Complete quantum teleportation with a Kerr nonlinearity [PDF]

Physical Review Letters, 2000
We present a scheme for the quantum teleportation of the polarization state of a photon employing a cross-Kerr medium. The experimental feasibility of the scheme is discussed and we show that, using the recently demonstrated ultraslow light propagation ...
