, a platform that offers inherent stability, compactness, and versatility.
