Abstract
An experimental system for entanglement swapping of continuous variables was designed. Two nondegenerate optical parametric amplifiers operating at deamplification were used for two independent EPR sources. Through a jointly direct measurement of Bell-state the entanglement swapping can be implemented. The level of entanglement produced from entanglement swapping depends not only on the squeezing parameter of light field but also on the large excess noise in the unsqueezed quadrature component
