Abstract :
We present an entanglement swapping experiment realized for the first time with independent photon pairs created in continuous wave (CW) mode. Pairs of entangled photons are created by the process of spontaneous parametric down conversion in nonlinear periodically poled lithium niobate (PPLN) waveguide crystals. Two photons, one from each pair are combined on a beamsplitter (BS) and projected via a joint measurement onto one of the four Bell states.
