A simple scheme to realize quantum teleportation with pi /2 unitarily rotated transformation for continuous variable is proposed, in which the bright entangled EPR beam is produced by phase sensitive nondegenerate optical parametric amplifier with a fixed relative phase of pi /4 between the subharmonic signal and the harmonic pump field. The measurement of "Bell state" is accomplished by means of direct detection of photocurrents. (C) 2001 Elsevier Science B.V. All rights reserved. [References: 8]
