Experimental Demonstration of Unconditional Entanglement Swapping for Continuous Variables
PHYSICAL REVIEW LETTERS PRL 93, 250503 (2004),-0001,():
The unconditional entanglement swapping for continuous variables is experimentally demonstrated. Two initial entangled states are produced from two nondegenerate optical parametric amplifiers operating at de-amplification. Through implementing the direct measurement of the Bell-state between two optical beams from each amplifier the remaining two optical beams, which have never directly interacted with each other, are entangled. The quantum correlation degrees of 1.23 and 1.12dB below the shot noise limit for the amplitude and phase quadratures resulting from the entanglement swapping are measured straightly.
