Abstract
We propose a new linear optical protocol for remote state
preparation (RSP) between two parties under control of a number of
controllers in terms of optical elements. The proposed setup
involves simple linear optical elements, a N-photon polarization
entangled state, and photon detectors, witch have been widely used
in experiment. The realization of this protocol is appealing due to
the fact that quantum state of light is robust against the
decoherence and photons are ideal carriers for transmitting quantum
information over long distances.
