<title>Quantum teleportation</title>

Abstract

In 1993, C.H. Bennet et. al. had proposed the protocol for quantum teleportation of unknown quantum state. Now, this phenomenon was observed experimentally and numerous applications in quantum telecommunications and informatics are proposed. This method of communication is not direct because it uses classical besides quantum channel. We propose here another scheme where protocol can be established before information transmission and then information is transmitted through quantum electro-dynamic channel of interaction between particles with entangled states. With that, parametric interaction between photons is implemented for coupling of information to this interaction channel and subsequent read out of information. In this scheme, the pair of photons with entangled polarization states is used and parametric interaction trough the field of virtual photons serves as interaction channel.
