Generation of two-photon KLM quantum channel
PACS: 03.67.Lx
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.
