Abstract
A simple scheme to realize quantum teleportation with pi /2 unitarily rotat ed transformation for continuous variable is proposed, in which the bright entangled EPR beam is produced by phase sensitive nondegenerate optical par ametric amplifier with a fixed relative phase of pi /4 between the subharmo nic signal and the harmonic pump field. The measurement of "Bell state" is accomplished by means of direct detection of photocurrents. (C) 2001 Elsevi er Science B.V. All rights reserved.
