摘要： 通过置换群和巧妙构造测量基，给出了以GHZ型态为信道三方确定性地联合地制备四粒子[χ]态和五粒子Brown态的两个协议，并将两个发送者的情况推广到多个发送者的情形，提高了已有方案的概率而不需添加额外局域操作。

Abstract: By the permutation group and constructing delicately some useful measurement bases, two deterministic protocols of three-party joint remote state preparation of arbitrary four-qubit [χ]-state and five Brown-state via GHZ-type states as quantum channel are presented, and they are generalized from the case of two senders to that of multi senders. The probability of the existing schemes is improved without extra local operations in this paper.
