    "abstract": "We report a novel Bell-state synthesizer in which an interferometric\nentanglement concentration scheme is used. An initially mixed polarization\nstate from type-II spontaneous parametric down-conversion becomes entangled\nafter the interferometric entanglement concentrator. This Bell-state\nsynthesizer is universal in the sense that the output polarization state is not\naffected by spectral filtering, crystal thickness, and, most importantly, the\nchoice of pump source. It is also robust against environmental disturbance and\na more general state, partially mixed$-$partially entangled state, can be\nreadily generated as well.",
