Phys. Rev. A 71, 062341 (2005) [5 pages]Conditional transfer of quantum correlation in the intensity of twin beamsReceived 22 October 2004; published 30 June 2005 A conditional protocol of transferring quantum correlations in a continuous variable regime was experimentally demonstrated. The quantum correlation in two pairs of twin beams, each characterized by intensity-difference squeezing of 7.0±0.3 dB, was transferred to two initially independent idler beams. The quantum-correlation transfer resulted in intensity-difference squeezing of 4.0±0.2 dB between two idler beams. The dependence of the preparation probability and transfer fidelity on the selection bandwidth was also studied. © 2005 The American Physical Society URL:
