摘要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.
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.
