With the development of quantum computing, kinds of models of quantum computing have been proposed. Recently, more and more attentions have been paid on the quantum computing based on molecular to-vibrational states. Using this quantum computing model, the multi-qubit quantum computing and a long decoherence time can be achieved conveniently. The numerical simulations have shown that quite high fidelity quantum computing gates can be realized. Ro-vibrational entanglement is a key resource for the ro-vibrational quantum computing. Many researchers have focused on the studies of the dynamics of ro-vibrational entanglements, and such studies could provide suggestions for further researches and applications of the to-vibrational quantum computing. In this paper, the development of molecular quantum computing and ro-vibrational are briefly reviewed.
