Abstract
The experimental realization of entanglement concentration without local filtering and demonstration of a universal Bell-state synthesizer are discussed. Although typical type-II SPDC is used as a source, the Bell-state synthesizer is not affected by the pump source, the crystal properties, and the use of spectral filters. In addition, a more general state, partially mixed-partially entangled state can be readily generated. This new Bell-state synthesizer will be useful in experimental studies of quantum information science and as a building block of multiparticle entanglement.
