We propose an improved coding method of quantum key distribution protocols based on a recently proposed (QKD) protocol using Fibonacci-valued OAM entangled states. To be exact, we define a new class of Fibonacci-matrix coding and Fibonacci-matrix representation and show how they can be used to extend and improve the original protocols. Compared with the original protocols, our protocol not only greatly improves the encoding efficiency but also has verifiability.
