Optimal sensing of photon addition and subtraction on nonclassical light
Optical tomograms are shown to directly discriminate between a wide range of nonclassical states of light, as they are sensitive to variations in photon number, which can be quantified through the Wasserstein distance calculated from tomograms. This approach circumvents the state reconstruction procedure, and can find use in precision sensing and quantum error correction with continuous variables.
