【摘要】We present a scheme for quantum state sharing of an arbitrary qudit state by using nonmaximally entangled generalized Greenberger-Horne-Zeilinger (GHZ) states as the quantum channel and generalized Bell-basis states as the joint measurement basis.We show that the probability of successful sharing an unknown qudit state depends on the joint measurements chosen by Alice.We also give an expression for the maximally probability of this scheme. 【总页数】4页(624-627)
