摘要：
A proposal is presented for teleporting a single qubit that is encoded in the space spanned by two equal-amplitude and opposite-phase squeezed vacuum states (SVSs) of a harmonic oscillator. In this proposal, the quantum channel is a maximally entangled SVS. The process of the teleportation is achieved by using a 50/50 symmetric beam splitter and photodetectors, and with the successful probability of 1/4. (C) 2002 Elsevier Science B.V.
