    "abstract": "Positive Operator Value Measures (POVMs) are the most general class of\nquantum measurements. We propose a setup in which all possible POVMs of a\nsingle photon polarization state (corresponding to all possible sets of\ntwo-dimensional Kraus operators) can be implemented easily using linear optics\nelements. This method makes it possible to experimentally realize any\nprojective orthogonal, projective non-orthogonal or non-projective sets of any\nnumber of POVM operators. Furthermore our implementation only requires vacuum\nancillas, and is deterministic rather than probabilistic. Thus it realizes\nevery POVM with the correct set of output states. We give the settings required\nto implement two different well-known non-orthogonal projective POVMs.",
