摘要：

By constructing sets of ingenious measurement bases at the sender's and the controller's locations, we devise two schemes to realize the controlled remote preparation of an arbitrary four-qubit chi-state via partially entangled quantum resource. The success probabilities of the proposed schemes are 50 % and 100 %, respectively. It means that the success probabilities are independent of the coefficients of the entangled channel.
