摘要：
Recently, Binayak S. Choudhury (Quantum Inf. Process 13, 239 2014), proposed a protocol of joint remote state preparation of an equatorial two-qubit pure quantum state using GHZ states. According to their scheme the probability of success is 0.25. In this letter, an improved scheme is proposed, which can enhance the probability of success to 100 %. Moreover, we propose a scheme to prepare the two-qubit pure quantum state whose coefficient is more general.
