Abstract

Using the method presented recently [Phys. Rev. A 77 (2008) 014306; Phys. Lett. A 369 (2007) 377], the transformation operator (TO) is explicitly given for teleporting an arbitrary three-qubit state with a six-qubit channel and Bell-state measurements. A criterion on whether such quantum teleportation can be perfectly realized is educed in terms of TO. Moreover, six instantiations on TO and criterion are concisely shown.
