    "abstract": "We investigate the possibility of implementing a given projection measurement\nusing linear optics and arbitrarily fast feedforward based on the continuous\ndetection of photons. In particular, we systematically derive the so-called\nDolinar scheme that achieves the minimum error discrimination of binary\ncoherent states. Moreover, we show that the Dolinar-type approach can also be\napplied to projection measurements in the regime of photonic-qubit signals. Our\nresults demonstrate that for implementing a projection measurement with linear\noptics, in principle, unit success probability may be approached even without\nthe use of expensive entangled auxiliary states, as they are needed in all\nknown (near-)deterministic linear-optics proposals.",
