Unbiased estimation of an optical loss at the ultimate quantum limit with twin-beams

Abstract Loss measurements are at the base of spectroscopy and imaging, thus permeating all the branches of science, from chemistry and biology to physics and material science. However, quantum mechanics laws set the ultimate limit to the sensitivity, constrained by the probe mean energy. This can b...
