Teleportation and controlled teleportation with maximally four-qubit entanglement quantum states

摘要

Recently Paolo Facchi et al.~(15) presented a maximally multipartite entangled state (MMES). It is shown that some of these states can be utilized for perfect teleportation of arbitrary two-qubit systems and controlled teleportation of an arbitrary one-qubit state. Furthermore, the optimal match measuring basis are given by transformation operator for controlled teleportation.
