Improving the precision of optical metrology by detecting fewer photons with biased weak measurement
Abstract In optical metrological protocols to measure physical quantities, it is, in principle, always beneficial to increase photon number n to improve measurement precision. However, practical constraints prevent the arbitrary increase of n due to the imperfections of a practical detector, especia...
