On Teleportation Witness Operators [PDF]
Satyabrata Adhikari, Pankaj AgrawalWe study extensively the properties of teleportation witness operators. We have also constructed a hermitian operator which can act as a teleportation witness operator. Moreover, we investigate the Schmidt number of an arbitrary mixed state useful for teleportation by constructing a Schmidt number teleportation witness that detects it. We also present a form of such witness operators.View original: http://arxiv.org/abs/1204.0983
