Abstract :
A Bell measurement setup that can distinguish between all Bell states on a Psi-otimesPsi- product state is described. A spontaneous parametric down conversion (SDPC) in a 2 mm type-II beta-barium borate (BBO) crystal is used. The Bell measurement is based on a linear optical control sign shift gate and single qubit rotations. The entanglement properties where studied by Bell inequalities, entanglement wetness and positive partial transpose criteria.
