Abstract
We present a model to realise a probabilistic quantum
teleportation of two-particle mode entangled state through the four-photon
quantum channel. Four modes of the two-photon mode entangled state are
directly transferred to other spatial four modes of the quantum channel with
success probability of 50%.
The quantum protocol operates in space of photon
number states. A Bell state measurement with four beam splitters and four
pairs of detectors in the teleportation protocol is accomplished in the
fourfold coincidence basis.
