Under the preconditions that a (n:n)-qutrit pure state is taken as the quantum channel to teleport an arbitrary n-qutrit state and the sender is able to perform generalized-Bell-state measurements and publish the results, the necessary transformation operation in the receiver's site is worked out in terms of the technique of swapping states. A criterion on whether such quantum channel can be utilized for perfect teleportation is derived by virtue of the unitarity of the resultant transformation operator. Moreover, the flexibility between the measurement difficulty and the reconstruction difficulty is shown and discussed.
采用文献[Luo S L.Using measurement-induced disturbance to characterize correlations as classical or quantum[J].Phys Rev A,2008,77:022301]中提出的测量诱导扰动方法计算了一类2体可分量子比特-垂特关联态中的非经典关联.具体来说,就是利用谱分解技巧来获得每个态中的经典关联,继而得出其中包含的量子关联.经过对这些态中的量子关联的详尽分析,一些独特的性质被展示出来.
