  We propose and develop theory of quantum teleportation of unknown qubit based
on interaction mechanism between discrete-variable (DV) and continuous-variable
(CV) states on highly transmissive beam splitter (HTBS). This DV-CV interaction
mechanism is based on simultaneous displacement of the discrete-variable state
on equal in absolute value but opposite in sign displacement amplitudes by
coherent components of the hybrid, in such a way that all the information about
the displacement amplitudes is lost with subsequent registration of photons in
the auxiliary modes
