Abstract
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 , was transferred to two initially independent idler beams. The quantum-correlation transfer resulted in intensity-difference squeezing of between two idler beams. The dependence of the preparation probability and transfer fidelity on the selection bandwidth was also studied.
