Cluster states are a class of entangled states that are maximally connected and highly resilient against noise. They can be a useful resource for measurement-based quantum computing. In this work, we present a unique approach for generating dual-rail continuous-variable cluster states in a hybrid optomechanical system that is composed of cavity modes, mechanical modes, and qubits. The scheme only relies on local interaction between neighboring modes and can be scalable to a large number of cavity and mechanical modes. We characterize the multipartite entanglement in the generated states and show that the states are robust against cavity and mechanical losses. As a direct application, we demonstrate that the entanglement in the cluster states can be transferred to two distant qubits by manipulating the cluster state via measurement.
