Single-photon-level non-Gaussian operations—photon addition, photon subtraction, and their coherent superposition—are powerful tools withwhich to increase entanglement in continuous-variable optical states. Although such operations are typically not deterministic, theremay be other advantages such as noiselessmanipulation. Therefore, to fully account for the efficacy of a particular nonGaussian operation in a practical scenario, we develop figures ofmerit which trade off the advantages of such… CONTINUE READING
