Abstract
As demonstrated by E. Knill et al. [Nature 409, 46 (2001)]
quantum teleportation and quantum logic gates with success probability close
to one can be implemented using only linear optical elements, additional
photons and post-selection. To do it, special quantum channels are requested
to have in sight before quantum teleportation performance. Here, we propose
experimental arrangement to generate two-photon KLM state different from
well- known Bell states. This two-photon KLM state can be used to enhance
success probability of the quantum teleportation of one-mode quantum qubit
from 0.5 up to 2/3.
