WebJul 25, 2024 · Quantum enhanced optical measurement protocols aim at reducing the uncertainty in the estimation of some physical quantities of a system below the shot-noise limit, classically unavoidable. In particular when small number of photons is used the shot noise can be the main source of uncertainty, in these cases the use of quantum light is of … WebJan 9, 2024 · Ghosting is a light or dark area that appears in the field of vision. While it does not necessarily indicate a serious situation, it can be unpleasant if left untreated. Dry eyes or other corneal irregularities can cause ghosting.
